采样/保持器的工作原理
当开关K闭合时，输入信号通过电阻向电容C充电，使输出 跟随输入变化此时为采样状态；要求充电时间越短越好，
以使电容电压迅速达到输入电压值。
当开关K断开时，由于电容具有一定的容量，仍能够使输 出保持不变，此时为保持状态；电容维持稳定电压的时间 越长越好，电容容量的大小将决定采样/保持器的精度。

Allow 50.8 mm (2 in.) of space on all sides for adequate ventilation, as shown.Mounting Dimensions and DIN Rail MountingDIN Rail MountingThe module can be mounted using the following DIN rails: 35 x 7.5 x 1 mm (EN 50022 - 35 x 7.5).Before mounting the module on a DIN rail, use a flat-blade screwdriver in the DIN rail latch and pry it downwards until it is in the unlatched position.1.Hook the top of the DIN rail mounting area of the controller onto the DIN rail, and then press the bottom until the controller snaps onto the DIN rail.2.Push the DIN rail latch back into the latched position.Use DIN rail end anchors (Allen-Bradley® part number 1492-EA35 or 1492-EAHJ35) for vibration or shock environments.To remove your controller from the DIN rail, pry the DIN rail latch downwards until it is in the unlatched position.For environments with greater vibration and shock concerns, use the panel mounting method, instead of DIN rail mounting.Mounting dimensions do not include mounting feet or DIN rail latches.or 2085-IOF4K2085-IF8KMicro800 4-channel and 8-channel Analog Voltage/Current Input and Output Modules Installation InstructionsPanel MountingThe preferred mounting method is to use two M4 (#8) per module. Hole spacing tolerance: ±0.4 mm (0.016 in.). For mounting dimensions, see the Micro830®, Micro850, and Micro870 Programmable Controllers User Manual, publication 2080-UM002.Follow these steps to install your module using mounting screws.1.Place the module next to the controller against the panel where you are mounting it. Make sure that thecontroller and module are spaced properly.2.Mark drilling holes through the mounting screw holes and mounting feet then remove the module.3.Drill the holes at the markings, then replace the module and mount it.Leave the protective debris strip in place until you are finished wiring the module and any other devices. System AssemblyThe Micro800 expansion I/O module is attached to the controller or another I/O module by means of interconnecting latches and hooks, as well as the bus connector. The controller and expansion I/O modules must terminate with a 2085-ECR Bus Terminator module.Be sure to lock the module interconnect latches and tighten the RTB hold down screws before applying power to the module.For installation of the 2085-ECR module, see the Micro800 Bus Terminator Module Installation Instructions, publication 2085-IN002.Field Wiring ConnectionsIn solid-state control systems, grounding and wire routing helps limit the effects of noise due to electromagnetic interference (EMI).Wire the ModuleIncluded with your 2085-IF4, 2085-OF4, or 2085-OF4K module is a single 12-pin Removable Terminal Blocks (RTB).

AD0809中文资料
ADC0809中文资料ADC0809是带有8位A/D转换器、8路多路开关以及微处理机兼容的控制逻辑的CMOS组件。
它是逐次逼近式A/D转换器，可以和单片机直接接口。
（1）ADC0809的内部逻辑结构由下图可知，ADC0809由一个8路模拟开关、一个地址锁存与译码器、一个A/D转换器和一个三态输出锁存器组成。
多路开关可选通8个模拟通道，允许8路模拟量分时输入，共用A/D转换器进行转换。
三态输出锁器用于锁存A/D转换完的数字量，当OE端为高电平时，才可以从三态输出锁存器取走转换完的数据。
（2）．ADC0809引脚结构ADC0809各脚功能如下：D7-D0：8位数字量输出引脚。
IN0-IN7：8位模拟量输入引脚。
VCC：+5V工作电压。
GND：地。
REF（+）：参考电压正端。
REF（-）：参考电压负端。
START：A/D转换启动信号输入端。
ALE：地址锁存允许信号输入端。
（以上两种信号用于启动A/D转换）.EOC：转换结束信号输出引脚，开始转换时为低电平，当转换结束时为高电平。
OE：输出允许控制端，用以打开三态数据输出锁存器。
CLK：时钟信号输入端（一般为500KHz）。
A、B、C：地址输入线。
ADC0809对输入模拟量要求：信号单极性，电压范围是0－5V，若信号太小，必须进行放大；输入的模拟量在转换过程中应该保持不变，如若模拟量变化太快，则需在输入前增加采样保持电路。
地址输入和控制线：4条ALE为地址锁存允许输入线，高电平有效。
当ALE线为高电平时，地址锁存与译码器将A，B，C三条地址线的地址信号进行锁存，经译码后被选中的通道的模拟量进转换器进行转换。
A，B和C为地址输入线，用于选通IN0－IN7上的一路模拟量输入。
通道选择表如下表所示。

三、双向晶闸管输出接口
双向晶闸管具有双向导通功能，能在交流、 大电流场合使用，且开关无触点，因此在工业控 制领域有着极为广泛的应用。双向晶闸管隔离驱 动电路的设计是光耦合双向晶闸管驱动器。与一 般的光耦不同，在于其输出部分是一硅光敏双向 晶闸管，有的还带有过零触发检测器，以保证在 电压接近为零时触发晶闸管。
固态继电器由光电耦合电路、触发电路、开关电路、过零 控制电路和吸收电路五部分构成。这五部分被封装在一个 六面体外壳内，外面有四个引脚。非过零型SSR没有过零 控制电路。

直流型固态继电器主要用于直流大功率控制 场合。其输入端为一光电耦合电路，因此可用 OC门或晶体管直接驱动，驱动电流一般3～ 30mA，输入电压为5～30V，其输出端为晶 体管输出，输出电压30～180V。

8.3 开关量接口
开关量的输入与输出，CPU通过对输入信息分析是 “1”还是“0”，即可知开关是合上还是断开。如果控 制某个执行器的工作状态，只需送出“0”或“1”，即 可由操作机构执行。但是由于工业现场存在着电、磁、 振动、温度等各种干扰及各类执行器所要求的开关电 压量级及功率不同，所以在接口电路中需要选用不同 的元器件，还需要采用各种缓冲、隔离与驱动措施。

8.3.2 开关量输出接口
一、输出接口的隔离
VC
J
光耦合器是以光为媒介传输信号的器件，它把一个发光二极 管和一个光敏三极管封装在一个管壳内，发光二极管加上正 向输入电压信号（＞1.1V）就会发光，光信号作用在光敏三 极管基极产生基极光电流使三极管导通，输出电信号。
二、继电器输出接口
继电器输出，可完成从低压直流到高压交流的过 渡。在经光耦合器光电隔离后，直流部分给继电 器控制线圈供电，而其输出触点则可直接于 220V相接。
