FBM207/b/c电压监测仪/接触感测输入模块功能为16路直流电压监测仪或16路接触传感器。每个通道接受来自直流电压源(FBM207)或对触点或固态开关(FBM207b/ FBM207c)的2线输入。相关终端组件(TAs)支持60v DC、120v AC/ 125v DC或240v AC电压下的离散输入信号。对于高于60vDC的电压，TAs具有额外的信号调理硬件，提供电压衰减和光隔离。每个离散输入与其他通道和地电隔离。组隔离时，使用外部激励。

该模块执行从现场传感器到冗余模块现场总线的电气输入信号接口所需的信号转换。此外，它还执行离散输入，梯形逻辑，脉冲计数和事件序列的程序，并具有输入滤波器时间的可配置选项。该模块可以用作单个单元，也可以用作冗余对(两个fbm207)。当作为冗余对使用时，这些模块结合起来在现场总线模块(FBM)级别提供冗余，现场输入信号通过一个附加在FBM底板上的冗余适配器从一个公共终端组件接收。冗余模块的输入电流增加一倍。Foxboro Evo”M控制软件中的冗余数字输入块与模块的信息一起验证每个输入，并选择控制策略中处理质量最高的输入。在冗余配置中，来自每个模块的接触感测功率在冗余适配器中二极管或一起，以确保冗余功率。

The FBM207/b/c voltage monitor/contact sensing input module has a function of 16 DC voltage monitors or 16 contact sensors. Each channel receives a 2-wire input from a DC voltage source (FBM207) or from a contact or solid-state switch (FBM207b/FBM207c). The relevant terminal components (TAs) support discrete input signals at 60v DC, 120v AC/125v DC, or 240v AC voltages. For voltages above 60vDC, TAs have additional signal conditioning hardware to provide voltage attenuation and optical isolation. Each discrete input is isolated from other channels and ground currents. When isolating groups, external incentives are used.

This module performs the signal conversion required for the electrical input signal interface from the field sensor to the redundant module fieldbus. In addition, it also executes programs for discrete inputs, ladder logic, pulse counting, and event sequences, and has configurable options for input filter time. This module can be used as a single unit or as a redundant pair (two FBM207). When used as redundant pairs, these modules are combined to provide redundancy at the Field Bus Module (FBM) level, where the field input signals are received from a common terminal component through a redundant adapter attached to the FBM backplane. Double the input current of the redundant module. The redundant digital input blocks in Foxboro Evo “M control software validate each input along with the module’s information, and select the input with the highest processing quality in the control strategy. In redundant configurations, the contact sensing power from each module is diode or together in the redundant adapter to ensure redundant power.

PLC内的I/O模板，除一般的DI/DO、AD/DA模板外，还发展了一系列特殊功能的I/O模板，这为PLC用于各行各业打开了出路，如用于条形码识别的ASCII/BASIC模板，用于反馈控制的PID模板，用于运行控制、机械加工的高速计数模板、单轴位置控制模板、双轴位置控制模板、凸轮定位器模板、射频识别接口模板等，这在以后还会有很大发展。另外在输入、输出的相关元件、强干扰场合的输入、输出电隔离、地隔离等方面也会更加完善。
