Description
ABB 3HNA024871-001 ACU-01B Air Control Unit
Product Overview
Paint-robot downtime is not always caused by the robot controller itself. A fault in the pneumatic control section can interrupt spraying even when the IRC5 controller and robot axes remain operational. The ABB 3HNA024871-001 is the ACU-01B Air Control Unit, intended for ABB robotic painting applications where controlled air functions form part of the spray process. ABB identifies ACU-01B under its Robotics spare-parts portfolio, while ABB-related catalog information identifies it as an air-control module with three-channel/Ethernet catalog information.
For maintenance teams, the important point is that ABB 3HNA024871-001 is an application-specific robot component, not a general-purpose PLC analog or pneumatic I/O module. It has also been documented as the replacement for the earlier 3HNA013719-001 ACU-01. Before installation, match the complete ABB article number, communication mode, robot/controller configuration, connectors, and pneumatic arrangement. ABB-related documentation specifically warns that communication mode must be considered when replacing the spare.

The catalog description and replacement relationship are better supported than the electrical and pneumatic figures circulating through secondary listings. I therefore would not publish 24 VDC, 10 bar, 100/200 L/min, or specific analog signal ranges as confirmed specifications without the applicable ABB technical document for the exact configuration.
Application Scenarios & Field Considerations
ABB Paint Robot Systems
The ACU-01B is associated with ABB robotic painting applications, particularly spray-robot configurations. It belongs to the specialized equipment surrounding the robot’s coating process rather than the general IRC5 PLC/I/O architecture.

Pneumatic Spray Control
A failure in an air-control unit can present as a process problem—poor atomization, incorrect spray behavior, or an inability to execute the intended coating sequence—rather than as a conventional controller fault. Diagnosis should therefore include the pneumatic circuit, valves, sensors, wiring, and ACU configuration.
Legacy Robot Maintenance
The replacement relationship with 3HNA013719-001 ACU-01 makes the ACU-01B relevant to maintenance of older ABB painting installations. Do not assume that every ACU-01 installation can accept the newer unit without checking communication mode and system documentation.
Planned Spare Holding
For a production paint line, this is the type of application-specific spare where the complete material number matters. A visually similar ABB module is not sufficient evidence of interchangeability.

Engineer’s Guide — Field Pitfalls to Avoid
1. Do not treat as generic PLC I/O.
Its job is tied to ABB’s robot painting architecture. Replacing it with a generic pneumatic controller does not establish functional compatibility.
2. Check communication mode before commissioning.
ABB-related product information specifically notes that communication mode must be considered when replacing the spare. A mechanically compatible installation can still fail at system integration if the communication configuration is wrong.
3. Match the complete part number.
Use 3HNA024871-001, not simply “.” The full material number provides the procurement-level identification needed when dealing with legacy ABB robot equipment.
4. Verify the pneumatic arrangement.
Do not assume that air-port configuration, valve arrangement, tubing, or process connections are identical simply because the electronic module has the same model designation.
5. Confirm the old unit’s configuration before removal.
Record connectors, communication settings, wiring, pneumatic connections, and controller-side configuration. This is especially important when maintaining an older paint cell with undocumented modifications.
6. Do not copy secondary specifications blindly.
Online listings disagree on supply voltage, pressure, flow, dimensions, and even the functional description. For an engineering replacement, the ABB documentation and the physical nameplate should take precedence.
FAQ
Is ABB 3HNA024871-001 a PLC module?
No. It is identified as an Air Control Unit for ABB Robotics applications. It should not be classified as a conventional PLC CPU, digital I/O module, or general-purpose communication card.
What is the difference between 3HNA024871-001 and 3HNA013719-001?
ABB-related catalog information identifies 3HNA013719-001 as the earlier , with 3HNA024871-001 identified as the replacement. Replacement should still be checked against the installed robot configuration and communication mode.
Is 3HNA024871-001 used with ABB IRC5?
It is associated with ABB robot systems and paint-robot configurations, including records referencing IRC5P. Exact controller and robot compatibility should be checked against the machine’s ABB configuration rather than inferred solely from the IRC5 family name.
Can I use the on any ABB paint robot?
No. The part number alone is not enough to establish universal compatibility. Check the robot model, controller generation, communication mode, pneumatic arrangement, connectors, and installed software/configuration.
What voltage does 3HNA024871-001 use?
Secondary listings publish different values, including 24 VDC, but I would not treat that as an engineering-grade verified specification without the applicable ABB documentation for the exact unit. The physical nameplate and machine electrical drawings should be used for final confirmation.
What should I verify when buying a replacement?
At minimum, verify 3HNA024871-001, designation, hardware/revision markings, communication mode, connector condition, pneumatic connections, and the target robot/controller configuration. For used equipment, verify actual inventory condition rather than relying on a stock photograph.
Is the interchangeable with a visually similar ABB module?
Not automatically. ABB robot spare parts are configuration-sensitive. A similar enclosure or connector arrangement does not prove functional interchangeability.
