ABB AI810 3BSE008516R1 Analog Input Module

The ABB AI810 3BSE008516R1 is an 8‑channel single‑ended analog input module of the S800 I/O system, designed for ABB AC800M and 800xA DCS platforms. It acquires standard 4‑20mA and 0‑10V analog signals from field transmitters and converts analog measurements into digital data for the system controller.

This module adopts group isolation and built‑in PTC self‑reset overcurrent protection. It supports hot swapping and comprehensive channel diagnosis to guarantee reliable signal acquisition under harsh industrial interference. It is widely stocked as spare parts for DCS cabinet overhaul, system upgrade and on‑site replacement.
