More Information

Overview Manuals Specifications Relay Module Fit Screw Wiring AC Review

Features:

  • Relay I/O base: Designed for supported AC500 relay-output module arrangements.
  • AC voltage class: The application is documented for 120/230 V AC circuits.
  • Screw connection: TU531 provides screw field terminals.

TU531 forms the terminal base for supported ABB AC500 relay I/O modules used with 120/230 V AC field circuits.

Circuit review should cover isolation, protective devices, terminal mapping, load type, inrush, suppression, conductor separation, and safe service access.

Procurement should verify 1SAP217200R0001 and the installed relay module because TU531 and TU532 differ in field-connection method.

Availability is subject to Apter Power's current inventory and sourcing confirmation.

Supported module review

  • Application group: Use TU531 for the relay I/O module group documented by ABB.
  • Module identity: Record the exact plug-in module order code before removal.
  • Voltage class: Confirm the field circuit is the documented 120/230 V AC application.
  • Terminal choice: Select TU531 only when screw field terminals are required.

AC conductor review

  • Connection type: TU531 uses screw terminals for field conductors.
  • Circuit map: Preserve line, return, protective devices, loads, and terminal numbers.
  • Load review: Record load current, inrush, duty, and suppression.
  • Inspection: Apply approved tightening and conductor-retention checks.

Safety and commissioning

  • Isolation: Use the site-approved mains isolation and verification procedure.
  • Protection: Confirm fusing and external protective devices against the circuit drawing.
  • Separation: Maintain required segregation between AC circuits and other wiring.
  • Functional test: Test each relay channel and interlock before automatic operation.
Description

What is ABB TU531 used for?
It provides screw-terminal field wiring for supported AC500 relay I/O modules in 120/230 V AC applications. Confirm the module and circuit first.
Which family includes TU531?
TU531 belongs to ABB AC500 S500 terminal units. It is specifically documented for the relay I/O terminal-unit group.
How do I verify TU531 before ordering?
Match TU531 and 1SAP217200R0001 on the label and official ordering data, then verify the plug-in relay module and AC circuit.
How does TU531 differ from TU532?
Both serve the documented relay I/O application, but TU531 uses screw terminals and TU532 uses spring terminals.
Is TU531 active or discontinued?
ABB identifies TU531 as Active in the reviewed datasheet. Availability remains subject to Apter Power sourcing confirmation.
Is an official TU531 replacement listed?
The reviewed ABB datasheet does not identify a replacement. Do not change the terminal unit without module and wiring validation.
Where can I request TU531 documents, price, and lead time?
Use the verified PDF in Manuals and provide Apter Power the plug-in module, quantity, condition, destination, and required date.
