Overview

The ABB AO810 is a high‑performance analog output module designed for ABB AC 800M controllers and the S800 I/O system. It provides 8 unipolar analog output channels, each capable of delivering current or voltage signals to field devices. The module continuously supervises communication with its D/A converters, performs cyclic self‑diagnostics, and reports channel errors if discrepancies are detected.

This makes the AO810 particularly valuable in process industries, power generation, and manufacturing automation, where precise analog control is critical for efficiency and safety.

Technical Data

Key Features

• 8 configurable analog outputs for current or voltage signals.

• High accuracy (12‑bit resolution) for precise control.

• Built-in diagnostics including open‑circuit and short‑circuit detection.

• Self-diagnostic cycles to ensure reliable operation.

• Hot-swap capability for reduced downtime during maintenance.

• Compact design for easy integration into ABB S800 I/O racks.

Typical Applications

• Process industries: Driving control valves, dosing pumps, and actuators.

• Power generation: Regulating turbine and boiler systems.

• Water treatment: Controlling mixers, pumps, and flow regulators.

• Manufacturing automation: Providing analog signals to drives and proportional controllers.

• Energy management: Interfacing with frequency converters and monitoring systems.

Example: In a chemical plant, the AO810 may convert a digital command from the AC 800M controller into a 4–20 mA signal that precisely adjusts a valve’s opening to regulate fluid flow.
