Part details:
GE-MK6 IS200VCRCH1A

The General Electric IS200VCRCH1A (VCRC) is a Discrete Input/Output board for GE SPEEDTRONIC™ Mark VI turbine control systems, accepting 48 discrete contact inputs and controlling 24 relay outputs from up to four terminal boards (IS200TBCI and TRLY).

VCRC is a single VME-slot board offering the same functionality as the two-slot IS200VCCC board, using front-panel connectors J33/J44 for contact input cabling (in place of the VCCC's daughterboard) while relay outputs on TRLY use the same J3/J4 VME rack connectors as VCCC. Contact inputs are optically isolated and sampled at the frame rate for control, and at 1 ms for sequence-of-events (SOE) recording. Note: VCRC does not support the TICI contact-voltage-sensing terminal board.

For maintenance and procurement teams, IS200VCRCH1A should be matched to the existing terminal-board cabling (TBCI/TRLY) and application configuration per GEH-6421 Volume II before ordering a replacement.

Control system parts are provided by GTC Control Solutions, Inc., a wholly owned subsidiary of B7B. Parts are offered in unused, repaired, or remanufactured condition, subject to availability. Each repaired or remanufactured component undergoes functional testing in energized panels, with test reporting and warranty support provided for repair and lifecycle-extension programs.
