Industrial Control I/O Interface Characteristics

The IS200EAUXH1AAA provides auxiliary discrete I/O expansion within GE Mark VI turbine control architectures. The terminal board interfaces field switches, sensors, trip relays, and auxiliary devices through isolated input channels and relay driver outputs.

The board follows GE industrial control platform requirements with I/O density scaling support, backplane bus communication compatibility, and firmware flash compatibility within supported Mark VI controller configurations. Signal conditioning functions including EMI filtering and surge suppression reduce interference effects on discrete control signals.

Optical/electrical isolation separates field circuits from controller-side electronics, supporting defined signal boundaries during turbine monitoring and protection operations.
