ABB da501-xc:s500, digital analog input/output module

Why Choose the ABB DA501-XC Digital/Analogue I/O Module?

The ABB DA501-XC is a versatile digital and analogue input/output expansion module designed for ABB AC500-XC and S500-XC industrial automation systems. It combines digital inputs, configurable digital I/O, analogue inputs and analogue outputs within a single compact module, reducing the number of separate I/O modules required in mixed-signal automation applications.

The DA501-XC provides 16 digital inputs at 24 V DC, eight configurable 24 V DC digital input/output channels rated up to 0.5 A when used as outputs, four analogue inputs and two analogue outputs. Its analogue inputs support voltage, current and RTD measurement, while the analogue outputs provide voltage and current signals with 12-bit resolution including sign.

As the XC version of the DA501, the module is intended for operation under extreme ambient conditions while retaining the flexible mixed-I/O functionality of the standard model. An integrated fast counter, module-wise galvanic isolation, diagnostic LEDs and compatibility with ABB S500 terminal units make the DA501-XC suitable for demanding machine, process and infrastructure automation.

Flexible Mixed-Signal I/O for Industrial Automation

The ABB DA501-XC allows digital sensors, switching devices, analogue transmitters, resistance temperature detectors and analogue-controlled equipment to be connected through a single S500-XC expansion module. Combining multiple signal types within one module can simplify control cabinet layouts and provide a flexible I/O configuration for machinery and process automation systems.

The integrated fast counter extends the module beyond conventional I/O by supporting high-speed counting functions through selected configurable digital channels. Module-wise galvanic isolation, comprehensive channel protection and the XC environmental design make the DA501-XC particularly suitable for distributed and centralised control systems operating under demanding industrial conditions.
