ABB identifies TU531 for 120/230 V AC and relay I/O modules. Confirm the exact inserted module against the terminal-unit compatibility table.
TU531 uses screw terminals. Keep that termination method in the maintenance plan and verify conductor preparation requirements.
No. The plugged I/O module determines channel function and most terminal assignments; TU531 provides the compatible field termination and bus connection.
Verify the documented AC or relay application together with the internally commoned process-supply and zero-potential terminals for the selected module.
Do not assume a direct exchange. Screw and spring terminal units have different connection methods; confirm conductor routing, module compatibility and approved drawings.
Confirm rail seating, grounding, orientation, bus engagement, conductor torque or spring clamping, clearances and safe isolation before work.
Verify that the new module is approved for this terminal unit, then check every terminal assignment, supply group, diagnostic indication and controlled output response.
ABB ordering data lists approximately 0.238 kg per unit. Use the complete cabinet assembly data for rail and shipping calculations.
Provide TU531, 1SAP217200R0001, quantity, destination, inserted I/O model, voltage class, conductor type and clear photos of both labels.
