I. Product Basic Information  

Model: ACU-01B  

Part Number: 3HNA024871-001 (Upgraded replacement for older model: 3HNA013719-001)  

Origin: Norway  

Compatible Models: ABB IRB5400/IRB5500/IRB580 series electrostatic spray robots (main models used in automotive body painting lines)  

Net Weight / Dimensions: 3.66 kg; 210 (L) × 160 (W) × 140 (H) mm  

ICore Features (3 Independent Pneumatic Closed-Loop Controls)  

Three-channel independent pneumatic closed-loop regulation: PID precise pressure control for atomizing air, shaping air, and turbine drive air—ensuring millisecond-level response, stable paint mist atomization, and consistent spray pattern width to guarantee uniform film thickness and reduce paint consumption.  

Integrated solenoid valve assembly + pressure monitoring: Built-in pressure sensors and high-speed electrically controlled valves enable real-time pressure data acquisition and online adjustment of pressure parameters via robot programming.  

Valve position & fault self-diagnosis: Equipped with status indicator lights to monitor air leakage, blockage, or valve failure in real time; alarm codes can be remotely read via RobotStudio software.  

Bus communication: Built-in RJ45 Ethernet (EtherNet/IP/Profinet), directly connected to the IRC5 robot controller for high-speed exchange of spray recipe parameters.
