FOXBORO FBM201D FBM201E Product Brief Description

The FOXBORO FBM201D is a 200-series 8-channel galvanically isolated DC voltage analog input fieldbus module for Foxboro I/A Series DCS. It is the 0~10VDC variant of the FBM201 family, designed to acquire self-powered voltage transmitter and potentiometer signals. It uses sigma-delta A/D conversion, supports HART signal compatibility, and communicates with FCP/FCM controllers via redundant 2Mbps fieldbus for high reliable analog voltage measurement.
