The bolt pads are to have equal gaps on each side of the coupling.Notice: Visually inspect both sides of the coupling to ensure gaps between bolt pads are evenly spaced and are parallel. Anydeviations must be corrected before placing coupling into service.Notice: Sizes 16" and larger are cast inmultiple segments. To install the larger sizes align the tongue and pocket of the couplings appropriately and tighten the nuts alternately to the specified bolt torque. When properly assembled there will be a small equal gap between the adjacent bolt pads.ANSI Specified Bolt TorqueBolt SizeWrench SizeSpecified Bolt Torque*In.In.Ft.-Lbs3/811/1630-451/27/880-1005/811/16100-1303/411/4130-180115/8200-250* Non-lubricated bolt torques.1 Check & Lubricate GasketCheck gasket to be sure it is compatible for the intended service. Apply a thin coating of Gruvlok lubricant to the exterior surface and sealing lips of the gasket. Someapplications require lubrication of the entire gasket surface. Be careful that foreign particles do not adhere to lubricated surfaces.Notice: Gruvlok Xtreme Lubricant must be applied when used in dry pipe systems or freezer applications. separation. Pipe joint separation may result in significant property damage and serious injury.2 Gasket InstallationSlip the gasket over the pipe end making sure the gasket lip does not overhang the pipe end.On couplings 10" and larger it may be easier to turn the gasket inside out then lubricate and slide the gasket over the pipe end as shown.3 AlignmentAfter aligning the two pipe ends, pull the gasket into position centering it between the grooves on each pipe. Gasket should not extend into the groove on either pipe.On couplings 10" and larger, flip or roll the gasket into centered position.4 HousingsRemove one nut and bolt and loosen the other nut. Place one housing over the gasket, making sure the housing keys fit into the pipe grooves. Swing the other housing over the gasket and into the grooves on both pipes, making sure the tongue and recess of each housing is properly mated. Reinsert the bolt and run-up both nuts finger tight.5 Tighten NutsSecurely tighten nuts alternately and equally, keeping the gaps at the bolt pads evenly spaced.Notice: Uneven tightening may cause the gasket to pinch. Gasket should not be visible between segments after bolts are tightened.Check pipe ends for proper grooved dimensions and to ensure that the pipe is free of indentations, projections, or other imperfections that would prevent proper sealing of the gasket.F ig.7401 Rigidlok ® Coupling234516。

●对设备进行过交流故障、雷电和开关暂态过程的过电压保护●为了安全，用于不同的金属间的去耦合，这些会属在某些情况下会有交流耦合。
●在阴极保护系统中，电气设备的交流接地和直流隔离。
●消减交流感应电压。
在去耦合不同的金属时，固态去耦合器可用于两个接地系统之间，或应用在其它需要交流搭接的构筑物之间，同时防止这些构筑物之间的电偶腐蚀。
性能参数隔离电压当电压低于所选定的隔离电压时，固态去耦合器阻断直流电流流通，而允许交流电流通过。
当电压高于所选定的隔离电压时，固态去耦合器成为一个双向导电装置，允许所有的电流通过，以限制构筑物上的电压。
直流泄漏电流与隔离电压的关系正常情况下，20℃时各种型号的固态去耦合器在最大隔离电压下的直流泄漏电流均小于10mA，70℃时小于100mA，正常的阴极保护电压作用在固态去耦合器上时，在两种温度条件下的漏电电流通常都小于1mA，这个数值对于阴极保护系统来说，是微不足道的。

贴片光电耦合器简介及应用
光电耦合器(以下简称光耦)是一种发光器件和光敬器件组成的光电器件。
它能实现电一光一电信号的变换，并且输入信号与输出信号是隔离的。
U前极大多数的光耦输入部分采用神化镣红外发光二极管，输出部分釆用硅光电二极管、硅光电三极管及光触发可控硅。
这是因为峰值波长900~940nm的神化稼红外发光二极簣能与硅光电器件的响应峰值波长相吻合，可获得较高的信号传输效率.光耦的结构光耦的内部结构(剖面)如图1所示。
