GE IS200SPIDG1ABA is a Servo I/O (SPID) module for the GE Mark VI turbine control system. It interfaces turbine control electronics with hydraulic servo valve actuators, enabling precise control of turbine hydraulic systems. The module conditions command signals from the controller, drives servo valves with accurate current outputs, and monitors feedback signals for closed-loop control. Designed for gas and steam turbines, it ensures reliable operation in power generation, oil & gas, marine propulsion, and heavy industrial automation environments.
