2. Compatibility & Expandability

Same-brand Compatibility

ABB TU515 is dedicated terminal base matched with ABB AC500 modular I/O hardware. Electrical installers arrange multiple ABB TU515 on cabinet DIN rails to gather discrete field wiring for packaging and logistics automation racks. ABB TU515 locks beneath AC500 digital and analog I/O modules and conducts signal transmission with ABB PM5 series CPU without extra intermediate terminal strips. Buckle-type mechanical fixation maintains stable signal contact when ABB TU515 operates alongside all original ABB pushbutton stations and contactor actuators.

Cross-brand Compatibility

Exclusive AC500 module bottom buckle structure stops direct assembly of ABB TU515 onto third-party PLC hardware. Separate signal transfer terminal adapters are required to build wiring links connecting ABB TU515 to Siemens and Schneider I/O modules. General screw wiring specifications allow ABB TU515 to connect standard 24V third-party proximity sensors with no structural refitting on ABB TU515.
