ABB 3BSE008516R1 Analog Input Module

The ABB AI810 Analog Input Module (3BSE008516R1) is an 8-channel PLC input module for ABB S800 I/O and 800xA automation systems, converting field analog signals into digital data for PLC processing. It accepts multiple input types—0–20 mA, 4–20 mA, 0–10 V, and 2–10 V—with 12-bit resolution, single-ended inputs and a common return, and provides 250 ohms input resistance with PTC protection and short-circuit protection up to 30 V DC. Mounted on the S800 backplane (rack-mounted), it offers group isolation from ground and weighs approximately 0.19 kg. Applications include analog signal acquisition in PLC/DCS environments such as process control, manufacturing, energy plants, and chemical processing, with common replacements including ABB AI815, AI825, and AI843.
