Foxboro FBM214 P0922VT HART Communication Input Interface Module

Overview

The Foxboro FBM214 P0922VT is a HART communication input interface module. It offers eight analog input channels for industrial automation. Each channel handles 4-20 mA analog or digital HART signals superimposed on the analog input. The module enables bi-directional communication with field devices using dedicated FSK modems. It supports two digital messages per second, ensuring efficient data exchange.
