VMC 440 Instruction Manual 4-VMC440-01© 2015 Alarmtech Rev. VMC440 1511en Page 1 of 2Magnetic ContactDESCRIPTIONMC 440 is a magnetic contact with opening contact for surface mount. It can be used in security system and industrial control systems for protection of doors and windows against unauthorized opening. It is easy to mount and has screw terminals with wire guards. It is available with build in resistors of any value and configuration on customer request. With enclosed plastic distances and separate accessories like Z-bracket and L-bracket it is possible to mount the contact on steel.CIRCUIT DIAGRAM (SHOWN WITHOUT MAGNET FIELD)Fig 1.MC 440 with configuration for separate sabotage loop:Fig.2. MC 440 with one resistor Rp parallel over reed mounted in the terminals with many contacts in a loop:Fig 3. MC 440 with two resistor mounted in the terminals for a end of line contact when only one contact used in the loop:Fig. 4. MC 440-PRpSRs with build in resistors:A = End Of Line using 2 resistors.B = using only the Rp resistor to mount more contacts on one loop.TECHNICAL DATASwitching voltage max. 48 V DC/ACSwitching current max. 400 mA DC/peak AC Contact rating max.10 WVMC 440 Instruction Manual4-VMC440-01© 2015 AlarmtechRev. VMC440 1511enPage 2 of 2OPERATING PRINCIPLEMC 440 magnetic contact has two parts: the contact part with a reed switch and the magnet part. In its neutral position the reed switch remains closed under the force of the magnetic field. Opening the monitored object increases the distance between the reed switch and the magnet. This reduces the influence of the magnetic field on the reed switch until it opens and activates an alarm.Magnetic contacts should not be installed in the vicinity of strong magnetic fields.INSTALLATIONContact and magnet should be installed in parallel, above or besides each other corresponding to each other. Offset will reduce the working distances. The contact should be mounted on the stationary part of the monitored object (ex. door frame) and the magnet on the movable part (ex. door leaf).For sites where it is impossible to mount the contact directly, spacers and aluminium brackets are available. Spacers enable installation of the contact on ferromagnetic surfaces. Brackets can be used to mount the contact parts away from a ferromagnetic surface or to solve problems with aligning the contact with the magnet. Contact and/or magnet should be screwed to the oval slots in the brackets and adjusted to a suitable position.Only non-ferromagnetic screws may be used for mounting the contact.After the installation, use an ohmmeter to check the electrical connections and test the operation of the magnetic contact.Warning: applying excessive force to the housing of the contact may damage the glass body of the reed switches inside.Warning: appropriate accessories must be used for installation in ferromagnetic environment.ORDER INFORMATIONMC 440 is standard available with build in resistors 1% tolerance of any chosen value.For model MC 400 the resistors can be self-mounted to the terminals of the product of any chosen value by installer. MC 440 is universal and can be used with one resistor parallel to the alarm switch mounted on terminal 1 and 2 and with two resistors one in parallel mounted on terminal 