IS200TPROH1B - TPRO Emergency Protection Terminal Board | GE Mark VI | B7B

The General Electric IS200TPROH1B (TPRO) is an Emergency Protection terminal board for GE SPEEDTRONIC™ Mark VI turbine control systems. It supplies the IS215VPRO emergency overspeed protection board with speed signals, temperature signals, generator voltage, and bus voltage, providing 3 passive speed pickup inputs, generator/bus voltage inputs, 3 thermocouple inputs, analog inputs, trip interlocks, and an emergency-stop input.

TPRO is part of an independent triple-redundant emergency overspeed and synchronization protection system, separate from the main turbine control, and works with the TREx (TREG, TREL, or TRES) and TRPx (TRPG, TRPL, or TRPS) terminal boards to trip the turbine's emergency solenoids. Note: TPRO does not support Mark VIe I/O packs.

For maintenance and procurement teams, IS200TPROH1B should be matched to the existing VPRO board and protection-system 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.
