GE 531X307LTBAJG1 LAN I/O Terminal Drive Board
Description：
531X307LTBAJG1 is part of GE 531X series LAN I/O terminal board. It is an I/Otermination board that serves as an interface between the control core and other devices. Ribbon cable RPL allows software variables pointed to the seven low voltage, low current, form C LTB output relays to control higher voltage, higher current, formC RTBA board relays. Jumper settings on the RTBA board determine if the LTB relays or externalconnections operate the RTBA relays. The eight LTB (or LUP) inputs are connected to the LDCC board via 8PL for use by the regulator controls.
