AI830A | ABB AI830 Analog Input RTD

Overview

The AI830/AI830A RTD Input Module is a versatile and reliable analog input module from ABB’s S800 I/O series, designed to measure temperature using resistive elements (RTDs) like Pt100, Cu10, Ni100, Ni120, and resistive sensors. It offers linearization and conversion to Centigrade or Fahrenheit directly on the module, ensuring accurate temperature readings. The module supports 3-wire RTD connections and ensures isolation from ground for reliable operation in various industrial environments.
