ABB 1SAP111100R0170 - TB511-ETH CPU Terminal Base

The ABB 1SAP111100R0170 is the order code for the TB511-ETH CPU terminal base, a one-slot module carrier with an Ethernet interface for the ABB AC500 PLC family. Distributor listings and product documentation identify it as a terminal base with 24 VDC supply and spring terminals, and ABB's product information notes that this code has been replaced by 1SAP111100R0270, the newer TB511-ETH revision with screw terminals. The terminal base is where the CPU and communication modules mount and wire to the field, so it is a common spare for AC500 installations. Refurbished and new surplus stock is offered by several specialists with warranty. Confirm terminal style and replacement code before ordering.
