Application-Specific FAQ
Q: Is the KJ3221X1-EA1 compatible with both DeltaV S-Series and M-Series controllers?
A: Yes. This terminal block is designed for the DeltaV field termination architecture and is compatible across DeltaV controller generations. Confirm your specific I/O card pairing with our technical team.
Q: Can this part be used in SIL 2 safety instrumented systems?
A: The terminal block itself is a passive wiring component. SIL suitability depends on the complete safety loop design including the I/O module, logic solver, and field device. Consult your SIS engineer for loop-level SIL verification.
Q: Do you supply new or refurbished units?
A: Both. Condition is clearly stated at time of quotation. All refurbished units are tested and documented. New surplus units are sourced from verified channels with original packaging where available.
Q: What is the typical lead time?
A: In-stock units ship within 1–3 business days. For sourced units, lead time is typically 5–10 business days depending on origin. Emergency orders can be expedited — contact us directly.
Q: Can Konmask provide a Certificate of Conformance (CoC)?
A: Yes. A CoC and test report are available for all units upon request. These documents are provided with the shipment or via email prior to delivery.
