Note: Always verify your IRC5 controller firmware version and robot model before substituting part numbers. Contact our team for cross-reference confirmation.
Why Choose the Original Model
- Guaranteed Compatibility: OEM part numbers ensure plug-and-play fit with ABB IRC5 systems — no firmware patching or hardware modification required.
- Calibration Data Integrity: The DSQC561’s battery-backed EEPROM preserves axis calibration offsets, preventing costly re-calibration after replacement.
- Integrated Brake-Release Buttons: The physical buttons on the SMB allow safe manual axis movement during maintenance — a feature absent on generic alternatives.
- ABB Traceability: Genuine parts carry ABB’s manufacturing traceability, supporting warranty claims and service records.
- Long Service Life: Designed to ABB’s industrial-grade reliability standards for 24/7 production environments.
Typical Applications
- ABB IRC5 robot controller maintenance and repair
- Axis position measurement board replacement after failure or damage
- Preventive maintenance stock for high-uptime production lines
- Robot refurbishment and system upgrades
- Automotive, electronics, food & beverage, and general manufacturing automation
- System integrators building or servicing ABB robot cells
System Compatibility
- ABB IRC5 Single Cabinet Controller — All standard robot models (IRB 140, IRB 1600, IRB 2600, IRB 4600, IRB 6640, IRB 6700, etc.)
- ABB IRC5 Compact Controller — Small-footprint installations
- ABB IRC5 Panel Mounted Controller — Integrated panel solutions
- Not compatible with IRC4 or S4C+ controllers — different SMB architecture applies.
Selection Guide
Use the following decision framework to select the correct SMB module for your application:
- Step 1 — Identify your controller: Confirm IRC5 variant (Single Cabinet / Compact / Panel Mounted).
- Step 2 — Check existing part number: Locate the label on your current SMB board. Cross-reference against 3HAC048550-001, 3HAC060919-001, or 3HAC16036-1.
- Step 3 — Verify robot model: Confirm your robot arm model (e.g., IRB 2600, IRB 6700) to ensure axis count and SMB interface match.
- Step 4 — Confirm firmware version: Some SMB revisions require specific RobotWare versions. Contact us with your RobotWare version for confirmation.
- Step 5 — Order: Provide part number, quantity, and delivery urgency. We offer standard and expedited shipping globally.

Replacement & Compatibility FAQ
Q: Can 3HAC16036-1 replace 3HAC048550-001 directly?
A: In most IRC5 systems, yes — these are revision-level equivalents. However, we recommend confirming your RobotWare version. Contact our team for a free compatibility check.
Q: Is the DSQC561 compatible with IRC4 controllers?
A: No. IRC4 uses a different SMB architecture. The DSQC561 is exclusively for IRC5 systems.
Q: Do I need to re-calibrate the robot after replacing the SMB?
A: Yes, robot calibration (fine calibration) is typically required after SMB replacement, as calibration data is stored on the board’s battery-backed memory.
Q: Can you supply both new and refurbished units?
A: Yes. We offer new OEM units and certified refurbished units. Please specify your preference when ordering.
Q: What is the lead time for DSQC561?
A: Standard orders ship within 3–7 business days. Expedited options available — contact us for details.
