Foxboro FBM242 16 Channel Isolated Output Module

Foxboro FBM242 is a 16-channel isolated output module with switch outputs that are driven by an external source. Each of the 16 channels is electrically isolated from the others and from the controller, providing independent switching capability for multiple external signals within a single module. The EXT. SOURCE designation indicates that the switch function for each channel is controlled by an external input, enabling externally supplied control signals to operate the outputs without sharing a drive path through the same source. This configuration aligns with industrial automation practices where isolation between control logic and switched outputs helps reduce interference and compatibility issues across multiple channels, all packaged within a Foxboro system framework.
