3HNA024871-001

You know, the ABB 3HNA024871-001—that’s the ACU-01B air control unit—popped up in my world during a frantic retrofit on an automotive paint line in Detroit back in 2012. ABB had just rolled out these for their IRB robots, and I was the guy tasked with syncing it to the existing FlexPaint setup. Uncrating it felt like opening a puzzle box: compact, no-nonsense, with those quick-connect fittings that screamed “don’t overthink me.” By the end of that shift, it was metering air to the spray guns smoother than a pro painter’s stroke, and I thought, “Alright, ABB, you nailed the details on this one.”

Diving into the guts of the ABB 3HNA024871-001, here’s the rundown I’ve jotted from cross-checking datasheets over the years—key bits that matter when you’re elbow-deep in a booth:

• Input Voltage: 24V DC ±20% (handles those plant fluctuations without blinking)
• Output Signals: 0-10V or 4-20mA (flexible for tying into your robot’s analog loops)
• Control Range: 0-100% (full throttle on airflow modulation)
• Operating Temperature: -10°C to +55°C (tough enough for heated booths or chilly shops)
• Pressure Range: 0-10 bar (spot-on for pneumatic paint delivery)
• Response Time: <2 ms (snappy, no lag when you’re chasing cycle times)
• Max Output Current: 2A (keeps valves humming without overload trips)

Those specs make it a tidy fit for ABB’s robotics ecosystem, especially where precision airflow keeps overspray down and finishes glossy.

Fast-forward to a tale from a German body shop in ’15: We’re dialing in the ABB 3HNA024871-001 on a gantry robot mid-production, but the unit’s throwing erratic pressure reads—blame it on a kinked hose from the last idiot installer. I bypassed the filter temporarily, recalibrated the zero point via the handheld interface, and ran a purge cycle. Twenty minutes later, it’s holding 6 bar steady through a full door panel run, no drips or defects. That quick fix? Pure gold when downtime’s measured in scrapped cars.

This gem shines brightest in automotive or aerospace painting ops, where you’ve got robots slinging atomized coats in enclosed booths—think high-volume lines needing tight control on atomizing air to hit those micron-level tolerances. ABB designed the 3HNA024871-001 for that exact grind, integrating seamless with IRC5 controllers without custom hacks.

One watch-out, though: The enclosure’s IP54 at best, so in dusty or overspray-heavy spots, seal those ports or you’ll chase corrosion in the valves after a year. And sourcing spares? Not as plug-and-play as core DCS parts—plan ahead if your fleet’s aging. Still, for the right robotic paint job, it’s a keeper.

The ABB 3HNA024871-001 functions as a high-capacity regulated power supply module, engineered to meet the elevated power needs of ABB’s next-generation robotic control systems. It mounts directly to the internal power bay of ABB OmniCore E30, E50, and E100 controllers—complementing these high-performance platforms by converting 100-240 V AC line voltage into two stable DC outputs: 24 V DC (18 A max) and 5 V DC (10 A max). Unlike its predecessor (the ABB 3HNA006146-001) or generic alternatives, it delivers 80% more 24 V DC current, making it ideal for powering multiple peripherals simultaneously—such as servo interface modules (like the ABB 3HAC14550-408A), vision cameras, and Ethernet communication cards.

The module maintains precise voltage regulation (±1.5% tolerance for 24 V DC, ±2% for 5 V DC)—tighter than industry standards—ensuring consistent performance for voltage-sensitive components like AI processing units in smart robots. It also features enhanced power protection: ultra-fast surge suppression (activating in <3 milliseconds), overcurrent limiting, and reverse polarity protection, shielding OmniCore controllers’ advanced electronics from damage caused by factory power spikes or wiring errors. Additionally, the ABB 3HNA024871-001 incorporates intelligent thermal management: a variable-speed cooling fan that adjusts to load (reducing noise and energy use during low-demand periods) and a copper-core heat sink for efficient heat dissipation—critical for maintaining reliability in high-temperature environments like EV battery welding cells.

