IS200EROCH1A - EROC Exciter Regulator Options Board | GE EX2100 | B7B

IS200EROCH1A is a General Electric EROC Exciter Regulator Options Board for GE EX2100 excitation control systems. In the simplex EX2100 control rack, the EROC board provides ground detector oscillator output and sensing voltages, along with a serial interface for the Control System Toolbox and keypad connection.

The GEH-6632G EX2100 user guide describes the EROC as a single-slot, 6U card installed in the left-most slot of the simplex control rack, working with the EXAM, DSPX, and EBKP boards; the source describes this board in a simplex-only control-board overview. For maintenance, repair, and spare-part planning, IS200EROCH1A is an important replacement options board when supporting EX2100 excitation control cabinets, redundant or simplex control architectures, and turbine-generator excitation system reliability.
