GE 531X307LTBAFG1 LAN I/O Terminal Board in stock

GE 531X307LTBAFG1 is a LAN I/O terminal board for GE EX2000 generator excitation system. It acts as the signal interface between the excitation main controller and field peripheral devices, collecting digital interlock signals and outputting relay control signals.

This legacy circuit board has been discontinued. It is widely used as spare parts for power plant excitation cabinet maintenance and renovation, supporting 8 configurable control inputs and 7 relay output channels for interlock and indicator control.
