FBM204-P0914SY 输入/输出模块  提供转换时间和变化率限制的可配置选项

概述

FBM204-P0914SY,0至20ma输入/输出模块包含4个0至20ma直流模拟输入通道和4个0至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20 mA源。每个输出通道驱动一个外部负载，并产生一个0到20毫安输出。输入/输出与其他通道和地电隔离。FBM204执行从现场传感器到可选冗余现场总线的电气输入/输出信号接口所需的信号转换。

FBM204-P0914SY执行模拟I/O应用程序，它提供以下可配置选项: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)。当与v /A系列@软件v8.6至v8.8或Foxboro EvoTMControl核心服务软件v9.0或更高版本一起使用时，fbm可能会执行分布式PIDA (DPIDA)应用程序，以提供快速的控制环。

summarize

The FBM204-P0914SY,0 to 20ma input/output module contains four 0 to 20ma DC analog input channels and four 0 to 20ma DC analog output channels. Each input channel accepts analog sensor input, such as a 4 to 20 mA transmitter, or a self-powered 20 mA source. Each output channel drives an external load and produces a 0 to 20 mA output. Input/output isolated from other channels and ground electricity. The FBM204 performs the required signal conversion from the field sensor to the electrical input/output signal interface of the optional redundant fieldbus.

The FBM204-P0914SY performs an analog I/O application, which provides the following configurable options: conversion time, fail-safe configuration (hold/rollback) and analog output fail-safe rollback data (on a per-channel basis). When used with v /A Series @ software v8.6 to v8.8 or Foxboro EvoTMControl Core Service software v9.0 or later, fbm may execute a distributed PIDA (DPIDA) application to provide a fast control loop.

The FBM204 is electrically compatible with standard dhart signals

peculiarity

The main features of the FBM204 are:

Four 20ma DC analog input channels

Four 20ma DC analog output channels

Each input and output channel is electrically isolated

Rugged design for enclosures in G3(harsh) environments

Execute an analog/output application with configurable options for conversion time and rate of change limits

High precision is achieved through sigma-delta data conversion on each channel

The Terminal Assembly (TAs) is used locally or remotely to connect field cabling to the FBM204TA for output bypass stations that maintain output during maintenance operations.

Supports DPIDA control blocks.
