Product Overview

The ABB TU515 (Order Code: 1SAP212200R0001) serves as a fundamental mounting and wiring foundation for the S500 I/O expansion modules within the AC500 PLC ecosystem. This terminal unit is engineered to simplify field wiring by providing a secure interface for I/O modules to connect with the bus and power supply. By separating the electronic I/O module from the physical wiring base, the TU515 allows for "permanent wiring," enabling modules to be swapped or upgraded without disturbing the field connections. This architecture significantly reduces the risk of wiring errors and minimizes maintenance-related downtime in sophisticated distributed control systems.
