Why Choose the ABB AI531-XC Analog Input Module?

The ABB AI531-XC, part number 1SAP450600R0001, is an 8-channel analog input module designed for ABB AC500-XC and S500-XC automation systems. As an XC version for extreme environmental conditions, it provides flexible signal measurement for voltage, current, resistance, RTD and thermocouple applications in demanding industrial environments.

The AI531-XC provides 8 configurable analogue inputs with 16-bit resolution including sign. The inputs support a wide range of analogue and temperature signal types, including voltage, current, Pt100, Pt1000, Ni1000, Cu50, resistance and thermocouples, allowing one module to accommodate diverse field instrumentation requirements.

Designed for ABB AC500-XC systems, the AI531-XC can be used for central expansion of AC500-XC CPUs or for decentralised expansion when combined with a suitable communication interface module. The module is galvanically isolated at module level and uses a 24 V DC process supply, providing a flexible interface for industrial measurement and control applications.
