ABB AO810V2 (3BSE038415R1) – 8-channel analog current output module for S800 I/O

The ABB AO810V2 is a reliable 8-channel analog output module for the S800 I/O platform, typically used to drive 0/4–20 mA current loops in process control. From my experience, it drops neatly into existing S800 stations and just works—ideal when you’re expanding a line, replacing a failed AO card, or standardizing spares across multiple plants. You might notice that it pairs especially well with AC 800M-based systems in 800xA environments, keeping engineering and maintenance consistent across sites.

Key Features

• 8 current output channels – Designed for 0/4–20 mA loops to drive valves, positioners, and converters.
• S800 I/O platform compatibility – Mounts on TU8xx MTUs and integrates on the S800 ModuleBus, so no special wiring tricks.
• Configurable per channel – Channels can typically be set for 0–20 mA or 4–20 mA depending on your control strategy.
• Diagnostics and status LEDs – You get quick visual feedback on module health; helps with faster loop checks in commissioning.
• Compact, serviceable design – Hot-swappable within the S800 station in many cases, minimizing downtime during replacement.
• Stable loop drive – Steady output under load for consistent actuator behavior across varying field conditions.

Application Fields

The AO810V2 typically ends up in process and discrete plants where stable current loops are mandatory:

• Refining & petrochemical – Control of control valves, positioners, and I/P transducers.
• Water & wastewater – Dosing pumps and actuator drives with 4–20 mA signals.
• Power & utilities – Governor setpoints, damper actuators, and feedwater control loops.
• Food & beverage / pharmaceuticals – Clean dosing and temperature control skids needing reliable current outputs.
• Pulp & paper / metals – Speed and tension setpoints for drives requiring analog command.

“Swapped an AO810V2 into a mixed S800 rack during a shutdown. Channel mapping stayed consistent, loop checks were straightforward, and we were back up in under an hour.” — Maintenance Supervisor, regional water plant

Advantages & Value

• Reliability – Proven in the ABB S800 ecosystem; stable loop drive that keeps actuators on target.
• Compatibility – Works with common TU8xx MTUs and AC 800M-based systems, reducing engineering time.
• Cost control – Straightforward drop-in replacement limits downtime and spare parts complexity.
• Serviceability – Hot-swap in many S800 stations; quick LED diagnostics help during commissioning.
• Scalability – 8 channels per card makes it easy to add outputs without redesigning cabinets.

Installation & Maintenance

• Cabinet & mounting – Install on DIN-rail using the appropriate TU8xx MTU. Keep the cabinet well-ventilated and within 0…+55 °C.
• Wiring – Terminate 0/4–20 mA loops on the MTU terminals. Maintain a solid common and segregate analog wiring from power and high-frequency lines.
• Grounding – Follow ABB S800 grounding rules; in many cases channels share a common return, so plan loop isolation externally if required.
• Commissioning – Configure channel ranges in the engineering tool, then perform loop calibration with a traceable milliamp source.
• Maintenance – Periodic loop checks (e.g., semi-annually) and terminal re-torque help prevent drift or intermittent faults. Firmware and configuration backups should be kept with the asset records.
• Safety – De-energize the station before inserting/removing the module unless your installation explicitly supports hot-swap procedures.

Quality & Certifications

• CE compliant
• cULus certification (typical for S800 I/O modules)
• RoHS/REACH compliant (manufacturer statements for S800 I/O series)
• Manufacturer warranty: typically 12 months; we provide 365 days warranty on supply

If you’re standardizing on ABB S800 I/O, the AO810V2 seems to be the sensible choice for current-driven actuators. One thing I appreciate is how predictable it is during loop checks—saves time when you’re under a tight shutdown window.
