Selection Guide
Use this guide to confirm the correct operating panel for your REF542plus system:
- Step 1 — Identify relay model: Confirm your relay is ABB REF542plus (not REF541, REF543, or REF545).
- Step 2 — Check hardware revision: Locate the relay nameplate; note the hardware revision (e.g., Rev. D, Rev. E). Panel compatibility may vary by revision.
- Step 3 — Verify firmware version: Panels with updated firmware may require a matching HMI version. Consult ABB document 1MRS750889-MUM.
- Step 4 — Confirm mounting dimensions: Standard REF542plus panel cutout is required. Measure existing cutout before ordering.
- Step 5 — Contact Konmask: Send your relay nameplate photo and current panel P/N to support@konmask.com for final confirmation.

Replacement & Compatibility FAQ
Q: Can I use a REF541 or REF543 panel as a replacement?
A: No. The REF542plus operating panel is model-specific. REF541/543/545 panels use different connectors and firmware — they are not interchangeable.
Q: Is the 2RCA029395 panel available new or only refurbished?
A: We stock both new and professionally refurbished units. Specify your preference at checkout or in your inquiry email.
Q: How long does shipping take?
A: Standard international express (DHL/FedEx) typically delivers within 3–7 business days from China.
Q: Can Konmask provide the ABB REF542plus relay itself, not just the panel?
A: Yes. Contact us with your full BOM or relay model for a complete system quote.
Q: Do you provide a certificate of conformity or test report?
A: Available on request for new units. Refurbished units include inspection reports.
