GE 531X309SPCAJG1 Processor Board in stock

GE 531X309SPCAJG1 is a signal processor board for GE DC2000 drive and EX2000 excitation system. It handles encoder and tachometer speed feedback, current and voltage reference signal conditioning, and serves as the signal interface matched with SDCC main control card.

This legacy circuit board is discontinued. It is widely used as spare parts for heavy-duty DC drive and generator excitation cabinet overhaul, with potentiometers and DIP switches for gain adjustment and signal configuration.
