Introduction
The IS200EROCH1ABB is an emergency relay output module manufactured by GE for Mark VI/VIe control architectures. It serves as a protective interface that converts system logic into hardwired relay outputs for shutdown, trip, or interlock functions. Its stable relay actuation and durable contact design make it a dependable component for turbine protection and high-integrity safety chains.
The board is especially valued in environments where command certainty and response time directly affect operational safety.
