FOXBORO FBM223 福克斯波罗I/A Series系统

FOXBORO FBM223 福克斯波罗I/A Series系统

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。

FBM204与标准hart信号在电气上兼容。

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

And 4 20ma DC analog output channels.

Each input channel accepts analog sensor inputs, such as 4 to 20 mA transmitters,

Or self-powered 20ma power supply. Each output channel drives an external load and

Produces 0 to 20 mA output. The input/output is electrically isolated

Channels and ground.

The FBM204 performs the signal conversion required by the electrical input interface

Output signals from field sensors to optional redundant fieldbuses. The FBM204

Execute the emulated I/O application, which provides the following functions

Configurable options: conversion time, fail-safe configuration (hold/rollback), and

Analog output fail-safe rollback data (on a per-channel basis). Fieldbus module

(FBM) can execute distributed PIDA (DPIDA) applications

Provides a fast control loop in which to run.

The FBM204 is electrically compatible with standard hart signals.
