ABB AI830 (AI830A, order code 3BSE040662R1) is a temperature measurement analog input module in the S800 I/O family, designed for ABB System 800xA and Freelance distributed control systems. This module provides 8 independent channels for 3-wire RTD temperature sensors, supporting Pt100, Cu10, Ni100, Ni120 and passive resistance signals.
The module performs linearization and temperature conversion internally, outputting temperature readings in Celsius or Fahrenheit directly. Each channel can be configured separately. Built-in channel diagnostics detect open-loop, short-circuit and sensor earth fault conditions and send alarm signals to the DCS controller. The module supports 50Hz /60Hz mains frequency noise filtering to suppress industrial interference.
AI830 requires matching S800 termination units for wiring connection. It can be hot-swapped within the S800 I/O rack, minimizing system downtime during maintenance. It adopts group isolation design to improve anti-interference performance in heavy industrial environments.
