MAIN BOARD1.SUPPLY VOLTAGE The proportional amplifier requires an external DC power supply.Adiode on theinput protects the board against a power supply connected with the wrong polarity.Because the amplifier is a DC/DC converter the current consumption is less thanthe solenoid current.Several amplifiers can be connected to one power supply,which then has to meetthe following requirement:P MAX=n x P1(P1=requirement for one board,n=number of boards connected in parallel).The DC voltage must be between20and32VDC.When the amplifier is used tocontrol a valve with a24V solenoid then a voltage supply at the top end of thetolerance band(at least>26V)is recommended.This is to ensure that thesolenoid has sufficient current at higher temperatures.B/D28=+V SupplyB/D30=0V SupplyZ2,Z32=Earth(necessary for EMV)There is a current compensating coil in the supply line,with the result that the0Vline of the supply voltage is not identical with the ground potential of the amplifier.For this reason no connection may be made between the0V line of the supplyvoltage and the analogue ground of the amplifier!2.REFERENCE VOLTAGES The reference voltages±15V and±10V(stabilised)are generated by a switchedmode DC/DC converter on the board.B2=+15V unstabilised approx.50mAB4=−15V unstabilised approx.50mAD2=+10V stabilised approx.10mAD4=−10V stabilised

amplifier has a stabilised24VDC supply for transducers,positionswitches etc.D6,D32=+24V stabilised approx.80mAB6=GND5FUNCTIONAL DESCRIPTION MAIN BOARD MAND INPUTFive different current and voltage signals can be connected to the proportional amplifier.This accommodates all the industry standard input signals.The com-mand input is set up as a differential input.Adaptation for the different input voltages and compensation for the different input currents is made by setting the DIP switches and jumpers (JP4and JP5)on the main board (see page 13)accordingly.It is essential that the correct jumper and DIP switch settings are made.If the jumper and/or DIP switch settings are incorrect then the amplifier will not be able to generate the correct output current corresponding to the commandsignal.D12=positive command voltageB12=negative command voltage3.1COMMAND INPUT WITHDIFFERENTIAL INPUT FUNCTIONBecause a differential amplifier can only work correctly when,for the input and feedback resistances,particular resistance combinations are selected (SW2/1...8),this amplifier can only be used as a differential input amplifier when it is set up for a 10V input signal.The diagram to the left shows the settings for a 10V input signal with differential input function.Jumper ”JP4“and ”JP5”must be open.DIP switches SW2/2&SW2/4must be closed(ON).SW2MAND INPUT WITHOUTDIFFERENTIAL

WITHOUTDIFFERENTIAL INPUT FUNCTION(continuation)3.2.40...+10V COMMAND SIGNAL Jumper ”JP4“and Jumper ”JP5“must be open DIP switch SW2/4must be closed (ON)!An input signal voltage of 0...+10V generates an output current of 0...l MAX A .This command signal is normally used when an external command signal potentio-meter is used.See also the description below:Command from external potentiometer (see 3.2.6)or external signal source (see 3.2.7).The input impedance is 200k ¸.SW23.2.5CUSTOMISED COMMAND SIGNAL Jumper ”JP4“and Jumper ”JP5“must be open DIP switch SW2/1must be closed (ON)!If a command signal voltage is used which does not correspond to any of the above values (for example 0...+15V corresponding to 0...+100%command signal)the appropriate DIP switch has to be correspondingly set and the resistor R83(see page 13)has to be calculated according to the maximum voltage level and fitted to the board.The value of the resistance is calculated as follows:R83=V IN x 20k ¸/V Example:Command signal 0...+15V.R83=15V x 20k ¸/V =300k ¸.The existing resistor must be then replaced with a resistor having the value calcula-ted as above.The input impedance is equal the new value ofR83.SW23.2.6COMMAND VALUE FROM AN EXTERNAL POTENTIOMETER As standard a 10k ¸command potentiometer (minimum4.7k ¸)should be used.This is then connected to +10V amplifier reference voltage (pin D2)and the GND (pin B6).The wiper of the potentiometer is connected to the command signal input (pinD12).3.2.7COMMAND VALUE FROM AN EXTERNAL SIGNAL SOURCE An external signal source can also be used as a command signal (for example a PLC analogue output).In this case the ground of the signal source and the ground of the control board (pin B6)must be connected and also the signal output con-nected to the command input (pin D12).The DIP switch must be set according to the maximum input command voltage.When the command signal value is to be used as a differential input then the exter-nal signal source must be connected to D12and B12.The DIP switch settings and the level of the command voltage must be set as described under ”Command Input with Differential Input Function”(page 6).FUNCTIONAL DESCRIPTION MAIN BOARD 84.DITHERThe proportional amplifier has a square wave generator.This dither signal is super-imposed on the command for the output current.Both signals together give the valve current.The superimposed AC-content of the current reduces the hysteresis and friction of the valve.The 4pole DIP switch SW6permits 1from 3preset frequen-cies to be selected.Important!Only one (1)DIP

