Overview

The ABB AI625 Analog Input Module is designed for high-accuracy signal acquisition in demanding industrial environments. With 16 analog input channels and 12-bit resolution, it delivers reliable performance for monitoring current-based sensors and transducers. The module is part of ABB’s S600 I/O family and integrates seamlessly with Advant Master and Symphony Plus control systems.

Moreover, the AI625 supports 0–20 mA input signals and features galvanic isolation for enhanced noise immunity. Its compact form factor and modular design simplify installation in control cabinets and distributed automation architectures. Therefore, it’s ideal for applications requiring precise analog data in power generation, chemical processing, and manufacturing.

In addition, the module’s robust construction and proven reliability make it suitable for continuous operation in harsh industrial conditions. Engineers benefit from its stable signal conversion and compatibility with ABB’s legacy and modern control platforms.
