Description
GE IS200SRTDH2ACB is a specialized Resistance Temperature Detector (RTD) input terminal board engineered specifically for the General Electric Mark VI and Mark VIe gas and steam turbine control systems. Designed to terminate, condition, and route temperature sensor signals from the field to system I/O modules, this board ensures high-precision thermal monitoring across heavy-duty power generation and industrial automation architectures.

Operating Guidelines and Usage Methods
Proper integration and handling of thermal input terminal boards require strict adherence to instrumentation wiring and electrical safety standards.
- ESD Precautions: Always wear a certified grounded electrostatic discharge (ESD) wrist strap when handling associated electronic I/O packs to protect sensitive internal microcircuits from static damage.
- Terminal Wiring: Ensure all incoming field RTD sensor wires are securely terminated to the proper screw or clamp blocks, carefully observing correct lead compensation and wiring configurations (especially for 3-wire loops).
- Shield Grounding: Terminate overall cable shields securely to the designated chassis grounding bars to prevent electrical noise and electromagnetic interference (EMI) from skewing temperature readings.
Power-On and Power-Off Sequence
Adhering to correct energization protocols prevents signal transients and protects analog measurement circuitry within the Mark VI/VIe architecture.
- Power-On Sequence:
- Confirm that all field RTD wiring and backplane connectors are correctly and securely terminated to the IS200SRTDH2ACB board.
- Plug the compatible Mark VIe temperature input I/O pack firmly into the board interface and secure the locking mechanisms.
- Switch on the primary cabinet power distribution feeds and check operator workstation software to confirm normal module communication and channel status.
- Power-Off Sequence:
- Safely take the affected temperature monitoring loops offline via the operator workstation software.
- Power down the system rack distribution feeds if complete electrical isolation is required prior to maintenance.
- Allow circuits to de-energize before unseating the plug-in I/O pack from the terminal board.
Product Instructions
The terminal board serves as the permanent mechanical and electrical termination point for field temperature detectors, routing conditioned analog millivolt signals to the plugged I/O pack for processing. Perform routine inspections of terminal screw torques and wiring harnesses during scheduled maintenance windows to prevent loose connections or measurement drift.
Frequently Asked Questions (Q&A)
- Q: What system is the IS200SRTDH2ACB board designed for?
- A: It is utilized as a core RTD temperature input termination module within the GE Mark VI and Mark VIe distributed control architecture.
- Q: Can the plugged I/O pack be replaced without disconnecting field wiring?
- A: Yes, the modular design allows the electronic I/O pack to be removed or replaced without disturbing the field sensor wires attached to the terminal board blocks.
- Q: What should I check first if a temperature channel reports erratic or open-circuit values?
- A: Verify field wiring and terminal tightness, inspect sensor lead continuity, and ensure the paired I/O pack is securely seated.