setting see page 15,16.4.3DITHER AMPLITUDE The dither amplitude can,if necessary,be accurately set within the range 0...300mAby adjustment of the ”dither”potentiometer RTR5(see layout diagram page 13).The factory setting is listed on page 3(REFERENCE TABLE)Adjusting the potentiometer in an anticlockwise direction increases the amplitude and viceversa.SW65.MAXIMUM CURRENT RANGEThe maximum output current at 100%command signal value can be set by adjusting the SMD multi turn potentiometer RTR3on the main board.The adjust-ment using the SMD potentiometer should not normally be made by the customer.Caution:Wrong adjustments can cause malfunctions or serious damages at the proportional amplifier and the proportional solenoid.On the main board there is a 4pole DIP switch (SW3)with which the maximum current value can be selected (see layout diagram page 13).Important!Only one switch of SW3in the closed (ON)position.SW3/1=closed (ON)400mA SW3/2=closed (ON)800mA SW3/3=closed (ON)1600mA

functions.When an external voltage supply is used for digital control then it is essential thatthe0V of the voltage source is connected with pin B20(digital GND).When voltage isolation is not essential then the24VDC supply from the amplifier(pin D6or D32)can be used for the control.In this case it is essential however,toconnect pin B20(digital GND)to one of the pins Z28,Z30or B6(analogue GND).The permitted voltage level+V digital must be in the range+4VDC to32VDC.The current consumption is approx.5mAper input at24V.6.1STOP The stop input can be used to switch the amplifier on and off.This input is anormally closed contact,in other words when there is no voltage at the input the”Fail Safe”LED is on and the amplifier is in the”Stop”state.The ramp generator isbypassed and the output stages are switched off.B16=+V digitalB20=GND digital6.2RAMP OFF With this input the ramp function can be switched on or off.This input is a normallyopen contact,in other words only when a voltage is applied to the input,the LED”Ramp OFF”is on and the output current to the solenoid corresponds to thecommand signal without delay.B18=+V digitalB20=GND digital7.SENSOR INPUTS For open loop amplifier there are no sensor inputs available.8.CONTROL OUTPUTS For open loop amplifier there are no control outputs available.9FUNCTIONAL DESCRIPTION ANALOGUE SUB BOARD10The following functions are to be found on the analogue sub board!9.JUMPER JP1-JP2The signal at the command measuring point can be selected with these jumpers.Only jumper JP1or JP2may be closed!9.1COMMAND MEASURING POINT When jumper JP1is closed the signal after the ramp generator and the l MIN and l MAXsettings can be measured at the test socket”Command”.0...100%command value=0...–x V(x≤10depending on the l MIN and l MAX settings)When the jumper JP2is closed the signal after the first amplifier stage can bemeasured at the test socket”Command”.0...100%command value=0...–10V(independent of whether the command value to the amplifier is acurrent or voltage signal)TroubleshootingIn the event of a fault jumpers JP1and JP2can be used to identify the source of theproblem.If the jumper JP2is closed and when the command value is changed acorresponding change in the range0...−10V is observed at the test socket”Command”then the main board is operating correctly.If the jumper JP1is closed and it is observed that the signal at the test socket”Command”is affected when the l MIN or l MAX potentiometers are adjusted then it canbe assumed that the sub board is operating correctly.The fault can then only be in the final stage of the current control,the dither genera-tor or the PWM generator on the main board.9.2JUMPER JP3This jumper is for special functions of other valves or valve groups.If the amplifier isused with pressure valve P2(VP01B design),4VP01,4RP01or proportionaldirectional valve4DP02E,4DP03E,4DP06E then the jumper JP3must be closed.9.3JUMPER JP4,JP5,JP6,JP7,JP8These jumpers are for special functions for different valves or valve groups.Ifthe amplifier is used with pressure valve P2(VP01B design),4VP01,4RP01orproportional directional valve4DP02E,4DP03E,4DP06E the following jumperconfiguration applies:JP4=closedJP5=not closedJP6=closedJP7=not closedJP8=closed(see also jumper and DIP switch setting pages15,16).9.4CURRENT MEASURING POINT At this measuring point there is a voltage signal proportional to the current.1V‰1A±10%.9.5FEEDBACK MEASURING POINT For open loop amplifier there is no feedback measuring point available.FUNCTIONAL DESCRIPTION ANALOGUE SUB BOARD10.TRIMMINGPOTENTIOMETERS10.1l MIN SettingThe minimum output current and so the initial valve pressure or flow can be adjusted with the l MIN potentiometer.The range of adjustment for l MIN is between 0mA and 50%of l MAX .Clockwise adjustment of the potentiometer increases the l MIN value and vice versa.10.2l MIN Step FunctionThe l MIN step function is necessary when the valve current should be 0mADC (plus effective dither value,see reference table page 3)with a command of 0V.At 0V command there is no current to the valve.When the command is only slightly above 0V (approx.1.5%of the maximum command value)then the current jumps from 0to l MIN (see 10.1).10.3l MAX SettingThe maximum output current can be limited by adjusting the l MAX potentiometer.In this way it is possible to limit the maximum pressure or flow of the valve to a lesser value than the rated flow.The value of l MAX can be set in the range l MIN to 3000mA.Clockwise adjustment of the potentiometer increases the l MAX value and vice versa.l MAXl MIN1.5%100%Command11.RAMPS The amplifier has a ramp generator.Without the ramp function the output current follows the command signal directly.With two potentiometers the acceleration and deceleration rate can be separately and independently set up in the range 1....50V/s (±20%).Clockwise adjustment of the potentiometer reduces the acceleration time (more time for the pressure increase)and vice versa.1V/s corresponds to 10s ramp time for a command jump from 0to 10V.50V/s corresponds to 200ms ramp time for a command jump from 0to 10V.VV/sV/stTEST AND SET UP

