FBM204系统备件库存模块 Foxboro

FBM204, 0至20 mA输入/输出包含4个20 mA直流模拟输入通道  和4个20ma直流模拟输出通道。  

每个输入通道接受模拟传感器输入，如4至20 mA发射机，  或自供电20ma电源。每个输出通道驱动一个外部负载和  产生0至20 mA输出。输入/输出是电隔离的  渠道和地面。  

FBM204执行电输入接口所需的信号转换  从现场传感器输出信号到可选的冗余现场总线的FBM204  执行模拟I/O应用程序，它提供以下功能  可配置选项:转换时间，故障安全配置(保持/回退)，和  模拟输出故障安全回退数据(以每个通道为基础)。现场总线模块  (FBM)可以执行分布式PIDA(DPIDA)应用程序来  提供一个快速的控制回路在其中运行。

The FBM204, 0 to 20ma input/output contains four 20 mA DC analog input channels and four 20 mA DC analog output channels.

Each input channel accepts analog sensor input, such as a 4 to 20ma transmitter, or a self-powered 20 mA power supply. Each output channel drives an external load and produces 0 to 20 mA output. The input/output is electrically isolated from the channel and ground.

The FBM204 performs signal conversion required by the electrical input interface from the field sensor output signal to the optional redundant fieldbus. The FBM204 performs analog I/O applications, which offer configurable options for the following functions: conversion time, fail-safe configuration (hold/rollback), And analog output fail-safe rollback data (on a per-channel basis). The Fieldbus module (FBM) can execute distributed PIDA(DPIDA) applications to provide a fast control loop to run in.
