Product Introduction
A control system can calculate the correct output command and still fail to position a valve or regulate a drive if the analog signal reaching the field device is incorrect. The ABB AO810V2 addresses this interface requirement through eight unipolar current-output channels for 0–20 mA and 4–20 mA applications within the S800 I/O platform.
With 14-bit resolution, cyclic diagnostics, and output readback verification, the module supports controlled signal delivery and fault detection. For replacement procurement, verify the installed module’s order number, termination unit, channel configuration, and field-load requirements before installation. The AO810V2 is not a HART output module, and it does not provide module-level redundancy.

Field Application & Technical Pitfalls
Typical Applications
1) Control valve positioning
The AO810V2 can provide a 4–20 mA command to a compatible valve positioner. In a typical loop, 4 mA represents the configured lower range and 20 mA the upper range, although the actual engineering units depend on the control-system scaling and positioner configuration.
2) Variable-speed drive references
Where the receiving drive supports an analog current reference, an AO810V2 channel can transmit the commanded speed or another configured setpoint. Verify the drive’s input impedance, scaling, grounding, and signal-loss response before commissioning.
3) Process setpoint transmission
The module can transmit analog commands to compatible process equipment, including devices used in flow, pressure, temperature, and level-control applications. The suitability of each channel depends on the receiving device’s electrical requirements and the control-system configuration.
Three Replacement Pitfalls to Avoid
Pitfall 1: Confusing AO810V2 with AO815 or AO820
These modules are not interchangeable simply because they belong to the S800 I/O family. The provides eight current-output channels without HART. The AO815 supports HART, while the AO820 has a different output arrangement that includes voltage signals. Match the required function and exact order number.
Pitfall 2: Ignoring load resistance and power-supply connections
The permitted output load depends on the documented supply arrangement. A loop that exceeds the supported load may not reach its intended current, even when the controller command is correct. Check the field device, cable resistance, and termination-unit wiring before connecting the loop.
Pitfall 3: Assuming an output error means the module has failed
An incorrect current signal can result from a field wiring fault, missing process supply, excessive load, configuration error, or faulty receiving device. Review the channel diagnostics and measure the loop at appropriate test points before replacing the module.
Field lesson: During a planned shutdown, a maintenance team may replace an analog output module after observing a valve-position discrepancy. If the real issue is excessive loop resistance or incorrect scaling, the replacement will not resolve the fault. Confirming the commanded value, measured current, field wiring, and receiving-device configuration helps isolate the cause before a spare is installed.
Quality Control (QC) SOP & Transparency
Our inspection process for the ABB focuses on model verification, physical condition, and suitability for the intended S800 I/O installation.
- Part-number verification: Check the model marking and order number against and 3BSE038415R1.
- Visual inspection: Examine the circuit board, connector contacts, housing, and mounting interfaces for visible damage, corrosion, contamination, or signs of unauthorized repair.
- Termination-unit compatibility review: Confirm that the intended MTU is supported and that the installation’s field wiring arrangement matches the replacement requirements.
- Functional testing: Where an appropriate test setup is available, verify module startup and output behavior against the applicable documentation. A visual inspection alone is not represented as proof of full operational performance.
- Final QA and packing: Recheck the model, physical condition, and order details before protective packing and shipment.

Frequently Asked Questions
Q1: What is the ABB used for?
It is an eight-channel analog output module for the ABB S800 I/O system. It generates 0–20 mA or 4–20 mA current signals for compatible field devices.
Q2: What is the order number for ?
The ABB order number is 3BSE038415R1. Verify this number against the installed module label before ordering a replacement.
Q3: Does support HART communication?
No. The does not support HART. If the application requires HART communication over the analog loop, verify whether a suitable alternative module, such as the AO815, meets the system requirements.
Q4: Can be used with any termination unit?
No. ABB lists compatible termination units including TU810V1, TU812V1, TU814V1, TU830V1, and TU833. Confirm the exact MTU version and installation arrangement before purchase.
Q5: Does support redundant operation?
No. ABB’s product data identifies the as a non-redundant analog output module. If the application requires redundant output channels or module-level redundancy, select a module designed for that architecture.
Q6: What happens if the output channel detects a fault?
The module provides diagnostics, including output readback verification, open-circuit detection, and process-supply supervision. Its Output Set as Predetermined (OSP) behavior depends on the configured system response. Verify the intended fault-state behavior before commissioning.
Q7: What information should I provide for a quotation?
Provide the complete model and order number, required quantity, preferred condition, and delivery destination. For a replacement, include the existing MTU designation and field-signal requirements to help verify compatibility.
