The module operates primarily as a digital I/O termination unit and relay output board. It functions as a communication interface or bridge that routes control signals and handles data acquisition between an ABB INFI 90 OPEN multifunction processor and low-voltage field hardware like circuit breakers, actuators, or external relays.
It is engineered explicitly for ABB Bailey INFI 90 control systems, but it is also backward compatible or integrated within updated Symphony Plus architectures utilizing standard Bailey termination styling.
It features optical isolation across channels rated at 2500 VDC. This protects fragile core control electronics from high-voltage transients or ground loops generated out in the industrial field environment.