光耦输入部分大都是红外发光二输岀部分有不同的光敬器件，如图2所示。
光敏器件管心塑料封装外喘发光簷管心透明硅胶电极引脚这里要说明的是，图2 (c)的输入部分有两个背对背的红外发光二管,它用于交流输入的场合；图2 (d)采用达林顿输出结构，它可使输出获得较大的电流；图2 (e)、2(f)的输出山光触发双向可控硅组成，它们主要用来驱动交流负载。
图2(e)与图2 (f)的差别是图2(f)有过零触发控制(图中的“ZC”即“过零”的意思)，而图2(e)没有过零触发控制电路。
基本电路光耦的基本电路如图3所示•图3 (a)的负载电阻RL接在发射极及地之间，图3 (b)的负载电阻RL接在电源Vdd与集电极之间.在图3 (R中，输入端加上Vcc电压，经限流电阻Rin后,有一定的电流IF 流经红外发光二极管，IF与Vcc、发光二极管的正向压降VF及Rin的关系为:I F二(Vcc-VF)/Rin。
式中的VF取1。
3V« IF的最大值由资料给出(一般工作时IF WlOmA)・发光二极管发光后,光电三极管导通，集电极电流Ic III Vdd经光电三极管流过RL到地，使输出电压Vout=IcXRL(或Vout二Vdd—VCE, VCE为光电三极管的管压降)。
图3(b)的工作原理与图3 (a)相同，不再重复。
图3中输入、输出也可用各自的地。
从图3 (a)可以看出；输入端不加Vcc电压，输岀端Vout=0V,输入端加了V CC 电压，负载得电，这个功能相当于“继电器”。

V I S H AY S E M I C O N D U C T O R SOptocouplers and Solid-State RelaysHow to Use Optocoupler Normalized CurvesA P P L I C A T I O N N O T By Dimitrij Martins and Lars BayerINTRODUCTIONOptocouplers are used for signal transfer between a safe and a potentially hazardous or electrically noisy environment using galvanic isolation. The isolation voltage and noise rejection characteristics of the optocoupler are basically determined by the mechanical package design and isolating materials.A phototransistor optocoupler has an infrared emitting diode, which is optically coupled to a silicon phototransistor detector. The infrared light of the LED irradiates the photosensitive base collector junction of the phototransistor which is amplified by the collector current of the transistor.HOW TO USE THE NORMALIZED CURVESThe gain of the optocoupler is expressed as a currenttransfer ratio (CTR), which is the collector current (I C ) of the output divided by the forward current (I F ) of the input andmultiplied by 100 %. (1)There are typically a number of CTR groups (binning) to choose from when selecting an optocoupler. CTR is nota static value. t is affected by the forward current (F ),the collector-emitter voltage (V CE ), and the ambient temperature (T amb ). The datasheets include curves that show how each of these values can change based on ambient temperature. To be able to compare the performance of the optocoupler over temperature we normalize the curves. Normalization is the scaling of data to a nominal condition, typically at 25 °C and the coupler-specific forward current, as the graph in Fig. 1 shows (NCTR at T amb = 25 °C and I F = 5 mA is 1.0).Fig. 1 - Normalized Current Transfer Ratio (non-saturated) vs.Ambient TemperatureTwo separate CTRs are often needed to complete the interface design. One for the non-saturated or linear operation with a collector emitter voltage (V CE ) of 5.0 V and the second one for the saturated or switching operation witha collector emitter voltage (V CE ) of 0.4 V. The Fig. 1 illustratesthe normalized CTR curves vs. forward current for different ambient temperatures for the non-saturated operation and Fig. 2 for the saturated operation.CTR = I CI F---- x 100 %0.20.4 0.6 0.8 1.0 1.2N C T R - N o r m a l i z e d C T R (n o n -s a t u r a t e d )-60-40-2020406080100120T amb - Ambient Temperature (°C)How to Use Optocoupler Normalized CurvesA P P L I C A T I O N N O T Fig. 2 - Normalized Current Transfer Ratio (saturated) vs.Ambient TemperatureThe normalized form of the CTR graph in Fig. 3 and Fig. 4 provides a reference for a quick estimation on the variation of the CTR at different forward currents and ambient temperatures ranging from -55 °C to +100 °C.Fig. 3 - Normalized Current Transfer Ratio (non-saturated) vs.Forward CurrentFig. 