The IS200TRPGH1B is a primary trip terminal board for General Electric Mark VI gas turbine control systems. It features 8 flame detector inputs (335 V dc supply), 28 V DC control relay supply, and 0.1 sec L/R solenoid response time. (PSFD).
- Terminal Board
- The H1A and H1B versions include three voting relays built into each trip solenoid for TMR applications
- For simplex applications, the H2A and H2B versions have one relay per trip solenoid
IS200TRPGH1B is a Primary Trip Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in gas turbine controI systems. The I/O controller regulates the TRPG terminal board. Three voting circuits in TRPG feature nine magnetic relays that connect to three trip solenoids, or Electrical Trip Devices (ETD).

This circuit board is mainly used for turbine protection systems, responsible for connecting the control system with emergency protection devices on site, ensuring quick and accurate tripping (cutting off) operations in emergency situations. Trip solenoid valve interface: Supports up to 3 trip solenoid valves (ETDs), with 3 voting circuits composed of 9 internal magnetic relays to achieve high reliability triple redundancy (TMR) control.
Flame detection interface: can supply power and receive signals for up to 8 Geiger Mueller flame detectors, used for real-time monitoring of the combustion status of turbines. Fast response: Its solenoid valve response time (L/R time constant) is only 0.1 seconds, ensuring extremely high safety.
The IS200TRPGH1B trip terminal board achieves excellent internal equipment protection through highly integrated hardware redundancy and self diagnostic mechanism:
it not only carries the key physical interface of the emergency trip circuit of the turbine, but also embeds complex triple redundancy (TMR) logic voting function in the internal circuit, which can monitor the status of the hydraulic solenoid valve on site in real time and provide comprehensive electrical isolation protection against overcurrent, short circuit and wire breakage, ensuring that even in the case of single channel control failure or external wiring failure, it can accurately trigger safety shutdown instructions through robust hardware relay logic, effectively preventing turbine overspeed or mechanical damage in extreme working conditions, and building the last line of defense for safe operation of the unit.