比例放大板实验调试报告VT-3013(3014)BS30型一、实验目的:1、DA模块接线。
2、比例放大板接线。
3、比例放大板输出电流检测。
(1)电流表或万用表接电阻(40W,20Ω)串接进电路直接测输出电流。
注:比例放大板是恒流源,必须串接电阻,否则会烧坏万用表。
(2)测量DA模块差动电压(16A,16C)再换算。
(3)测试孔BU2,BU3用直流电压档测,约等于电流值。
4、组态。
5、电位器及电位器型传感器调整比例阀板电流。
6、拉绳传感器及AD模块接线。
二、实验原理:1、D/A模块:模拟信号与数字信号的转换模块。
(AD模块将模拟信号转成数字信号,DA模块是将数字信号转成模拟信号)2、放大板工作原理就是几级放大,把弱的模拟信号放大几百倍后再输出,是按比例放大的,就是输入信号×放大倍数=输出信号。
3、PLC加DA转换模块,就是把PLC内的数字量转化成模拟量,变成0-10V电压,而比例阀是可以接受模拟的电压电流信号的,但是与PLC的DA模块输出的电压、电流信号可能不一致,所以需要一个中间放大环节,把PLC的D/A模块输出的信号放大成比例阀能接受的电压或电流信号。
4、实验台系统采用24v开关电源供电,根据比例阀的输出特性,选择电流表、功率表等作为测量工具。
使用PC机作为上位机,读取模拟量模块数值、编写调试程序。

