Description
The ABB AI830 (3BSE008518R1) is an S800 I/O series analog input module designed for high-precision temperature and resistive signal measurement. This module provides eight channels specifically configured for 3-wire RTD inputs, supporting a variety of industry-standard sensors including Pt100, Cu10, Ni100, and Ni120, as well as resistive potentiometer inputs. As a component of the Advant S800 I/O system, it is engineered for distributed control environments where reliable signal processing is required.
Features
- Eight isolated analog input channels.
- Supports 3-wire RTD sensor types: Pt100, Cu10, Ni100, and Ni120.
- Integrated support for resistive potentiometer signal inputs.
- Efficient power dissipation of 1.6 W.
- High common-mode rejection ratio (CMRR) of >60 dB at 50/60 Hz to minimize signal noise.
- Compact design optimized for S800 I/O rack mounting.
