Description
Product Description
The IS200TRPGH2B is a GE Mark VI Speedtronic Primary Trip Terminal Board designed for gas turbine protection and trip-control applications. The TRPG board provides the interface between the turbine protection controller and the primary/emergency trip devices, including trip solenoids. The H2B version is a Simplex configuration and can also accept inputs from up to eight Geiger-Mueller flame detectors in applicable gas turbine systems. Documented board features include three relay interfaces for trip solenoids, two 24-position terminal blocks, a 37-pin JR1 cable connector, additional plug connectors, and conformal-coated circuitry.

FAQ
Q: What is the IS200TRPGH2B used for?
A: It is a Primary Trip Terminal Board used in GE Mark VI gas turbine control and protection systems.
Q: Is the IS200TRPGH2B a TMR board?
A: No. The H2B version is documented as a Simplex TRPG board. TMR applications require the appropriate redundant hardware configuration.
Q: How many trip solenoids does the board interface with?
A: The documented H2B configuration has three relay interfaces associated with three trip solenoids.
Q: Does the board support flame detectors?
A: Yes. Applicable configurations can accept signals from up to eight Geiger-Mueller flame detectors.
Q: What are the trip output ratings?
A: Documented output contact ratings include 125 VDC at 1 A or 24 VDC at 3 A. The actual connected load must remain within the applicable system design limits.
Q: Is IS200TRPGH2BDE a different board?
A: IS200TRPGH2BDE is associated with the IS200TRPGH2B assembly. For replacement, match the complete board identification, revision, connectors, and system application rather than relying only on the base model number.
Troubleshooting & Safety
- Confirm the complete IS200TRPGH2B / IS200TRPGH2BDE identification before replacement.
- Verify that the existing turbine architecture requires the Simplex H2B configuration.
- Check all terminal wiring against the original turbine drawings before reconnecting field circuits.
- Inspect the JR1 cable and J1–J5 connectors for bent pins, contamination, or loose connections.
- Verify the trip-solenoid supply and output circuits before commissioning.
- For flame-detector faults, inspect detector wiring and signal polarity in addition to the TRPG connections.
- Do not alter relay or terminal wiring without the approved turbine control documentation.
- De-energize and isolate the turbine control and trip circuits before removing or installing the board.
- Trip and control circuits can contain hazardous DC voltage. Follow site lockout/tagout procedures and verify safe voltage before servicing.
- Because this board participates in turbine protection, replacement hardware should match the approved system configuration and revision.