4 - Normalized Current Transfer Ratio (saturated) vs.Forward CurrentThe following design example illustrates how the normalized curves can be used to calculate the appropriate load resistors.Example 1Using the VOL617A-3 optocoupler with a CTR range of 100 % to 200 % at a forward current of 5 mA in thenon-saturated mode with following conditions: T amb = 0 °Cto +70 °C, I F = 5 mA, V CC = 5 V, V CE = 0.4 VSOLUTIONStep 1Determine the saturated NCTR factor for the required temperature from 0 °C to +70 °C and a forward current of 5 mA by using Fig. 5.Fig. 5 - Normalized Current Transfer Ratio (saturated) vs.Ambient Temperature0.20.4 0.6 0.8 1.0 1.2 N C T R - N o r m a l i z e d C T R (s a t )-60-40-2020406080100120T amb - Ambient Temperature (°C)00.20.40.60.81.01.21.40.1110100N C T R -N o r m a l i z e d C T R (N S )I F -Forward Current (mA)0.20.40.60.81.01.20.1110100N C T R -N o r m a l i z e d C T R (s a t )I F -Forward Current (mA)N C T R - N o r m a l i z e d C T R (s a t .)T amb - Ambient Temperature (°C)0.75How to Use Optocoupler Normalized CurvesA P P L I C A T I O N N O T With the temperature range of 0 °C to +70 °C the CTR undergoes a change between 0 % and -25 % at a forward current of 5 mA.The CTR sat range over the required temperature will be about 100 x 0.75 = 75 % to 200 % x 0.75 = 150 % for a forward current of 5 mA. Step 2Select the load resistor using the following equation: (2)Example 2:Using an VOL617A-3 optocoupler in the circuit shown in Fig. 6, determine the worst-case load resistor under the following operation conditions:T amb = 75 °C, I F = 7 mA, V CC = 5 V, V CE = 0.4 V, logic load = microcontroller I/O VOL617A-3 characteristics:CTR non-sat. = 100 % at F = 5 mA, V CE = 5.0 V, and T amb = 25 °CFig. 6 - VOL617A-3 to Microcontroller InterfaceSOLUTIONStep 1Determine the saturated NCTR factor for the ambienttemperature of 75 °C and a forward current of 7 mA, which can be found in Fig. 7.Fig. 7 - Normalized Current Transfer Ration (saturated) vs.Forward CurrentThe saturated NCTR factor is 0.71.Assuming a ten year service life period of the interface circuit, allowance needs to be made for additional CTR reduction of approximately 20 % on account of degradation.Making an additional tolerance allowance of approximately -25 % for the CTR will result in a safe minimum value of approximately 42.6 %.(4) (5)Step 2Select the minimum load resistor using the followingequation:(6)R L V CC - V CEsat.I F x CTR sat.-------------------------------- 5 V - 0.4 V 5 mA x 0.75-------------------------------- 1.22 k ≥≥≥ΩV 00.20.40.60.711.01.20.1110100N C T R -N o r m al i z e d C T R (s a t )I F -Forward Current (mA)0.8CTR sat. = CTR min. x NCTR x aging x toleranceCTR sat. = 100 % x 0.71 x 0.8 x 0.75 = 42.6 %R Lmin.V CC - V CEsat.I F x CTR sat.-------------------------------- 5 V - 0.4 V 7 mA x 0.426----------------------------------- 1.54 k ≥≥≥Ω。
