Product Details

The IS200TRLYH1BGF is TRLY series triplicated relay output terminal board for GE Speedtronic Mark VI turbine control system.

This VME rack‑mounted board adopts plug‑gable magnetic relay design, 12 independent Form‑C SPDT relay channels are available for safety‑critical loop control. It supports jumper configuration for multiple field working voltages, adapts to various turbine trip circuit requirements. The unique coil‑sensing circuit can detect relay coil excitation abnormity, upload fault diagnosis information to controller. Each channel is equipped with LED indicator for convenient on‑site inspection and fault troubleshooting. BGF conformal coating enhances moisture‑proof, dust‑proof and anti‑corrosion performance, effectively resists voltage surge and electromagnetic interference from field cables.

It supports simplex and TMR triple‑modular redundant system configuration, widely applied for emergency shutdown protection of gas‑steam turbo‑generator units.

It belongs to safety‑critical spare‑part for Mark VI turbine control system, widely used in overhaul and renovation projects of power generation units.

It is important spare hardware for turbine safety trip loop debugging and defective IS200TRLYH1BGF board replacement.
