ABB DA502-XC:S500, Digital Analog I/O Module

Why Choose the ABB DA502-XC Digital/Analogue I/O Module?

The ABB DA502-XC is a versatile digital and analogue input/output expansion module designed for ABB AC500-XC and S500-XC industrial automation systems. It combines high-density transistor outputs, configurable digital I/O and analogue signal processing within a single module, making it well suited to mixed-signal machine and process control applications.

The DA502-XC provides 16 digital transistor outputs at 24 V DC, eight configurable 24 V DC digital input/output channels, four analogue inputs and two analogue outputs. The digital outputs and configurable output channels support loads up to 0.5 A per channel, while the analogue section supports voltage, current and RTD measurement together with voltage and current output signals.

As the XC version of the DA502, the module is designed for operation under extreme ambient conditions while retaining the flexible mixed-I/O functionality of the standard model. Integrated fast counter functionality, module-wise galvanic isolation and modular S500-XC construction make it a practical solution for demanding industrial automation installations.

Flexible Mixed-Signal Output Control for Industrial Automation

The ABB DA502-XC combines a substantial number of digital actuator outputs with configurable digital channels and analogue signal interfaces. This allows solenoid valves, relays, contactors and other 24 V DC loads to be controlled alongside analogue transmitters, RTD sensors and analogue-controlled equipment without requiring separate modules for every signal type.

Its integrated fast counter adds high-speed signal processing using selected configurable digital channels, with dedicated counter operating modes capable of controlling either DC18 or DO0. Combined with the XC environmental design and modular S500 architecture, this makes the DA502-XC suitable for compact automation systems that require both flexible signal handling and dependable operation in demanding environments.
