531X305NTBAMG1is an NTB/3TB Terminal Board developed by General Electric for the EX2000 drive and exciter control systems. Installed inside the drive or exciter cabinet, this board serves as a passive interface for most external signal-level I/O connections. It houses terminal points and interface circuitry that allow communication between the drive control board, power supply board, and external field devices. The board connects to the drive control board through connectors 6PL and 8PL, to the power supply board via 2PL and 4PL, and to external equipment using COMPL and terminal board 3TB.
