GE IS200TREGH1BEC Product Description

The IS200TREGH1BEC is an emergency trip termination board for GE Mark VIe turbine safety control systems. This rack‑mounted PCB is the critical hardware interface for turbine emergency shutdown logic, driving three emergency trip solenoids under I/O controller supervision. It integrates multi‑group safety relays, fault feedback circuits and field wiring terminals, implementing triple‑modular redundant trip voting logic. It receives 28VDC control power, outputs drive signals to trip solenoids, feeds back relay status to the control system via IONet communication, and supports hard‑wired manual E‑stop functions for gas and steam turbine protection loops. Conformal‑coated construction ensures stable operation in high‑noise power‑plant cabinet environments.

Product Features

• Trip‑solenoid driving interface for three independent emergency trip solenoids, works paired with TRPG negative‑side termination board
• Multiple safety relays implementing TMR voting logic for emergency trip commands, improves safety integrity and fault tolerance
• Supports hard‑wired manual emergency stop (E‑STOP) input via current‑limited 28 VDC power bus
• Real‑time relay status monitoring, transmits trip source and hardware diagnostic data to controllers over IONet fieldbus
• On‑board fuses and surge suppression protect solenoid drive circuits against overcurrent and electrical transients
• Standard plug‑in rack‑mount design compatible with Mark VIe backplane, supports simplex and TMR redundant system architectures
• Conformal‑coated PCB variant, anti‑moisture and anti‑corrosion for power‑plant cabinet operating conditions
• Fast‑acting safety relays to ensure rapid turbine emergency shutdown response upon protection‑system triggers
