Description

The ABB AI830 (3BSE008518R1) is an 8-channel analog input module designed for the S800 I/O system. This module is specifically engineered for high-precision temperature measurement and resistance sensing, supporting a variety of RTD types and resistive potentiometers. As a key component of the Advant S800 I/O family, it provides reliable signal acquisition for industrial control applications.

Features

• 8 isolated input channels for RTD and resistance measurements.
• Supports multiple sensor types including Pt100, Cu10, Ni100, and Ni120.
• Integrated support for resistive potentiometer inputs.
• Optimized update cycle time of 150 ms + 9 ms.
• High common-mode rejection ratio (CMRR) of >60 dB at 50/60 Hz.
• Low power dissipation of 1.6 W for efficient cabinet thermal management.

Technical Specifications

Installation Guidelines

• Ensure the S800 I/O station is powered down before inserting or removing the module from the mounting base.
• Handle the module using ESD-safe practices to prevent damage to sensitive internal circuitry.
• Verify that the module is correctly seated in the terminal unit to ensure proper connection to the Modulebus.
• Route signal cables away from high-voltage power lines and sources of electromagnetic interference (EMI) to maintain signal integrity.
• Maintain adequate ventilation within the control cabinet to stay within operating temperature limits.
