The ABB AI830 (3BSE008518R1) functions as a high-precision analog input interface for the S800 I/O system. This module specifically targets temperature measurement using Resistance Temperature Detectors (RTDs). It converts resistance variations from field sensors into digital values for the controller. Consequently, the unit provides critical data for thermal process regulation and machinery protection.
Furthermore, the hardware handles eight independent channels for comprehensive site monitoring. Each channel supports various RTD types to ensure broad industrial compatibility. The module manages signal linearization and wire resistance compensation automatically to maintain data integrity.
