FBM216 P0917XQ   通信冗余输入接口模块  提供单独隔离的电源供应器

型号:FBM216 P0917XQ

通讯接口:RS-485

工作电压:24VDC

工作温度:-40℃℃~85℃℃

产品尺寸:107mmx70mmx25mm

概述

该FBM216 P0917XQ  HART通信冗余输入接口模块包含8个单独隔离的输入通道。它支持标准4到20 mA器件和HART器件的任意组合(信号是电兼容的)。

一对模块组合在一起提供现场总线模块(FBM)级冗余，现场输入连接到一个公共终端组件。在这种配置中，一个FBM216 P0917XQ是主控制器，另一个是跟踪器。

FBM216  P0917XQ可以作为HART通信现场设备主机，使Foxboro"DCS请求和接收来自现场设备的每秒两个数字消息。消息传递功能可用于支持HART通用、常用和设备特定的命令，但不能支持突发通信模式。这些命令是使用FoxboroDCS现场设备专家HART实现的。有关详细信息，请参阅HART设备控制的现场设备专家和输入/输出(PSS 41S-10FDMHRT)。

该FBM216 P0917XQ提供单独隔离的电源供应器，以权力的八个通道，

可选地，该模块的通道可以由外部电源供电。然而，当一个共同的外部电源用于两个或多个通道时，需要一个电缆巴伦模块来帮助防止HART通信通道串扰。

summarize

The FBM216 P0917XQ HART communication redundant input interface module contains eight individually isolated input channels. It supports any combination of standard 4 to 20 mA devices and HART devices (the signal is electrically compatible).

A pair of modules are combined to provide fieldbus module (FBM) level redundancy, with field inputs connected to a common terminal component (see Figure 1, page 4). In this configuration, one FBM216 P0917XQ is the primary controller and the other is the tracker.

The FBM216 P0917XQ can be used as a HART communication field device host, enabling Foxboro"DCS to request and receive two digital messages per second from field devices. The messaging function can be used to support HART generic, common, and device-specific commands, but cannot support burst communication modes. These commands were implemented using HART, a FoxboroDCS field equipment specialist. For more information, see the Field Equipment Expert and Input/Output for HART Device Control (PSS 41S-10FDMHRT).

The FBM216 P0917XQ offers individually isolated power supplies to power eight channels,

Optionally, the module's channels can be powered by an external power source. However, when a common external power supply is used for two or more channels, a cable-Barron module is needed to help prevent crosstalk in HART communication channels.
