TU532 S500 120/230 V AC Relay Spring-Terminal I/O Unit

Structured mounting and field termination for documented ABB automation assemblies.

Product Summary

ABB TU532 is an S500 I/O terminal unit for AC500 modules using 115 to 230 V AC inputs or 120/230 V AC relay outputs. Its spring-terminal design supports front-access conductor connection across forty signal and process-supply terminals. The terminal unit carries the station I/O bus between adjacent devices and secures the inserted I/O module with mechanical locks, allowing module service without removing the fixed field wiring. TU532 is appropriate for modular control cabinets, relay I/O expansion and replacement projects where spring terminals are specified. Confirm the complete code, module type, field voltage, terminal assignment and mounting details before purchase.

Installation and Verification Route

Confirm the standard version

Check that the requirement is TU532 rather than an -H or -XC variant.

Mount and ground the assembly

Install on the documented DIN rail or screw-mounting arrangement.

Wire the spring terminals

Connect conductors according to the inserted module terminal plan.

Lock and inspect the module

Seat both mechanical locks and verify voltage separation before energizing.

Typical Applications

Spring-terminal connection for S500 AC input modules
Relay-output wiring in AC500 control panels
Modular I/O expansion using front-access terminals
Replacement of an installed TU532 terminal unit

Compatibility and Revision Notice

Confirm TU532 and order code 1SAP217000R0001. Do not mix the standard TU532 with TU532-H, TU532-XC or TU532-H-XC. Verify the inserted I/O module, field voltage, spring-terminal conductor preparation, channel allocation and label photographs.

Procurement FAQ

What terminal technology is used by TU532?

TU532 uses spring terminals for front-access conductor connection.

What module voltage range is associated with TU532?
