Replacement & Compatibility FAQ
Q: Is CL6827X1-A1 the same as 12P1392X042?
A: Yes — 12P1392X042 is the Emerson catalog part number for the CL6827X1-A1 module. Both refer to the same physical unit.
Q: Can I use a CL6827X1-B1 as a direct replacement?
A: In most cases yes, but confirm the hardware revision is accepted by your controller firmware. Contact us for a compatibility check.
Q: Do you supply new or refurbished units?
A: Both. New OEM stock and fully tested refurbished units are available. Condition is clearly stated on each listing.
Q: What is the lead time?
A: In-stock units ship within 1–3 business days. Out-of-stock items typically have a 2–6 week lead time depending on sourcing.
Q: Can this module be used in a DeltaV system?
A: No — the CL6827X1-A1 is designed for PROVOX/RS3 architecture. For DeltaV, Emerson offers dedicated I/O cards. We can assist with the correct DeltaV equivalent.
