Description
1. Product Title
GE IS200TSVCH1AJE – Servo Valve I/O Terminal Board
2. Product Overview
The GE IS200TSVCH1AJE is a servo input/output terminal board from GE’s Mark VI turbine control system series. It provides high-density termination and signal conditioning for servo valves, LVDTs, and position feedback devices used in precise actuator control loops. This board resolves interface challenges between controllers and hydraulic/pneumatic servos by offering jumper-configurable current outputs, voltage references, and feedback amplification, ensuring stable closed-loop regulation. Designed for simplex and TMR redundancy, the GE IS200TSVCH1AJE delivers reliable performance in high-vibration turbine environments, supporting fuel control, steam admission, and speed governing applications.
