The GE IS410STCIS2A / IS400STCIS2AFF is a Mark VIeS Simplex Contact Input (STCI) Terminal Board designed for 24 V DC discrete contact input applications. It provides the field-wiring interface between contact-based field devices and the GE Mark VIeS safety control architecture. The board supports 24 discrete input channels and is designed to work with the IS420YDIAS1B Contact Input Safety I/O Pack. The STCI configuration uses a simplex I/O architecture and provides signal termination, contact excitation, and noise suppression for industrial control and turbine safety applications. GE documentation specifies 24 V DC nominal contact-input wetting voltage, 24 input channels, DIN-rail mounting, and a 1 ms Sequence of Events sampling rate.
