GE-MK6E IS200TTURH1B
The General Electric IS200TTURH1B (TTUR) is a Primary Turbine Protection Input terminal board for GE SPEEDTRONIC™ Mark VI turbine control systems, working with the IS200VTUR board. It supports 12 passive pulse-rate devices sensing a toothed wheel to measure turbine speed, generator and bus voltage signals from potential transformers, a 125 V dc output to the main breaker coil for automatic generator synchronizing, and inputs from shaft voltage/current sensors.
TTUR includes three relays (K25, K25P, K25A) that must all close to energize the main breaker (52G). The speed-signal cable to VTUR uses the JR5 connector, and other signals use JR1; in TMR systems, signals fan out to JR5/JS5/JT5 and JR1/JS1/JT1. Note: TTURH1B does not support Mark VIe I/O packs.
For maintenance and procurement teams, IS200TTURH1B should be matched to the existing VTUR board and redundancy 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.
