The ABB AI03 is a high-precision analog input module designed for ABB Symphony Plus SD Series I/O systems. The ABB AI03 is specifically engineered to process RTD (Resistance Temperature Detector) signals, making it ideal for temperature measurement applications in industrial automation.

The ABB AI03 provides reliable data acquisition, high accuracy, and strong noise immunity, ensuring stable operation in harsh industrial environments such as power plants, oil & gas facilities, and manufacturing systems.

In a power plant control system, the ABB AI03 is used to monitor critical temperature points:

Receives RTD signals from temperature sensors (e.g., turbine, boiler)

Converts analog signals into digital values

Sends real-time data to the control system (DCS)

With the ABB AI03, operators can continuously monitor temperature conditions and ensure safe, efficient operation of equipment.
