Product Overview

TU532 is an ABB AC500/S500 I/O terminal unit identified by order number 1SAP 217 000 R0001.

It provides 40 spring terminals, the I/O bus interfaces and the mechanical connection for compatible ABB modules with 115 V AC to 230 V AC inputs and/or 120/230 V AC relay outputs.

The plug-in I/O module is retained by two mechanical locks, so field wiring remains on the terminal unit when a compatible module is removed after the system is safely de-energized.

Applications & Features

Spring-terminal wiring

Forty front-access spring terminals provide field connections for signals and process supply voltage.

Modular I/O interface

Male and female 10-pin I/O bus connectors link the terminal unit to the adjacent terminal base, communication interface or terminal units.

Wiring retention

A compatible I/O module plugs into the terminal unit, allowing field wiring to remain on the base during controlled module replacement.

AC and relay application

The terminal unit is specifically designed for compatible modules with 115 V AC to 230 V AC inputs and/or 120/230 V AC relay outputs.

Connections

Terminals 1.8 to 4.8	Internally interconnected process supply UP terminals; maximum 30 V DC within the published terminal-unit limit.
Terminals 1.9 to 4.9	Internally interconnected process supply ZP terminals; maximum 30 V DC within the published terminal-unit limit.
Signal terminal groups	Four groups of eight channels: 1.0 to 1.7, 2.0 to 2.7, 3.0 to 3.7 and 4.0 to 4.7.
I/O bus	The module circuitry receives 24 V DC through the I/O expansion bus; actual signal assignment depends on the inserted compatible I/O module.
Grounding	Directly through the grounded DIN rail or through the mounting screws when wall mounted.

Installation

01 - Verify compatibility

Confirm TU532, order number 1SAP 217 000 R0001, the inserted module type, voltage class, connector layout and terminal assignment.

02 - Mount the terminal unit

Snap onto a 35 mm top-hat DIN rail or use the specified ABB wall-mounting accessories with M4 screws tightened to a maximum of 1.2 Nm.

03 - Lock the I/O bus

Slide the terminal unit fully into the adjacent unit or terminal base so the I/O bus connectors are securely engaged.

04 - Wire spring terminals

Use the terminal assignment and conductor requirements of the inserted I/O module. Do not exceed the published voltage and current limits.

05 - Commission safely

De-energize the applicable circuits, verify grounding and wiring, then test the installed module according to its ABB instructions.

Environment

Standard temperature

Horizontal mounting: 0 to +60 degrees C. Vertical mounting: 0 to +40 degrees C with output load reduced to 50 percent per group.

Storage and transport

-40 to +70 degrees C.

Humidity and altitude

Maximum 95 percent non-condensing; operating altitude below 2000 m with air pressure above 800 hPa.

Vibration

2 to 8.4 Hz at 3.5 mm peak and 8.4 to 150 Hz at 1 g, all three axes.

Shock

15 g, 11 ms, half-sine, all three axes.

System standard

Industrial control equipment; IEC 61131-2, zone B; PLC system protection rating IP20 when correctly assembled.

FAQ

Q1. How can a buyer verify the exact quoted TU532?

Match model TU532 and order number 1SAP 217 000 R0001 on the quotation, product label and packaging. Confirm 40 spring terminals and the standard non-XC, non-hot-swap version.

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

Request current photos of the ABB label, spring terminals, male and female I/O bus connectors, module plugs, mechanical locks and DIN-rail latch. Check for terminal marks, bent contacts, discoloration, repaired plastic or changed labels.

Q3. How should supplier legality and reliability be checked?

Verify the supplier legal entity, registered address, payment beneficiary and traceable sales contact. The written offer should state ABB, TU532, order number 1SAP 217 000 R0001, New condition and quantity.

Q4. Which specifications must engineering confirm before purchase?

Confirm AC500/S500 generation, inserted I/O module compatibility, 120/230 V AC or relay application, spring-terminal requirement, 67.5 x 135 x 28 mm space, DIN-rail or screw mounting and environmental limits.

Q5. What physical evidence should be requested before payment?

Ask for date-marked photos showing the complete ABB label, order number, all 40 spring terminals, I/O bus connectors, module plugs, locks, DIN-rail latch and sealed packaging.

Q6. Can TU531, TU532-H or TU532-XC replace TU532?

Not automatically. TU531 uses screw terminals, TU532-H adds hot-swap capability and TU532-XC is the extreme-condition version. Match the exact order number, terminal type, environmental requirement and inserted module compatibility.
