Primary Application
Features:
- Turbine emergency trip terminal block
- Mark VIe series GE Energy IS200 Normal Assembly
- A dedicated hardware interface layer in the Mark VIe Speedtronic control system
The core function of this terminal board is to receive critical safety monitoring signals from the turbine unit (such as turbine speed and emergency stop commands), and upon detecting abnormal operating conditions that endanger equipment safety, quickly execute trip outputs to urgently stop the unit, thus providing comprehensive overspeed and emergency safety protection.
The IS200TREAH1A features high interface integration and fault tolerance. It is equipped with two 24-point pluggable isolation terminals for connecting external user signals and supports connection to nine passive pulse rate sensors (MPUs) to accurately monitor turbine speed by measuring the mechanical rotation of the rotor gears.
The IS200TREAH1A GENERAL ELECTRIC Turbine Emergency Trip Terminal Board may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
In terms of operating principle, the IS200TREAH1A employs a three-module redundancy (TMR) voting mechanism and electromagnetic induction technology to ensure high tripping reliability. Its connected passive pulse frequency sensor generates a high-frequency electrical signal by measuring the rotation of the turbine gears.
The IS200TREAH1A serves as the main interface panel, integrating physical safety field inputs and an emergency trip actuator.
It is designed to perform the following critical operations: Emergency turbine protection: As the terminal landing zone for the emergency trip solenoid valve and emergency stop circuit, it can cut off the fuel or steam supply in hazardous operating conditions.
Overspeed protection: It processes high-speed shaft speed signals to safely calculate and trigger a rapid release trip when the turbine exceeds its mechanical speed limits.
Hazardous environment deployment: It is officially certified for ATEX Zone 2 and Class I Zone 2 hazardous work spaces and can be directly installed in a distribution box near the turbine.
