ABB AI810 (3BSE008516R1) Analog Input Module Overview
Brand Background
ABB is a global technology leader in electrification, industrial automation, robotics, and motion solutions. Within process automation, ABB supplies the S800 I/O platform—a modular, high-density distributed I/O system used extensively with ABB System 800xA, Compact Product Suite, and Freelance DCS. ABB’s process automation components are engineered to deliver maximum operational availability, superior signal integrity, and long-term durability across complex processing environments.
Model Overview: AI810 (Part Number: 3BSE008516R1)
The ABB AI810 (Part Number: 3BSE008516R1) is an 8-channel Analog Input Module belonging to the ABB S800 I/O system family.
Designed for reliable, single-ended analog signal acquisition, the AI810 module accepts standard unipolar current and voltage signals (0/4–20 mA or 0/2–10 V) from field transmitters and sensors. It converts analog process readings into digital values and transmits them across the ModuleBus backplane to central controllers such as the AC 800M.
