The ABB AO810 (Part No. 3BSE008522R1) is an 8-channel analog output (AO) module designed for the ABB S800 I/O system and System 800xA / AC 800M controllers. It converts digital control signals from the controller into precise analog signals for controlling field devices such as control valves, variable frequency drives (VFDs), actuators, and process instruments.

Key Features

• 8 independent analog output channels
• Supports 0–20 mA and 4–20 mA current outputs
• High-resolution digital-to-analog conversion for accurate process control
• Built-in self-diagnostics and open-circuit detection
• Continuous monitoring of D/A converter communication
• Short-circuit protected outputs
• Suitable for single and redundant controller configurations
• Seamless integration with ABB S800 I/O architecture

Typical Specifications