1 and 2 and one in series to the reed mounted on terminal 3 and 4.MC 400-PRpSRs is the universal contact with build in resistor. It is universal for one and two resistor by connecting the the loop either A to terminal 1and 2 for a parallell resistor to reed or B connected to terminal 1 and 3 for two resistors Rp and Rs. We keep stock of some units with build in standard resistor values. If in this case the two resistors have different value use S in front of the value in series and P for parallel to the reed contact when ordering. Any resistance values with tolerance 1% can be ordered with min. quantity of 100pcs.For special orders of build in resistors use the following ordering information MC 440-PRpSRs∙ Parallel to reed use prefix P and resistor value ∙ In series to reed use prefix S and resistor value ∙With the same value of Rp and Rs use MC 440-2xRORDER INFORMATIONUniversal contact with 2 resistors build in as we keep in stock. The design allows installer to use one or both.AccessoriesWe reserve the right to changes without notice.。
PCIE扩展ROM控制芯片CH366硬盘和网络安全隔离卡方案
PCIE扩展ROM控制芯片CH366硬盘和网络安全隔离卡方案版本： 11、概述安全隔离卡用于将普通计算机分为安全环境（内网）和开放环境（外网），内网和外网使用不同的硬盘并且连接到不同的网络，从而能够避免硬盘中的重要数据通过网络等方式泄露。
一般的双网卡方案、多重引导卡或者多用户管理卡只是在逻辑层提供硬盘数据隔离，而硬盘和网络安全隔离卡的特点主要是在物理层提供硬盘数据隔离，确保更高的数据安全性。
现有的技术方案主要是单网卡、双硬盘物理切换隔离，通常都需要在启动时选择内网或者外网，这些选择界面和切换操作通常由扩展ROM中的启动程序完成。
2、用户的功能需求分析①用户需要在开机后选择将使用内网的安全环境，还是外网的开放环境，所以安全隔离卡应该能够在开机时向用户提供选择界面，而且应该是在DOS或者Windows等操作系统引导之前。
②当用户选择完后，安全隔离卡需要执行内外网的环境切换，也就是说，需要在选择界面（软件）与隔离卡切换电路（硬件）之间建立通讯。
③当启动时切换选择后，必须确保不能在Windows等系统的运行过程中被黑客无意或者恶意的切换，否则将导致硬盘数据不完整以及数据通过外网泄露，所以安全隔离卡需要一个切换锁定装置。
当隔离卡在启动时切换完成后，必须锁定防止再被切换，直到关机或者重启才能解除。
④美观需求。
早期产品是从计算机后壳引出电线接一个电器开关到桌面，由用户随时拨动开关，所以就很难做到美观，也不完全，容易无意中碰到，完全不象一个高科技的IT产品。
⑤方便性和智能化，体现在软件功能上。
新式的隔离卡通常采用扩展ROM程序，根据用户的使用习惯提供仿Windows中文界面和智能提示，以及个性化的启动图片。
⑥方案的统一性和可升级性。
同一方案既能支持PATA并口硬盘，也能支持SATA串口硬盘，便于批量采购和备货，便于简化售后服务。
⑦软硬件的兼容性，由所采用的技术方案而定。
例如，IDE接口只用于硬盘和光驱产品，当前的UDMA133硬盘工作在133MHz高频上，如果通过拦截硬盘IDE接口获取扩展ROM发出的切换指令，那么就会增加IDE接口的负载，对于更高速度的SATA接口则问题更严重，很容易产生主板兼容性问题，或者影响硬盘数据的传输速度，好的技术方案应该尽量采用成熟的标准化技术，例如通过PCI-Express总线的I/O端口获取扩展ROM发出的切换指令。

基于PROTEUS的输、受血一体的血型匹配指示电路设计作者：周灵彬来源：《数字技术与应用》2017年第11期摘要：现有的血型匹配电路或功能单一，只具有输血匹配或受血匹配指示功能；或关注器件应用的技术性而忽略了实用性。
故设计一种直观、方便操作的输、受血匹配指示电路。
主要由数字门电路、模拟开关组成，并通过一按键来切换输、受血状态。
本电路在PROTEUS仿真软件中测试成功。
关键词：血型匹配；门电路；模拟开关；仿真中图分类号：TN79 文献标识码：A 文章编号：1007-9416（2017）11-0181-03人类基本血型有四种：A、B、AB和O型。
输血时输血者的血型与受血者的血型不是简单的可逆关系，而必须符合一定的授受关系，如图1所示。
即：（1）O型血可输给任意血型的人，但O型血的人只能接受O型血；（2）AB型血只能输给AB型的人，但AB血型的人能接受所有血型；（3）A型可输给A型与AB血型的人，但只接受A型血与O型血；（4）B 型血可输给B型与AB血型的人，但只接受B型血与O型血。
1 由数据选择器等搭建的血型匹配电路[1-2]现有的血型匹配电路或只实现了单一的输血或是受血指示功能；或是注重元件应用而实现的匹配电路，常见的设计思路如下：4种血型可以用两个逻辑变量组合表示，假设00代表A 型、01代表B型、10代表AB型、11代表O型。
那么输血与受血就需要两组两位逻辑变量，是否匹配成功可用一位逻辑变量表示。
如此得到如表1的真值表。
在要求用八选一数据选择器（74151）等来实现时，由真值表得到表2所示的卡诺图，因此逻辑式可以表示为：Y=m0D'+m1D'+ m2D+m3D'+m5D’十m6+m7故：D0=D1=D3=D5=D'，D2=D，D4=0，D6=D7=1。
根据74151的功能表，如图2所示，结合上式，可设计出如图3所示的血型匹配指示电路。
要判断血型是否匹配，必须要将表1和图3结合起来看。

二、常用的CMOS模拟开关集成电路
在模拟开关的集成过程中，晶体三极管和场效应 晶体管均可用来做模拟开关的有源器件，实际上，由 于场效应晶体管特性的对称性不存在残余电压等优点， 所以在模拟开关中用的最多的还是场效应晶体管。
• 开关在电路中起接通信号或断开信号的作用。最常见的 可控开关是继电器，当给驱动继电器的驱动电路加高电 平或低电平时，继电器就吸合或释放，其触点接通或断 开电路。
注意：
AD7501，AD7502，AD7503 芯片都是单向多 到一的多路开关，即信号只允许从多个 (8个) 输入端 向一个输出端传送。
单八路模拟开关CD4051
• CD4051相当于一个单刀八掷开关，开关接通哪一通 道，由输入的3位地址码ABC来决定。
• “INH”是禁止端，当“INH”=1时，各通道均不接通。 • CD4051还设有另外一个电源端VEE，以作为电平位移
