Foxboro FBM207 P0914TD Channel Isolated 16 DIN Voltage Monitor

The FBM207 P0914TD is a 16-channel DC voltage monitoring module that supports channel isolation and monitors multiple voltage levels. Each channel independently accepts input from either a DC voltage source or a switch sensor.

Key Features

Channel Isolation: Each of the 16 channels is isolated and independent.
DC Voltage Monitoring: Capable of monitoring 60 V DC, 120 V AC/125 V DC, and 240 V AC.
Switch Inputs: Supports external 120 V AC/125 V DC and 240 V AC switch inputs.
Communication: Communicates with associated FCM or FCP via redundant 2 Mbps Fieldbus.
