Application Fields
The IS200TREGS1BEC is a critical safety component within the Speedtronic Mark VI architecture. Its primary applications include:
- Gas Turbine Emergency Shutdown (ESD) control
- Steam Turbine overspeed protection and trip systems
- High-pressure Fuel Shut-off Valve (FSV) management
- Industrial Power Plant safety instrumentation systems
- Coordination between the Control Core and the Hydraulic Trip Unit
Product Instructions
- Installation: Secure the TREG board in the turbine control cabinet. Ensure the 37-pin cables (J-connectors) are routed correctly to the R, S, and T control cores.
- Wiring: Connect the trip solenoid valves to the terminal blocks. Note that the IS200TREGS1BEC is typically used to drive the “Primary” or “Emergency” trip solenoids; verify the specific pinout for ETD (Emergency Trip Device) wiring.
- Power Supply: Connect the 125 VDC or 24 VDC power source. The board uses these rails to energize the trip solenoids when the protection logic is healthy.
- Testing: Before turbine startup, perform a “Trip Test” via the Mark VI Toolbox software. Observe the onboard relay LEDs to confirm that all three cores (R, S, and T) are correctly de-energizing the solenoids when a trip is simulated.
Product Q&A
Q: What is the primary function of the TREG board in the Mark VI? A: The TREG board is the final interface for the emergency trip solenoids. It receives commands from the Protection (P) core and the R, S, and T control cores to cut power to the valves, physically shutting down the turbine in the event of a fault.
Q: How does the IS200TREGS1BEC handle voting logic? A: It employs a 2-out-of-3 (2oo3) voting hardware configuration. If at least two out of the three control cores signal a trip, the board will interrupt the power to the solenoid valves, ensuring safety even if one core fails.
Q: What do the onboard fuses protect? A: The fuses on the TREG board protect the individual output circuits going to the solenoids. A blown fuse will prevent the solenoid from energizing, which usually results in a “Fail-Safe” trip of the system.
Q: Can this board be used in a Simplex (non-redundant) system? A: The TREG is specifically designed for TMR systems where safety redundancy is required. While technically possible to wire in simplex, it is standard practice to use it only in 2oo3 safety architectures.
