ABB AI03 is an RTD analog input module engineered for industrial temperature monitoring and process control systems. As part of the ABB Symphony Plus SD Series I/O platform, the module is designed to receive and process resistance temperature detector (RTD) input signals with high accuracy and operational stability.

The module supports 2-wire, 3-wire, and 4-wire RTD configurations, allowing flexible integration with various industrial temperature sensing applications. Each channel can be independently configured to support different RTD types, helping users optimize measurement performance for specific process requirements.

Featuring 16-bit analog-to-digital conversion, automatic calibration, signal isolation, and industrial-grade protection, the ABB AI03 provides reliable temperature acquisition even in electrically noisy environments. Its robust design makes it suitable for continuous operation in mission-critical industrial systems.
