PRODUCT INFORMATION
Product Overview
The General Electric IS200TRPGH1B is a primary trip terminal board for Mark VI and Mark VIe turbine control systems. This board interfaces with turbine protection relays to drive up to three electrical trip devices. It incorporates three voting relays per trip solenoid to support Triple Modular Redundant configurations. It also accepts inputs from up to eight Geiger-Mueller flame detectors in gas turbine operations.
During standard operation, the unit cooperates with the emergency trip board to provide system shutdown capability. Internal relay ladder logic provides hardware two-out-of-three voting for the protection solenoids. The I/O controller monitors relay coil driver current lines and contact health continuously. Connectors include onboard electronic identification devices to prevent hardware mismatch faults during installation.

- J3, J4, and J5 connectors deliver operating power to the flame detection channels.
- JR1, JS1, and JT1 connectors interface with I/O controllers and contain diagnostic ID chips.
TECHNICAL INFORMATION
Installation Guidelines
- Mount the terminal board in the designated control enclosure according to GEH-6421J manual instructions.
- Connect trip solenoid field wiring directly to the first terminal block.
- Terminate flame detector signal wiring at the dedicated second terminal block.
- Confirm connector cables with molded plugs seat securely into JR1, JS1, and JT1 sockets.
TECHNICAL INFORMATION
Configuration Guidelines
- Verify that the system architecture matches the H1B hardware group configured for TMR voting operation.
- Ensure the matching I/O processor correctly reads the electronic ID devices on the board connectors.
- Configure flame detector channel thresholds within the Mark VI or Mark VIe engineering workstation software.
TECHNICAL INFORMATION
Compatibility
- General Electric Mark VI systems using the VTUR turbine interface board within a VME chassis.
- General Electric Mark VIe systems using PTUR I/O packs mounted on TTURH1C terminal assemblies.
- General Electric TREG terminal boards for combined primary and emergency trip interface operation.
TECHNICAL INFORMATION
Lifecycle / Replacement Information
- The IS200TRPGH1B serves as the TMR-configured hardware group within the TRPG primary trip board series.
- Group H1B uses three voting relays per solenoid and cannot directly replace simplex H2A or H2B models.
- Hardware replacement requires matching the terminal board revision ID chip queried by system diagnostics.
