ABB S500 TU531 Relay Terminal Unit

Exact configured model: TU531

Official product identity

TU531 is the ABB S500 terminal unit for 120/230 V AC relay applications. The exact article uses screw terminals and order number 1SAP217200R0001.

Configured geometry

The official dimensional drawing specifies approximately 67.5 mm width, 135 mm height and 76 mm depth. Typical weight is 200 g.

Connection package

Thirty-two channels are arranged in four groups of eight. Main channel terminals support up to 300 V AC and 3 A, subject to the inserted I/O module and internal connector limits.

Installation focus

Mount the TU531 horizontally or vertically, ground it through the DIN rail or wall-mounting screws, use the correct screw-terminal wiring, and observe all hazardous-voltage separation rules.

Procurement check

Match every segment of TU531. Confirm TU531 and 1SAP217200R0001. TU532 uses spring terminals, while TU532-H and TU532-XC are different hot-swap or XC products.

Construction

Relay-terminal architecture

The terminal unit provides 32 positions arranged in four groups of eight for the inserted relay I/O module.

Screw-terminal wiring

Front screw terminals accept conductors vertically to the printed circuit board.

Voltage segregation

Auxiliary terminals are limited to 30 V DC, while main channel terminals are rated up to 300 V AC under the applicable module limits.

Grounding path

The assembly grounds through the DIN rail or the wall-mounting screws.

Installation

Hazardous-voltage safety

Use safe separation and approved wiring practices for 120/230 V AC relay circuits.

DIN-rail mounting

Install on the specified 7.5 mm or 15 mm depth DIN rail or use the approved screw-mounting arrangement.

Current limits

Observe the 10 A auxiliary total-current limit and the 3 A main-channel terminal limit.

Enclosure

The IP20 assembly must be installed inside a suitable enclosure with all terminals and covers fitted.

Selection Guide

TU531

120/230 V AC relay terminal unit with screw terminals.

Order number

1SAP217200R0001.

Channel capacity

32 channels in four groups of eight.

Main terminals

Up to 300 V AC and 3 A within inserted-module limits.

TU532 difference

TU532 uses spring terminals.

TU532-XC difference

TU532-XC is the separate XC version.

TU532-H difference

TU532-H is the separate hot-swap version.

Environment

Operating temperature

0 to +60 °C horizontally; 0 to +40 °C vertically with output load limited to 50% per group.

Storage and transport

-40 to +70 °C.

Humidity and altitude

Maximum 95% noncondensing; observe the official altitude and air-pressure limits.

Protection and safety

IP20 for the completely assembled PLC system; use a protective enclosure for live AC relay wiring.

FAQ

Q1. How do I verify that the quotation is for the exact terminal unit?

Require TU531 and order number 1SAP217200R0001 on the label, quotation and packing evidence. Confirm 120/230 V AC relay use and screw terminals.

Q2. How can New, Used and Refurbished condition be distinguished?

Request current close-up photographs of the label, screw-terminal blocks, module connectors, DIN-rail latch and housing. Check for conductor marks, stripped screws, heat discoloration, cracks or altered labels.

Q3. How can the supplier be checked for legitimacy and reliability?

Verify the legal company name, registration, address, bank beneficiary and traceable contacts. Compare the exact article with ABB Data Sheet 3ADR010074 Rev. 15.

Q4. Which specifications must an engineer confirm before purchase?

Confirm relay-module compatibility, screw terminals, 32-channel grouping, 300 V AC and 3 A channel limits, 30 V DC auxiliary limit, 10 A auxiliary total current and mounting dimensions.

Q5. What physical evidence should be requested before payment?

Ask for dated photographs or video showing TU531, 1SAP217200R0001, every screw terminal, internal connectors, DIN-rail feature and the undamaged housing.

Q6. Can TU532, TU532-XC or TU532-H replace it?

Not automatically. TU532 changes to spring terminals, TU532-XC changes the environmental version and TU532-H adds hot-swap construction. Verify wiring and system approval before substitution.
