ABB UNS0867 HIEE405246R0002 Excitation & I/O Extension Card
UNS0867 HIEE405246R0002 is marketed as both a high-performance excitation control board (UNS 0867A-P, V2) and a plug-in I/O extension card for ABB Advant OCS and AC 800M systems. All variants share the same physical board and are factory-flashed for the target application.
