Compatible Replacement & Equivalent Models
When the DSQC328A is unavailable or end-of-life, the following models are commonly evaluated as replacements. Always verify firmware and RobotWare version compatibility before substitution.
- ABB DSQC652 (3HAC025917-001) – 24 DI / 16 DO, DeviceNet, direct drop-in for most IRC5 applications requiring expanded I/O
- ABB DSQC651 (3HAC025784-001) – 16 DI / 16 DO analog combo module; suitable when analog I/O is also required
- ABB DSQC332A (3HAC17484-1) – earlier-generation equivalent; verify RobotWare 5.x compatibility
- ABB DSQC355A – I/O module with integrated safety relay; applicable in safety-rated cell designs
- Third-party DeviceNet I/O nodes – Turck, Balluff, or Pepperl+Fuchs DeviceNet slaves can substitute in non-safety applications with custom EDS configuration
Note: Konmask.com recommends confirming the replacement part number with your ABB system integrator or our technical team before installation.
Why Choose the Original Model
- Plug-and-play compatibility – factory-configured for IRC5; no EDS file modification required
- Guaranteed firmware alignment – tested against RobotWare 5.x and 6.x releases
- ABB warranty & traceability – full OEM documentation and serial number traceability
- Reduced commissioning risk – eliminates parameter mapping and bus address conflicts common with third-party substitutes
- Long-term spare availability – Konmask maintains stock of genuine and refurbished DSQC328A units for rapid dispatch
Typical Applications
- Automotive body-in-white welding cells (spot & MIG)
- Material handling and palletizing lines
- Machine tending and CNC loading/unloading
- Assembly and press-fit automation
- Paint shop and coating robot systems
- Collaborative cell I/O expansion (IRC5 Compact)
System Compatibility
| Controller | Compatible | Notes |
|---|---|---|
| ABB IRC5 Single Cabinet | ✅ Yes | Primary target platform |
| ABB IRC5 Dual Cabinet | ✅ Yes | Slave cabinet I/O expansion |
| ABB IRC5 Compact | ✅ Yes | Space-constrained installations |
| ABB S4C+ (legacy) | ⚠️ Verify | Bus protocol differences; consult ABB |
| ABB IRC5P (paint) | ✅ Yes | Confirm ATEX zone requirements separately |
| Non-ABB controllers | ❌ Not recommended | DeviceNet node possible but unsupported |
RobotWare Versions: Compatible with RobotWare 5.10 and above. Full feature support confirmed on RobotWare 6.x.
Selection Guide
Use the decision tree below to determine whether DSQC328A is the right module for your application:
- Controller type? → If IRC5 (any variant): proceed. If S4C+: consult ABB or Konmask technical team.
- I/O count required? → 16 DI + 16 DO sufficient: DSQC328A ✅. Need more channels: consider DSQC652.
- Analog I/O needed? → No: DSQC328A ✅. Yes: consider DSQC651 or add a separate analog module.
- Safety-rated I/O required? → No: DSQC328A ✅. Yes: evaluate DSQC355A or ABB SafeMove I/O.
- Budget & lead time? → OEM new: highest cost, longest lead. Konmask refurbished: 30–50% cost saving, same-week dispatch. Third-party equivalent: lowest cost, highest integration effort.

Replacement & Compatibility FAQ
Q: Can DSQC652 directly replace DSQC328A without reprogramming?
A: In most cases yes, but the DeviceNet node address and I/O mapping in RobotStudio must be verified. The physical connector pinout is compatible.
Q: Is a refurbished DSQC328A reliable for production use?
A: Yes. Konmask refurbished units pass the same functional tests as new modules. We provide a 12-month warranty on all refurbished parts.
Q: What is the lead time for a new OEM DSQC328A?
A: In-stock units ship within 1–3 business days. If out of stock, typical OEM lead time is 4–8 weeks. Contact us for current availability.
Q: Can I use a third-party DeviceNet I/O module instead?
A: Technically possible with correct EDS configuration, but ABB does not officially support third-party I/O nodes. This may void your robot warranty and complicate ABB service support.
Q: Do you provide installation support?
A: Yes. Our technical team can provide remote guidance for module swap procedures. Contact [email protected].
