Product Overview
This emergency trip board provides hardware-based overspeed protection for turbine systems. You can install GE IS200TREGH1BEC IS200TREGH1B directly into the Mark VIe rack. The unit monitors speed signals from multiple magnetic pickups simultaneously. It initiates a fuel shutdown immediately upon detecting unsafe conditions.

Board Layout and Components
The PCB dedicates separate signal conditioning circuits for each speed input. Three independent comparators evaluate frequency against programmable setpoints. Moreover, 128 discrete components handle signal filtering and logic decision-making. A redundant relay output provides positive fuel valve control. Consequently, the system initiates shutdown even during processor faults.
Installation Process
You can mount GE IS200TREGH1BEC IS200TREGH1B securely into Mark VIe rack slots. The three BNC connectors accept coax cables from magnetic pickups. Furthermore, terminal blocks provide connection points for the shunt trip relays. Clearly labeled jumpers allow configuration of trip setpoints.
Performance Advantages
This board responds to overspeed conditions in less than 15 milliseconds. Each speed channel operates independently from the main processor. Therefore, a processor failure does not disable the trip function. The redundant relay design also increases overall system safety integrity.
Safety and Compliance
GE IS200TREGH1BEC IS200TREGH1B meets SIL 2 and CE safety standards. The board self-discharges stored energy below 5V within five seconds. Hence, technicians face minimal electrical risk during maintenance procedures.
