Command – Control Device MMI (Man Machine Interface)

MAN MACHINE INTERFACE
MMI system, developed in the factory SIGMA from Subotica, is the interface between relay and electronic equipment. MMI system is used for monitoring of condition and work of indoor relay devices, devices of APB and related devices of level crossing, also for creating connection between these devices and computer system. MMI interface is used for galvanic separation of the signal from indoor relay devices and the acceptance of commands from computer device to indoor relay device by which it completely replaces features of coomand relay panel in mosaic technique.
