ABB 1KGT033000R0001 - 520ADD01 R0001 I/O Adapter Board

The ABB 1KGT033000R0001 is the order code for the 520ADD01 I/O adapter (R0001) in the ABB RTU520 product line, described in ABB's own product records as a standard adapter board for up to 8 I/O modules such as the 520BID01 digital input module. The adapter is the backplane card that hosts and addresses RTU520 I/O modules, so it is a structural spare for remote terminal assemblies in utility and industrial substations. Distributor listings pair the code with the 520ADD01 designation and offer units in stock. Confirm your RTU520 rack layout and the I/O module types you need to host before ordering.
