- Description
The ABB 1SAP211200R0001 (TU518) is a spring-terminal interface unit for the AC500 S500 communication interface modules, built with a bus connection made through spring terminals rather than a fixed connector. It sits between the communication module and the field network cabling, so the module can be unplugged for service without disturbing the bus wiring. Spring-clamp terminals secure the bus conductors without a screwdriver, and ABB rates the base IP20.

Selection Notes
TU518 terminates its serial bus connection through spring terminals, so bus conductors push in and release with a flat-blade tool rather than a screw turned and torqued per pole. It carries the same bus-connection layout as the screw-terminal version of this base, so the decision between the two comes down to the panel builder's termination standard rather than electrical capability. Use it only with a communication interface module built for this terminal-style bus connection.
