• PN: TU515, Part No: 1SAP212200R0001
• Brand: ABB
• Series: S800 I/O System, System 800xA DCS
• Type: Screw Terminal Unit

• Function: TU515 is a standard screw wiring terminal base matched with S800 series analog and 24VDC digital I/O modules. It realizes reliable electrical connection between field sensors, actuators and I/O modules, undertakes signal distribution, power transmission and wiring management tasks. Adopting screw terminal design, it ensures stable wiring for long-term industrial operation, and supports hot swapping of upper I/O modules without system shutdown, greatly facilitating on-site equipment maintenance and module replacement.
