Selection Guide
Use this guide to determine whether HIEE405246R0002 UNS0867a-P is the right part for your application:
- Step 1 – Identify your controller model: Confirm AC800M series and CPU module
- Step 2 – Check revision compatibility: R0002 vs R0001/R0003 — match to installed firmware
- Step 3 – Verify slot position: Extension cards occupy specific backplane slots; confirm slot assignment
- Step 4 – Confirm interface type: UNS0867a-P suffix indicates specific interface variant — do not substitute without verification
- Step 5 – Request datasheet: Contact Konmask for the full ABB technical datasheet and wiring diagram

Replacement & Compatibility FAQ
Q: Can HIEE405246R0001 replace HIEE405246R0002?
A: In many cases yes, but firmware and backplane revision must be verified. Contact us for a compatibility check.
Q: Is the UNS0867a-P suffix critical?
A: Yes. The suffix denotes a specific hardware variant. Substituting a non-P variant may cause communication errors.
Q: Do you supply new or refurbished units?
A: Both. All units — new or refurbished — pass functional testing. Condition is clearly stated on your invoice.
Q: What is the lead time?
A: In-stock units ship within 1–3 business days. Out-of-stock items typically have a 2–4 week lead time.
Q: Can you provide the ABB datasheet?
A: Yes. Request it via email and we will provide the official ABB technical documentation.
