Warranty: 365 days coverage.
Lead time: 1 week if in stock; no more than one month at the latest.
Payment: 50% advance payment; full payment prior to delivery.
Express delivery: FedEx, UPS, DHL.
Designed for ABB IRC5 cabinets – Integrates with the controller backplane for reliable system communication.
Stable I/O handling – Manages internal control and expansion signals, supporting typical line automation needs.
Drop-in replacement – Mechanically and electrically compatible with the intended slot, which typically reduces downtime.
Service-friendly – Board-level replacement approach; you might notice maintenance becomes faster compared with rewiring external I/O.
Industrial-grade build – Engineered for cabinet environments, usually 24 VDC logic ecosystems found in ABB controllers.
Broad application fit – Works across material handling, welding, machining cells, and general assembly where IRC5 is deployed.
ESD-safe replaceability – Designed for controlled swap-outs during planned maintenance or urgent repairs.
| Brand / Model | ABB DSQC626 (3HAC026289-001) |
| HS Code | 853890 (Parts for electrical control equipment) |
| Power Requirements | Backplane-supplied; 24 VDC logic supply typical within IRC5 cabinet power distribution |
| Operating Temperature | 0 to +55 °C (typical cabinet environment for controller electronics) |
| Communication Interfaces | IRC5 controller backplane interface; internal ribbon/board-to-board connectors as per controller revision |
| Signal I/O Types | Internal control and I/O expansion signaling within the IRC5 system (not a standalone field I/O block) |
| Installation Method | Plug-in board for IRC5 controller slot; screw/retainer fixation; ESD-safe handling required |
| Compatibility | Intended for ABB IRC5 systems; specific use may depend on controller options and firmware |
You’ll typically find the DSQC626 in automated lines where ABB IRC5 robots are used. Common scenarios include:
Automotive body-in-white cells: coordinating weld cells and tooling interlocks.
Material handling and palletizing: synchronizing infeed/outfeed conveyors and sensors.
Machine tending: linking robot logic to CNC ready signals and door interlocks.
General assembly and packaging: managing light curtains, stack lights, and station handshakes.
Reliability: Stable performance in most cabinet environments; seems to be a common fix for intermittent I/O behavior.
Compatibility: Built for IRC5 ecosystems, reducing the risk of mismatched connectors or unsupported firmware.
Cost & Downtime: A direct board swap is often quicker and more economical than reworking external I/O hardware.
Supportability: Technicians familiar with IRC5 typically recognize the DSQC-series layout, which speeds troubleshooting.
Simulated customer feedback: “Replacing the DSQC626 cut our fault tracing time from hours to minutes. The robot was back in cycle before the next shift.”
Installation & MaintenanceEnvironment: Install in a clean, ventilated IRC5 cabinet. Keep ambient within 0–55 °C and avoid condensation.
Power-down & ESD: Fully power down and lock out the controller. Use an ESD wrist strap and handle the board by edges.
Wiring & Seating: Verify backplane alignment; secure fasteners as specified. Check ribbon and board-to-board connectors for proper seating.
Backups: Back up RobotWare configuration and I/O settings before hardware changes—this typically prevents mismatch alarms.
Routine care: Quarterly dust removal with dry, clean air; inspect connectors for oxidation; confirm firmware/options alignment after replacement.
Certifications: CE-conform cabinet integration; components and manufacturing commonly meet ISO 9001 and RoHS requirements.
Safety: Designed for use inside certified ABB IRC5 systems; follow ABB service manuals for compliance.
Warranty: 365-day warranty (standard for this spare part offering).
For maintenance planning, teams often pair the DSQC626 with other IRC5 boards and peripherals to stabilize a whole cabinet:
DSQC639 – Main computer board for IRC5 controllers.
DSQC679 – Axis computer board for motion control.
SMB units (various DSQC-series) – Resolver/encoder interface boards in the robot base.
FlexPendant (various 3HAC-series models) – For operator interaction and diagnostics.
Note: Exact use and slot position can depend on controller variant and option package. If you share the controller cabinet code and RobotWare version, we can double-check compatibility before shipping.
