Product Overview

The AO810, cataloged as 3BSE008522R1, is a high-density analog output module within the ABB S800 I/O system, specifically engineered for precision control of field actuators. This module converts digital control commands into standardized 0...20 mA or 4...20 mA current signals, enabling the Distributed Control System (DCS) to govern various field devices with high granularity. Built for high-availability environments, the AO810 features integrated electrical isolation and a compact form factor that allows for seamless integration into 800xA or Advant OCS architectures. Its primary role is to ensure that setpoint instructions from the controller are translated into stable, noise-free analog signals for critical process modulation.
