ABB DA502 S500 Digital/Analog I/O Module

A multifunction I/O module combining digital actuation, configurable digital channels, analog measurement and analog output functions in one S500 station position.

Product Summary

ABB DA502 is an S500 digital/analog I/O module for AC500 automation architectures. It combines 16 digital outputs, eight configurable digital input/output channels, four analog inputs and two analog outputs. The analog inputs support voltage, current and resistance temperature detector signals, while the analog outputs support voltage and current. An integrated fast counter and module-wise galvanic isolation support compact mixed-signal control designs. DA502 is suitable for planned maintenance, installed-base replacement and new I/O station configuration. Before ordering, compare the DA502 designation, ordering number, terminal unit, process supply, I/O-bus master support and terminal assignment with the installed assembly.

Key Product Information

Signal and Integration Workflow

Typical Applications

• Mixed digital actuation and analog measurement within an AC500 S500 I/O station.
• Compact machine-control panels requiring configurable 24 V DC digital channels.
• Temperature acquisition using supported resistance temperature detector inputs.
• Voltage and current signal acquisition and analog command output.
• Installed-base maintenance and like-for-like DA502 replacement planning.

Compatibility and Revision Notice

Before installation, compare the complete DA502 designation and ABB ordering number with the original product label. Confirm the terminal unit, I/O-bus master support, process supply, signal ranges, channel configuration and terminal assignments in the project documentation.

Do not substitute DA502-XC or another S500 module solely on a similar appearance or channel count. Review product and label photographs when replacing an installed module.
