The IS200PAOCH1B Turbine Protection Board is designed for use in the GE Speedtronic turbine control systems, specifically for gas and steam turbines. It is a part of the Mark VI series and provides critical protection to turbines by monitoring and controlling various parameters that can impact turbine safety and performance.

The IS200PAOCH1B board provides turbine protection, especially against over-speed, over-temperature, and other safety-critical parameters that could lead to turbine damage or failure.

IS200PAOCH1B It utilizes a triple modular redundancy (TMR) system for fail-safe operation, ensuring that turbine protection remains active even if one board fails.

IS200PAOCH1B  It typically includes multiple inputs for temperature and pressure sensors, as well as outputs to control trip solenoids and other emergency systems.

The IS200PAOCH1B board operates with 125 V DC power supply and is housed in a rugged surface mount technology (SMT) design for high reliability and long-term operation.

IS200PAOCH1B It is designed to operate within a temperature range of -30°C to 65°C.

The IS200PAOCH1B is typically used in conjunction with other modules like TREG and TRPG boards to offer full emergency turbine protection, including emergency overspeed (EOS) and trip solenoid management. 

The IS200PAOCH1B board is engineered for easy integration into existing turbine protection systems and can handle both real-time monitoring and emergency shutdown functionalities.

The GE IS200PAOCH1B Turbine Protection Board is an advanced protection module designed for turbine control systems, particularly useful in gas and steam turbines. This board provides essential safety features, ensuring the turbine operates efficiently and securely by monitoring critical parameters.

The IS200PAOCH1B offers a high level of accuracy with a pulse rate range from 2 Hz to 20 kHz, ensuring precise turbine speed monitoring.

The IS200PAOCH1B module is equipped with 3 trip solenoids, which trigger safety measures in the event of operational irregularities.

This IS200PAOCH1B board monitors contact voltage levels, with 20 V DC for high voltage and 6 V DC for low voltage, ensuring safety thresholds are maintained.
