Description
🔹 Product Description
The GE IS200TRTDH1C, also identified as IS200TRTDH1CCC, is an RTD Input Termination Board designed for the GE Mark VI Speedtronic turbine control system. The TRTD board provides termination for 16 three-wire RTD inputs and connects these field temperature signals to the associated VRTD I/O processor through two DC-type connectors. The IS200TRTDH1C is the simplex version of the TRTD terminal board, making it suitable for Mark VI applications that do not require the redundant TMR configuration. The board includes two barrier-style terminal blocks, shield termination provisions, and signal-conditioning/noise-suppression circuitry for RTD measurement applications.

🔹 Q&A
Q: What is the GE IS200TRTDH1C used for?
A: It is used to terminate and interface RTD temperature sensor signals in a GE Mark VI turbine control system.
Q: How many RTD inputs does it support?
A: The IS200TRTDH1C supports 16 three-wire RTD inputs.
Q: Is IS200TRTDH1C a TMR board?
A: No. The H1C version is the simplex configuration. The H1B variant is associated with the TMR configuration.
Q: What board is associated with the TRTDH1C?
A: The TRTDH1C connects to the VRTD I/O processor through its DC-type connectors. The exact processor configuration depends on the Mark VI system architecture.
Q: What is the difference between IS200TRTDH1C and IS200TRTDH1B?
A: IS200TRTDH1C is a simplex RTD terminal configuration, while IS200TRTDH1B provides redundant RTD signal distribution for TMR Mark VI systems.
Q: Does the board require RTD wiring to be checked before replacement?
A: Yes. Confirm the RTD channel assignments, three-wire connections, shield wiring, connector positions, and controller configuration before removing or installing the board.
Q: Is IS200TRTDH1CCC the same ordering family as IS200TRTDH1C?
A: IS200TRTDH1CCC is an assembly-level identification associated with the IS200TRTDH1C board. Always compare the complete board identification and revision markings before replacement.
Q: Can this board be used in a Mark VI TMR system?
A: The H1C configuration is intended for simplex applications. A TMR system normally requires the appropriate H1B configuration.
