The GE IS200SRLYH2AAA (also referenced as IS200SRLYH2A or IS230SNRLH2A) is a simplex relay output terminal board designed for GE Mark VI Speedtronic turbine control systems. It provides 12 isolated Form-C (SPDT) relay outputs for interfacing with external devices such as alarms, solenoids, contactors, and auxiliary control equipment.
This module is engineered for high reliability in industrial and power generation environments. It features electrical isolation between control logic and field wiring, compact modular design, and diagnostic LED indicators for real-time status monitoring.
