ABB AO810 3BSE008522R1 S800 I/O Analog Output Module

Description

The ABB AO810 is an 8-channel analog output unit designed for the S800 I/O system to drive field devices such as control valve actuators, positioners, and variable speed drives. This module converts digital control signals from the AC 800M controller into precise 0-20 mA or 4-20 mA current signals. Engineered for reliability in industrial process control, the AO810 features integrated electrical isolation and robust monitoring capabilities to ensure accurate command execution and system stability across diverse automation environments.
