The IS230TRPA1AG01 is a Turbine Primary Trip Terminal Board developed for use within GE’s Mark VIe turbine control systems. This critical component is engineered to ensure rapid and secure disconnection of the turbine during abnormal operating conditions, acting as a frontline interface between the turbine control logic and the field trip devices.

This board forms part of the emergency trip system, a vital safety feature for any turbine-driven application. It accepts trip signals from the Mark VIe controller and routes them to the electrohydraulic trip solenoids, which in turn trigger the shutdown of fuel, steam, or air supplies to the turbine. With robust fault-tolerant architecture, the IS230TRPA1AG01 is built to operate reliably in high-stakes environments where safety and speed are paramount.

The terminal board supports multiple trip outputs and includes redundant paths to ensure tripping action is successful even if a failure occurs in one path. Additionally, it features feedback channels that confirm whether trip signals have been executed correctly, supporting improved diagnostics and safety validation in real time.

For connection to the control system, the board uses screw-type terminals for secure field wiring. Its DIN rail mounting design allows for compact and easy installation inside turbine control panels. Integration with compatible I/O packs, such as the IS220PTURH1A, enables high-speed logic control and monitoring of trip functions.

Engineered to comply with stringent industrial and utility-grade safety standards, the IS230TRPA1AG01 provides critical over-speed, over-temperature, and emergency shutdown protection for gas and steam turbines. Its rugged design allows operation in extreme temperature and vibration conditions, making it ideal for power plants and heavy industrial sites.

The board’s role in maintaining safe turbine operations cannot be overstated. In events such as control failure, hydraulic failure, or emergency shutdown commands, this board ensures that the turbine shuts down quickly and safely—protecting both equipment and personnel.

Key Features:

• Interfaces with turbine trip solenoids

• Supports redundant trip paths for safety

• Feedback verification of trip execution

• DIN rail mountable for easy installation

• Works with Mark VIe I/O modules like IS220PTURH1A
