Application-Specific FAQ
Q: Can the PR6423/XXX/X4X CON021 replace an older PR6423 variant with a different sub-code?
A: In many cases yes, provided the connector type (CON021) and output voltage match. However, cable length and connector orientation sub-variants (XXX, X4X) must be verified against your system drawing. Contact us for cross-reference support.
Q: Is this module compatible with Bently Nevada 3500 series racks?
A: No. The PR6423 series is an EMERSON EPRO proprietary module and is not interchangeable with Bently Nevada hardware. Ensure your rack is an EPRO PR6426 chassis before ordering.
Q: Do you supply the CON021 connector separately?
A: Yes. CON021 connector sets are available as a separate line item. Include this in your enquiry if your existing connector is damaged.
Q: What is the lead time for new-in-box stock?
A: New-in-box availability varies. Tested surplus units typically ship within 1–2 business days. NIB units may require 5–15 business days depending on factory allocation. Contact us for current stock status.
Q: Can Konmask provide a certificate of conformance (CoC)?
A: Yes. A CoC and functional test report are available upon request for all tested units at no additional charge.
