ABB AI830 Overview

The ABB AI830 is an analog input module within the ABB Advant S800 (also known as 800xA) distributed control system. It is primarily used to convert analog signals from field instruments—such as voltage, current, or resistive temperature sensors—into digital signals that can be processed by the controller.

Dimensions / Weight: approx. 119 mm × 102 mm × 45 mm; weight ≈ 0.22 kg

Typical Applications

Temperature monitoring in industrial process control (chemical, oil & gas, power generation, etc.)

Machine monitoring and process data acquisition

Laboratory and research applications requiring high-precision analog or temperature measurement

Compatible Platforms

The AI830 module can be mounted on ABB terminal units such as TU810, TU812, TU814, and TU830, and supports PROFIBUS DP, Modbus RTU, and other fieldbus communication protocols.

Summary

In short, the ABB AI830 provides 8 high-precision, isolated analog input channels for reliable temperature and analog signal acquisition in industrial automation systems. It is one of the most commonly used temperature and analog input modules in the ABB Advant S800 series.
