IS200TRTDH1C - TRTD RTD Input Terminal Board | GE Mark VI | B7B

The General Electric IS200TRTDH1C (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. IS200TRTDH1C is a simplex board with two DC-type connectors; in Mark VI systems it works with the IS200VRTD processor and supports simplex applications, connecting to VRTD with two cables.

For maintenance and procurement teams, IS200TRTDH1C should be matched to the existing VRTD board generation and redundancy configuration per GEH-6421 Volume II before ordering a replacement.
