GE Mark VIe IS200STCIH2ADD Single Channel Contact Input Terminal Board

GE Mark VIe IS200STCIH2ADD Single Channel Contact Input Terminal Board

IS200STCIH2ADD is a single channel contact input terminal board (STCI) for GE Speedtronic Mark VIe turbine control system, used in conjunction with PDIA digital processing I/O card, and belongs to the switch signal front-end interface board.
The core function of IS200STCIH2ADD is to collect on-site dry contact signals, such as circuit breaker auxiliary contacts, isolation switch positions, local emergency stop buttons, limit switches, relay status and other discrete signals, to complete signal filtering, surge suppression, excitation voltage distribution, and transmit the conditioned switch signals to PDIA cards for logical operations; Provide reliable switch quantity acquisition channels for unit interlocking, trip circuits, and status feedback. IS200STCIH2ADD is an important signal access board for the protection and sequential control circuits of gas turbines and steam turbines.
