The GE IS200WROBH1AAA is a specialized SRLY Option Board-B used within GE Mark VI and Mark VIe turbine control systems. It is designed as a high-reliability relay and power sensing printed circuit board (PCB), responsible for managing fused power distribution, relay switching logic, and signal feedback to the turbine control system.
In industrial power generation environments, this module ensures safe and stable operation of auxiliary control circuits by isolating field devices from sensitive control electronics. It is commonly used in gas and steam turbine systems where precise relay control and system protection are essential for continuous operation.
