ABB AI630 3BHT300006R1 Analog Input Module

The ABB AI630 (part number 3BHT300006R1) is a 12-channel analog input module designed for precision temperature measurement in AC 800M, System 800xA, and Symphony Plus control architectures. It is optimized for interfacing with Pt100 Resistance Temperature Detectors (RTDs), incorporating channel-to-channel galvanic isolation to maintain high signal accuracy and noise immunity in severe electrical environments.

Technical Specification

Temperature Signal Acquisition and Isolation

The AI630 provides high-resolution analog-to-digital conversion across 12 dedicated channels configured for standard Pt100 sensors. Integrated galvanic isolation separates the sensitive input processing electronics from field-side ground loops and common-mode noise, suppressing interference when monitoring critical process temperatures across wide physical distances.

System Integration and Control Architecture

Designed to interface directly with ABB AC 800M controllers, the module transmits digitized thermal data across the system bus to System 800xA or Symphony Plus control platforms. Its standardized mounting footprint enables straightforward insertion into DCS I/O racks, facilitating structured cabinet wiring and routine maintenance routines.