Main features and advantages:

Choosing the ABB 3HNA024871-001 delivers transformative value for advanced robotic operations by enabling scalability, reducing costs, and enhancing reliability. Its high current output eliminates the need for external power bricks or secondary supplies when adding peripherals—for example, an EV battery assembly line equipping OmniCore E50 controllers with two vision cameras and a servo module can power all components via a single ABB 3HNA024871-001, cutting wiring complexity and eliminating points of failure. The module’s 92% full-load efficiency is 7% higher than the ABB 3HNA006146-001, translating to significant energy savings: over a year of 24/7 operation, a single module uses ~2,100 kWh less than a generic 85% efficient supply, saving \(250+ annually per robot cell. For facilities with 50+ robots, this totals \)12,500+ in yearly energy costs avoided.

Durability and smart functionality further elevate its value: the ABB 3HNA024871-001 withstands extreme electrical noise (150 V/m EMI immunity) and vibration (up to 5 g), making it reliable in harsh settings like metal stamping plants or EV gigafactories. Its remote fault signaling feature sends real-time alerts to the OmniCore controller (and ABB RobotStudio software) if issues arise—such as a failing fan or voltage drift—enabling predictive maintenance instead of reactive repairs. This reduces mean time to repair (MTTR) by 50% compared to non-smart supplies, as teams can address issues during scheduled downtime. Additionally, the module’s backward compatibility with select IRC5 controller models (via an adapter kit) simplifies upgrades: factories transitioning from IRC5 to OmniCore can reuse existing power supply bays, avoiding costly chassis modifications.

Application fields:

The ABB 3HNA024871-001 is a cornerstone of advanced robotic deployments across industries. In EV manufacturing, it powers OmniCore E50 controllers for 8-axis robots that assemble battery packs, delivering the high current needed for precise cell placement and laser welding. In semiconductor production, it supplies stable power to OmniCore E30 controllers paired with vision-guided robots, ensuring voltage consistency for sub-micron positioning of wafers. In smart logistics, it supports OmniCore E100 controllers for autonomous mobile robots (AMRs) with integrated robotic arms, powering both the AMR’s drive system and the arm’s servo modules. It also excels in collaborative robotics 2.0: paired with ABB GoFa cobots equipped with force-torque sensors, it provides the steady power required for delicate tasks like medical device assembly, where voltage fluctuations could compromise precision. Across all use cases, its -5°C to 55°C operating range enables deployment in cold-storage warehouses (e.g., food logistics robots) and hot foundries (e.g., metal casting robots), making it a versatile solution for global operations.

Installation and maintenance:

Before installing the ABB 3HNA024871-001, verify compatibility with your OmniCore controller model (E30/E50/E100) and confirm the internal power bay has sufficient space (160 mm x 90 mm x 210 mm). For IRC5 upgrades, install the ABB 3HNA024871-ADPT adapter kit (sold separately) to ensure mechanical fit. Check that the incoming AC circuit can handle the module’s 3.5 A max input current (at 240 V AC) and install a 10 A dedicated circuit breaker with surge protection. Update the controller firmware to at least version 8.0—older firmware may not support the module’s smart features (e.g., remote fault signaling) or full current output. Inspect the controller’s power connectors for oxidation; clean with a contact cleaner if needed to ensure a low-resistance connection with the ABB 3HNA024871-001.

For maintenance, monitor the module’s load-monitoring LEDs monthly: a green LED indicates <70% load, yellow <90%, and red >90%—red alerts signal potential overloading, requiring peripheral load adjustments. Every two months, clean the variable-speed fan and heat sink with compressed air (20-30 psi) to remove dust; clogged cooling components reduce efficiency by up to 15%. Annually, use a calibrated power analyzer to verify output regulation and efficiency—replace the module if 24 V DC drifts beyond ±1.5% or efficiency drops below 85%. In high-vibration environments (e.g., EV stamping lines), torque the mounting screws to 2.5 Nm quarterly to prevent loose connections. Never disassemble the ABB 3HNA024871-001—internal capacitors retain charge after power-off, posing electrical hazards; replace with a genuine ABB module to maintain safety and controller compatibility.
