ABB AC500 S500 DA502

Combined Digital and Analog Input/Output Module

DA502 combines digital outputs, configurable digital I/O and analog measurement and control channels in one AC500/S500 module. It is intended for compact applications that require mixed field signals without separate digital and analog modules.

Digital Resources The module provides 16 dedicated 24 V DC transistor outputs plus eight configurable 24 V DC digital I/O points. Each digital output is rated to a maximum of 0.5 A.	Analog Measurement and Control Four analog inputs support voltage, current and RTD signals with 12-bit-plus-sign resolution. Two analog outputs provide configurable voltage or current control signals.
Ranges and Performance Input ranges include 0 to 10 V, -10 to +10 V, 0 to 20 mA, 4 to 20 mA, Pt100, Pt1000 and Ni1000. Typical analog error is 0.5%, with a 1 ms analog conversion cycle.	Electrical and Load Data Supply is 24 V DC with maximum 5% ripple. Outputs O0 to O15 are limited to 4 A total, while configurable points DC16 to DC23 form a separate 4 A group.
Mechanical Integration DA502 installs on a TU515 or TU516 terminal unit using a 35 mm DIN rail. The assembled envelope is approximately 67.5 x 135 x 84.5 mm and module weight is about 125 g.	Protection and Selection The IP20 module operates from 0 to 60 °C horizontally or 0 to 40 °C vertically with derating. Confirm DA502 and order number 1SAP250800R0001 before procurement.

I/O Functions

Digital resources

DA502 provides 16 dedicated 24 V DC transistor outputs and 8 additional configurable 24 V DC digital I/O points.

Analog measurement

Four analog inputs accept voltage, current and RTD signals with 12-bit-plus-sign conversion.

Analog control

Two 12-bit-plus-sign analog outputs support voltage or current actuation, while the integrated fast counter operates to 50 kHz.

Electrical Data

Power system

The module uses 24 V DC process power with maximum 5% ripple and ABB specifies a 10 A fast external fuse.

Digital load groups

Outputs O0 to O15 are limited to 4 A total, and configurable points DC16 to DC23 form a separate 4 A group.

Analog performance

The four analog inputs and two outputs complete a conversion cycle in 1 ms; RTD measurement uses a 1 s cycle. Typical analog error is 0.5%.

Installation

Field termination

DA502 mounts on a TU515 or TU516 terminal unit, which carries the I/O bus and field wiring connections.

Rail installation

Install the assembled unit on a 35 mm DIN rail and keep the documented 20 mm spacing for ventilation and wiring.

Signal segregation

Route analog and digital wiring according to ABB EMC guidance; apply the specified shielding and grounding for low-level analog signals.

Environment

Control cabinet use

The IP20 module must operate inside a suitable enclosure that protects it from conductive contamination and direct contact.

Temperature limits

Horizontal operation is specified from 0 to 60 °C. Vertical installation is limited to 0 to 40 °C with output-group derating.

Storage range

ABB specifies -40 to 70 °C for storage and transport and up to 95% relative humidity without condensation.

FAQ

1. How can purchasing confirm the full DA502 identification?

Require label images showing DA502 and order number 1SAP250800R0001. Confirm the combination of 16 digital outputs, 8 configurable digital I/O, 4 analog inputs and 2 analog outputs.

2. How are new and refurbished DA502 modules distinguished?

Inspect dated photos of the terminal contacts, rail latch, analog connector area and housing. Wiring impressions, scratches, dust or component rework indicate previous service.

3. What makes a DA502 supplier verifiable?

Validate its registered company record, physical address, traceable quotation, beneficiary details and ability to show the exact DA502 label and serial evidence.

4. Which DA502 specifications must an engineer review?

Check 24 V DC supply, digital group current limits, required analog ranges, 12-bit-plus-sign conversion, RTD support, 50 kHz counter needs and TU515 or TU516 compatibility.

5. Which physical records should be obtained before payment?

Request current full-label photos, connector and terminal close-ups, packaging images and a video or functional evidence covering analog and digital channels when agreed.

6. Can DA501 or another DA-series part replace DA502?

A similar code is not automatically interchangeable. Digital channel allocation, analog ranges, counter resources and terminal mapping must be compared and approved by engineering.
