Ordering Code Breakdown (Tree View)
- IS200 = Mark VI series family
- TRPG = Trip Terminal Board for gas turbine
- H1 = TMR version with 3 voting relays per solenoid
- B = Functional revision
- CC = Coating option (conformal coating)
Board Versions – Easy Selection
- H1A and H1B: Three voting relays per trip solenoid. Use for TMR applications.
- H2A and H2B: One relay per trip solenoid. Use for simplex applications.
How It Works
- Three voting circuits hold nine magnetic relays.
- These relays connect to three trip solenoids (ETDs).
- TRPG and TREG work together to form the interface to ETDs.
- TRPG accepts inputs from eight flame detectors.
- Flame detectors use Geiger-Mueller type sensors.
Mark VI System Integration
- VTUR board interfaces with TRPG terminal board.
- Cables with molded plugs connect TRPG to the VME rack.
- The VME rack holds the VTUR board.
- Supports both simplex and TMR configurations.
Mark VIe System Integration
- PTUR packs on TTURH1C control the TRPG board.
- D-type connectors on TTURH1C connect to TRPG.
- I/O packs plug into TTURH1C as inputs.
- Supports both simplex and TMR systems.
Board Layout – Quick Tour
- Two large black terminal blocks on the left side.
- Each block has 24 silver terminals (total 48).
- Terminals numbered 1 to 24 and 25 to 48.
- Eight yellow capacitors in a vertical line at bottom center.
- Two rows of small white capacitors on bottom left (16 total).
- White block with 12 small ports on bottom right.
- Three white connectors below that (3 ports each).
- Three connector ports on the right border (vertical line).
- Each connector port has 37 female pins.
- Multiple small integrated circuits across the board.
Installation Guide
- Mount the terminal board in the designated rack.
- Connect cables with molded plugs to the VME rack.
- For Mark VIe systems, use TTURH1C with D-type connectors.
- Secure all connections firmly.
- Verify the board type matches your application (H1 for TMR, H2 for simplex).
Diagnostic Capabilities
- Voting circuits check relay health continuously.
- Flame detector inputs show real-time flame status.
- Trip solenoid feedback confirms operation.
- Use Mark VI control software for detailed diagnostics.
Compatibility

Professional FAQ
- Q: What is the difference between H1 and H2 versions?
- A: H1 has three voting relays per solenoid for TMR. H2 has one relay per solenoid for simplex.
- Q: Can I use IS200TRPGH1B in a Mark VIe system?
- A: Yes. Connect it to PTUR packs on TTURH1C using D-type connectors.
- Q: What happens if a voting relay fails?
- A: The other two relays continue working. The system keeps running safely.
- Practical tip from engineers:
- Always check the solenoid response time (0.1 sec L/R). Use correct 125V dc supply for proper operation.
- Selection guide for buyers:
- Choose IS200TRPGH1B for TMR gas turbine applications needing three solenoids.
- Need simplex? Select H2A or H2B version instead.
- Confirm your Mark VI system revision before ordering.
- Check flame detector compatibility. This board expects Geiger-Mueller type detectors at 335V dc.
- This board works in both Mark VI and Mark VIe. Verify your controller type (VTUR or PTUR).
