Part details:
GE-MK6 IS200TBTCH1B

The General Electric IS200TBTCH1B (TBTC) is a Thermocouple Input terminal board for GE SPEEDTRONIC™ Mark VI turbine control systems, accepting 24 type E, J, K, S, or T thermocouple inputs wired to two barrier-type terminal blocks.

TBTC communicates with the I/O processor through DC-type connectors. IS200TBTCH1B is the TMR version, with six DC-type connectors, connecting to three IS200VTCC boards with six cables. In the Mark VI system, TBTC works with the VTCC thermocouple processor and supports both simplex and TMR applications.

For maintenance and procurement teams, IS200TBTCH1B should be matched to the existing VTCC 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.
