GE IS200TRLYH2EAA Speedtronic Mark VI Relay Termination Board

The GE IS200TRLYH2EAA is a relay termination output board designed for GE Speedtronic Mark VI turbine control systems. It acts as signal interface between main control boards and field equipment, converting internal logic signals into relay contact outputs to control external valves, solenoids and auxiliary machinery.

This printed circuit board integrates multiple relay channels, signal filtering and surge suppression circuits to enhance anti-interference capability in harsh industrial environments. It is widely used for gas and steam turbine control cabinet maintenance, equipment upgrade and spare parts stocking in power and petrochemical industries.
