P0916BX  通信输入模块   独立隔离模拟输入通道

PO916FL FOXBORO产品参数

测量范围:0-1000kPa

输出信号:4-20mA

精度等级:0.1%

工作温度:-40°C至85°C

供电电压:12-36VDC

概述

该PO916FL HART通信输入模块包含8个4至20 mA独立隔离模拟输入通道。它支持标准4-20 mA器件和HART器件的任意组合。

该PO916FL 作为HART通信现场设备主机，使Foxboro EVOTM系统请求和接收来自现场设备每秒两个数字消息。消息传递功能可用于支持HART通用、通用和设备特定的命令，但不支持突发通信模式。

智能现场设备配置器FoxcomTM和HARTTM协议(IFDC-有关详细信息，请参阅PSS21S-8A3 B3)。

该PO916FL 提供单独隔离的电源供应器，以权力的八个通道。

可选地，这两个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防止HART通信通道串扰。

summarize

The PO916FL HART communication input module consists of eight independently isolated analog input channels from 4 to 20 mA. It supports any combination of standard 4-20 mA devices and HART devices.

The PO916FL serves as the HART communication field device host, enabling the Foxboro EVOTM system to request and receive two digital messages per second from field devices. The messaging function can be used to support HART generic, generic, and device-specific commands, but does not support burst communication modes.

Intelligent field device Configurator FoxcomTM and HARTTM protocols (IFDC- For more information, see PSS21S-8A3 B3).

The PO916FL offers a separate isolated power supply to power eight channels.

Optionally, the channels for both modules can be powered by an external power supply

However, when a common external power supply is used for two or more channels, a cable-Barron module is required to prevent crosstalk in HART communication channels.
