Products Description
GE IS200TRPGH1BDE Terminal Relay Board in stock
GE IS200TRPGH1BDE is a conformal coated TRPG trip return terminal board for GE Speedtronic Mark VI and Mark VIe turbine safety systems. It provides the negative 125VDC return path for emergency trip solenoid circuits, normally matched with IS200TREGH1BEC positive trip board to form complete energize-to-trip safety loops for independent overspeed protection.
This board integrates 8 isolation relays and MOV surge suppression, supports 2oo3 TMR voting logic together with VPRO overspeed processor packs. The conformal coating protects PCB against moisture and corrosion, widely used as spare parts for gas and steam turbine ESD protection cabinets in power plants.
