IS200TBCIH2CCD Contact Input Terminal Board

The GE IS200TBCIH2CCD is a Contact Input Terminal Board (TBCI) designed for the Speedtronic Mark VI and Mark VIe turbine control systems. Its core function is to serve as the physical interface between field dry-contact devices—such as limit switches, pressure switches, and trip buttons—and the Mark VIe control system. It provides signal conditioning, group isolation, and surge protection for up to 24 discrete dry contact inputs before routing the signals to the associated I/O pack.
