FBM240-P0917GZ  现场总线模块  单个或冗余模块

型号：FBM240-P0917GZ

紧凑型FBM240-P0917GZ是一个8通道输入和8通道输出Foxboro™DCS

现场总线模块(FBM)可用作单个或冗余模块。冗余对这些模块组合在一起，在FBM级别提供冗余，并连接到现场I/O

一个公共终端组件(见图1)。每个模块独立持有在其指定的输出值处输出，并且每个都独立地读取其

输出的观测值。

该模块是Compact 200系列I/O子系统的一部分200系列I/O子系统概述(PSS 41H-2COV)。控制软件中的冗余触点输出块验证中的每个输出与输入/输出模块的信息相结合。8个分立输出/ 8个分立电压监视器输入

•8个离散输入读取继电器触点的电压。设置如果连接的状态与通道的状态不一致，则打开通道BAD相应输出通道

•监控每个FBM输出和设置输出通道BAD，如果输出是在错误的状态

•单个或冗余模块

•终端组件(TAs)用于本地或远程连接现场布线到紧凑FBM240

•支持能够切换的离散继电器输出:

◦10a在80至120v ac，或

◦在80至125 V直流5 A，或

◦电压为15 ~ 30v dc，电压为5a

◦5 A, 80 ~ 120v ac

•支持通道隔离的离散I/O:

◦15-60 V dc @ 2a，熔融输出

◦15- 60v直流输入

注意:支持此终止程序集和新的Fail-Safe

第6页Fail-Safe中描述的配置选项需要版本1.40N或

以后的固件。

•冗余操作故障检测

输出触点监视器读回和内部FBM检测的高覆盖率故障允许冗余合作伙伴自动继续驱动离散输出和监控输入

•内部每通道输出需求状态故障检测

◦输出通道被标记为坏在单和冗余操作，如果需求状态回读表示未比较状态

Model: FBM240-P0917GZ

The compact FBM240-P0917GZ is an 8-channel input and 8-channel output Foxboro™DCS

Fieldbus modules (FBMS) can be used as single or redundant modules. Redundancy The modules are grouped together to provide redundancy at the FBM level and to connect to field I/O

A common terminal component (see Figure 1). Each module independently holds the output at its specified output value, and each reads it independently

The output observations.

This module is part of the Compact 200 Series I/O Subsystem Overview of the 200 Series I/O Subsystem (PSS 41H-2COV). Each output in a redundant contact output block verification in the control software is combined with information from the input/output module. 8 discrete outputs / 8 discrete voltage monitor inputs

•8 discrete inputs read the voltage of relay contacts. Set If the status of the connection is inconsistent with the status of the channel, open the corresponding output channel of channel BAD

Monitor each FBM output and set the output channel BAD if the output is in the wrong state

• Single or redundant modules

• Terminal Components (TAs) are used for local or remote connection of field cabling to the compact FBM240

• Supports discrete relay outputs that can be switched:

◦10a in 80 to 120v ac, or

◦ At 80 to 125 V DC 5 A, or

◦ The voltage is 15 to 30v dc and the voltage is 5a

◦5 A, 80 ~ 120v ac

Discrete I/O with channel isolation:

◦15-60 V DC-@ 2a, molten output

◦ 15-60 V DC input

Note: Support for this termination assembly and the new Fail-Safe

The configuration options described in Fail-Safe on page 6 require version 1.40N or

Future firmware.

• Detect redundant operation faults

High coverage failures for output contact monitor read back and internal FBM detection allow redundant partners to automatically continue driving discrete outputs and monitoring inputs

• Internal output requirement status fault detection for each channel

◦ The output channel is marked as bad in single and redundant operation, if the demand state is read back indicates no comparison state
