ABB AO810

Product introduction

The AO810 is a high-performance analog output module from ABB, designed for the S800 I/O system to convert digital control signals from the AC800M controller into precise analog outputs for industrial actuators and devices. As a key component in closed-loop control systems, it enables accurate regulation of processes by sending proportional signals to valves, variable speed drives, and other final control elements.

With 4 isolated channels supporting multiple signal types, the AO810 offers flexibility for diverse applications, from simple voltage-controlled devices to current-loop actuators. Its 16-bit resolution and ±0.1% accuracy ensure that even small adjustments in the control signal translate to precise changes in process variables, critical for maintaining product quality in industries like pharmaceuticals and semiconductor manufacturing. Whether integrated with AI815 analog input modules for feedback control or paired with CI840A for networked operation, the AO810 delivers reliable performance, making it a staple in modern industrial automation.

Core advantages and technical highlights

Precise output control

AO810’s 16-bit resolution and tight accuracy specifications ensure consistent signal delivery, even over long cable runs. In a water treatment plant, this precision allows the module to regulate a chemical dosing valve with 0.1% flow accuracy, ensuring optimal water treatment without chemical waste. When paired with an AI815 module monitoring pH levels, the closed-loop system maintains water quality within strict regulatory limits.

Channel isolation

Each channel of the AO810 features 2.5 kV AC isolation, preventing cross-talk between signals and protecting the controller from voltage spikes in the field. In a factory with multiple drives and motors, this isolation ensures that a voltage surge on one channel (e.g., from a faulty valve) won’t affect the other three channels, maintaining control of critical processes like temperature regulation in an adjacent reactor.

Robust protection features

Integrated short circuit and overcurrent protection safeguards both the AO810 and connected devices. If a valve actuator develops a short circuit, the module limits current to a safe level and triggers an alert, allowing maintenance to address the issue without damaging the module or controller. This feature is particularly valuable in hazardous environments where replacing components is costly and time-consuming.

Typical application scenarios

In a food and beverage bottling plant, the AO810 plays a central role in regulating filling processes:

• Channel 1: 4-20 mA signal to control the main filling valve, adjusting flow rate based on bottle size data from the AC800M controller.
• Channel 2: 0-10 V output to a level sensor calibrator, ensuring accurate fill height across different bottle types.
• Channels 3-4: ±10 V signals to servo drives controlling conveyor speed, synchronizing with filling rates to prevent spills.

The AO810 works alongside AI815 modules monitoring fill weights, creating a closed-loop system that maintains fill accuracy within ±0.5%—critical for meeting labeling regulations and reducing product waste.

In a plastics extrusion facility, the AO810 controls temperature and pressure in the extrusion process:

• Sends 4-20 mA signals to heater controllers, maintaining barrel temperatures within ±1°C.
• Regulates a pressure valve on the extruder die, adjusting to material viscosity changes detected by upstream sensors.

Its ability to handle both current and voltage signals allows the module to integrate seamlessly with different types of actuators, simplifying system design and reducing component inventory.

Installation, commissioning and maintenance instructions

Installation preparation

Before installing AO810, ensure the S800 I/O rack is powered off. Mount the TB820V2 terminal base on a 35 mm DIN rail, leaving 20 mm clearance between modules for airflow. Use shielded twisted-pair cables (0.5-1.5 mm²) for field connections, routing them separately from power cables to minimize noise. Connect each actuator to the appropriate channel terminals, verifying polarity for current loops. Power the module via the S800 backplane, ensuring the 24 V DC supply is stable and within ±10% tolerance.

Maintenance suggestions

Daily checks of AO810 involve verifying green LEDs for power and active channels; red LEDs indicate faults requiring attention. Calibrate the module annually using a precision signal generator to maintain accuracy, especially in regulated industries. Inspect terminal connections quarterly for tightness and corrosion, tightening screws to 0.6 Nm if needed. If a channel fails, swap the load to a spare channel to isolate the issue—replace the AO810 with an ABB-approved spare if the fault persists, ensuring the replacement is configured with the same signal ranges as the original.
