ABB 3HNA007026-001 Pendant Power Relay Unit – IRC5 Robot Controller Series
When a Pendant Power Relay Unit fails on an ABB IRC5 robot controller, the entire production line comes to a halt. The teach pendant loses power, safety interlocks become unreliable, and operators are left unable to jog, program, or recover the robot arm. In high-throughput automotive, electronics, and metal fabrication environments, every minute of unplanned downtime translates directly into lost revenue and missed delivery commitments. The ABB 3HNA007026-001 PPRU is the critical bridge between the controller cabinet and the FlexPendant — without it, the robot simply cannot be safely operated or maintained.
The 3HNA007026-001 is ABB’s 3-channel PPRU variant designed for IRC5 single-cabinet and multi-cabinet configurations that do not require an integrated CPU on the relay board itself. Within the IRC5 ecosystem — ABB’s most widely deployed robot controller platform globally — this module manages pendant power switching, emergency-stop relay logic, and enabling-device signal routing across three independent channels. Its architecture reflects ABB’s commitment to IEC 62061 and ISO 13849-1 functional safety standards, making it a non-negotiable component in any certified robot safety circuit.

Key Features & Benefits
- 3-Channel Safety Relay Architecture: Provides redundant pendant power switching for enhanced safety circuit integrity in IRC5 installations.
- No CPU Dependency: The W/O CPU design simplifies replacement logistics — no firmware flashing or CPU pairing required during swap-out.
- Direct Drop-In Replacement: Engineered to OEM specifications for seamless installation without cabinet modification.
- Emergency-Stop Signal Routing: Manages E-stop relay logic between the FlexPendant and the main safety board, ensuring compliant robot halting behavior.
- Enabling Device Interface: Supports the 3-position enabling device (deadman switch) signal path required for safe manual operation modes (T1/T2).
- Reduced Downtime: Stocking this module as a critical spare eliminates multi-week lead times from OEM channels during emergency breakdowns.
Industry & Equipment Applications
- Automotive Manufacturing: Welding, painting, and assembly robots in body-in-white and powertrain lines.
- Electronics & PCB Assembly: Pick-and-place and soldering robot cells requiring precise pendant control.
- Metal Fabrication: Arc welding and plasma cutting robots with frequent teach-pendant interaction.
- Foundry & Die Casting: High-temperature environments where controller components face accelerated wear cycles.
- Logistics & Palletizing: High-cycle palletizing robots in distribution centers running 24/7 operations.
- Food & Beverage: Hygienic robot cells where safety circuit integrity is subject to regulatory audit.

Frequently Asked Questions
- Q: What is the difference between the PPRU with CPU and without CPU (W/O CPU)?
- A: The W/O CPU variant (3HNA007026-001) contains only the relay and power switching circuitry. The CPU-integrated variant includes an onboard processor for additional safety logic. The correct variant depends on your specific IRC5 cabinet configuration — check your cabinet’s wiring diagram or contact us for guidance.
- Q: Is this part compatible with all IRC5 robot models?
- A: The 3HNA007026-001 is designed for IRC5 single-cabinet and multi-cabinet controllers. Compatibility with specific robot models (IRB 1600, IRB 2600, IRB 6700, etc.) depends on the controller revision. Please provide your robot serial number when inquiring.
- Q: Do you offer a warranty on this module?
- A: Yes. We offer a standard 90-day functional warranty on all tested and refurbished units. New OEM units carry the manufacturer’s warranty terms.
- Q: Can you ship to my country?
- A: We ship globally. Contact us with your destination country and we will provide shipping options, estimated transit times, and any applicable export documentation requirements.
- Q: What if the module I receive does not resolve my fault?
- A: Our technical team can assist with IRC5 fault diagnosis. If the PPRU is confirmed not to be the root cause, we offer a return and exchange process — contact support@konmask.com within 7 days of receipt.
