AI830A S800 I/O 8-Channel RTD Unit | ABB AI830A 3BSE040662R1

Product Description

The AI830A (Part Number: 3BSE040662R1) is a high-precision analog input module designed for the ABB S800 I/O system, specifically engineered for Resistance Temperature Detector (RTD) measurements. Unlike standard voltage/current modules, the AI830A provides direct interfacing for 3-wire RTD sensors, offering onboard linearization and high-resolution A/D conversion for accurate temperature monitoring in critical industrial processes.

This module features 8 differential input channels, each capable of supporting various RTD types such as Pt100, Cu10, and Ni120. The AI830A 3BSE040662R1 is designed for robustness, providing a rated isolation voltage of 50V and a compact form factor that integrates seamlessly into ABB AC 800M controllers via Module Termination Units (MTUs). Its high-speed processing and 14-bit resolution ensure deterministic data acquisition, making it a standard choice for thermal monitoring in power generation, oil and gas, and chemical processing facilities.
