FOXBORO P0500RQ 输入接口模块

紧凑型 P0500RQ 可用作HART通信现场设备主机，支持Foxboro DCS每秒请求和接收两条数字信息从现场设备。

The Compact P0500RQ can be used as a HART-communicating field device host to support Foxboro DCS requesting and receiving two digital messages per second from field devices.

P0500RQ 消息传递功能可用干支持HART通用，通用和设备专用命今，但它不能支持空发通信模式，这些命今是使用foxboro DCS HART现场设备专家。

P0500RQ The messaging feature can be used to dry support HART generic, general purpose, and device-specific propositions, but it cannot support the null-transmit communication modes that are used with the foxboro DCS HART Field Device Specialist.

P0500RQ 为上的现场设备提供独立的隔离电源八个频道中的每一个。可选地，输入通道可以由外部电源供电。然而，当公共外部电源用于两个或多个通道时，电缆巴伦模块有助于防止HART通信通道串扰 

P0500RQ Provide separate isolated power supplies for each of the eight channels for the field devices on. Optionally, the input channels can be powered by an external power supply. However, when a common external power supply is used for two or more channels, the Cable Barron module helps prevent crosstalk on the HART communication channels.