(30a,+V)比例电磁铁线圈B两端分别接28A和22A;两端可以互换。
(28a,+V)(2)比例控制器需直流24V供电电源正极接32A(或32C);电源负极接26A(或26C);本控制器需单独使用电源,不能与其他用电元件共用一个电源。
(二)可编程控制器(PLC)、DA模块接线函数发生器(此处为DA模块)等给出±10V差动电压从16A,16C两端输入正电压控制电磁铁B,负电压控制电磁铁A。
LMV301 CMOS 操作放大器数据表说明书
DATA SHEET Operational Amplifier,Rail-to-Rail, Low Input BiasCurrent, 1.8 V to 5 VSingle-SupplyLMV301The LMV301 CMOS operational amplifier can operate over apower supply range from 1.8 V to 5 V and has a quiescent current ofless than 200 m A, maximum, making it ideal for portablebattery−operated applications such as notebook computers, PDA’s andmedical equipment. Low input bias current and high input impedancemake it highly tolerant of high source−impedance signal−sources suchas photodiodes and pH probes. In addition, the LMV301’s excellentrail−to−rail performance will enhance the signal−to−noiseperformance of any application together with an output stage capableof easily driving a 600 W resistive load and up to 1000 pF capacitiveload.Features•Single Supply Operation (or $V S/2)•V S from 1.8 V to 5 V•Low Quiescent Current: 185 m A, Max with V S = 1.8 V•Rail−to−Rail Output Swing•Low Bias Current: 35 pA, max•No Output Phase−Reversal when the Inputs are Overdriven•These are Pb−Free DevicesTypical Applications•Portable Battery−Powered Instruments•Notebook Computers and PDAs•Cell Phones and Mobile Communication•Digital Cameras•Photodiode Amplifiers •Transducer Amplifiers •Medical Instrumentation •Consumer ProductsORDERING INFORMATIONPIN CONNECTIONMARKING DIAGRAMSC70−5SQ SUFFIXCASE 419ASTYLES 3See detailed ordering and shipping information in the dimensions section on page 11 of this data sheet.+INV EE−INV CCOUTPUTSTYLE 3 PINOUT+−12354AAD M GGLMV301= Specific Device CodeM= Date CodeG= Pb−Free Package(Note: Microdot may be in either location)*Date Code orientation and/or position mayvary depending upon manufacturing location.MAXIMUM RATINGSSymbol Rating Value Unit V S Power Supply (Operating Voltage Range V S = 1.8 V to 5.0 V) 5.5V V IDR Input Differential Voltage±Supply Voltage V V ICR Input Common Mode Voltage Range−0.5 to (V+) + 0.5V Maximum Input Current10mA t So Output Short Circuit (Note 1)ContinuousT J Maximum Junction Temperature (Operating Range −40°C to 85°C)150°C J A Thermal Resistance (5−Pin SC70−5)280°C/W T stg Storage Temperature−65 to 150°C Mounting Temperature (Infrared or Convection (30 sec))260V ESD ESD ToleranceMachine ModelHuman Body Model 1001500VStresses exceeding those listed in the Maximum Ratings table may damage the device.

数字式比例放大器
外部设定电压不允许持续在调节范围参考值之下或之上 1V,否则就作为比例放大器的误操作。 如果在设定过程中或启动时有故障,请检查电源;如带桥式整流器,则要检查是否有电解电容(至少 1A 绕组电流 2200μF)和电源并联?放大器的电源电压是否足够高?带载时的电源电压必须比无比例放大 器是线圈热态产生的最大电流 Imax 所需的电压高 1.8VDC。 当此放大器用作一简单比例放大器控制单比例电磁铁时,请参考后面章节
无线电干扰
在一些罕见的情况,比例放大器在使用现场会遭遇电磁干扰(例如接通的是一个不抗干扰或抗干扰能力 差的电磁阀)。这种情况下,最好是对电磁阀增补抗干扰措施,或在标准放大器支架中供电线路的正导 线上,串接无线电抗干扰扼流圈(在工程机械液压技术中,例如可用带电容的抗干扰扼流圈)

电源
施加工作电压后,内部 电源 [6] 会提供比 测量零位 (M0) 高 或低 9 V 的电压。这相当于负载零位 (L0) 电压升高 +9 V。 +9 V 和 –9 V(相对于 L0 的 –9 V)电压将供给接线端口 X1,从而可以在外部(例如,供控制值电位计)使用。最大 负载是 25 mA。

注意
使用外部时间电位计时,必须将内部电位计的斜坡电位计设 置为其最大值(测量插口“t1”和“t2”处的电压约为 20 mV)。 外部电位计的电阻值(约为 500 kΩ)并联内部电位计电阻 时,最大斜坡时间会缩短。在这种情况下,无法分别调整 上,下斜坡的斜坡时间。
