GE IS200TRLYH2EAA Relay Terminal Board

GE IS200TRLYH2EAA is a relay terminal board designed for GE Mark VI gas and steam turbine control systems. It serves as an interface board for relay signal routing, responsible for distributing trip, alarm and interlock signals inside the turbine control cabinet.

This PCB adopts industrial-grade circuit design with multiple terminal connectors for signal wiring and board-to-board connection. It transmits discrete contact signals between main control modules and field equipment. It is widely supplied as replacement spare part for power plant turbine control cabinet maintenance projects.
