ABB ACU-01B (3HNA024871-001) Air Control Unit for IRC5P Painting Robot

Description

ABB ACU-01B (3HNA024871-001) Air Control Unit for IRC5P Painting Robot

Product Description

The ACU-01B, order code 3HNA024871-001, is an Air Control Unit dedicated to ABB IRC5P paint robots (IRB5500 painting robot series). It replaces the older PPRU/MAC unit, precisely regulating air pressure, paint flow and atomizing air for the spray gun. The unit integrates precision pneumatic proportional valves, pressure sensors, control electronics and communication interface. It receives setpoints from the IRC5 robot controller, executes closed-loop air pressure control, and feeds back measured pressure, flow and fault status back to the robot system. It supports pre-calibration and on-site fine tuning, ensures consistent coating quality and stable spraying parameters. It is installed directly on the robot arm and is a critical spare part for automotive paint shop robot systems.
