IS200TRTDH1B - TRTD RTD Input Terminal Board | GE Mark VI | B7B

The General Electric IS200TRTDH1B (TRTD) is an RTD Input terminal board for GE SPEEDTRONIC™ Mark VI turbine control systems, accepting 16 three-wire RTD inputs wired to two barrier-type terminal blocks, with noise suppression circuitry to protect against surge and high-frequency noise.

TRTD communicates with one or more I/O processors that convert inputs to digital temperature values for the controller. IS200TRTDH1B is the TMR version of TRTD, fanning signals out to three IS200VRTD boards using six DC-type connectors; in Mark VI systems it works with the VRTD processor and supports TMR applications, connecting to three VRTD processors with six cables.

For maintenance and procurement teams, IS200TRTDH1B should be matched to the existing VRTD board generation 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.
