Application-Specific FAQ
Q: Is the A6500-RC compatible with all DeltaV controller generations?
A: The A6500-RC is designed for the DeltaV I/O subsystem architecture. Compatibility depends on the specific DeltaV version and carrier hardware. Contact us with your system configuration for confirmation.
Q: Can this relay card be used in SIL-rated safety loops?
A: Safety Integrity Level (SIL) suitability depends on the complete safety loop design and Emerson’s SIL certification documentation for this specific module. Consult your functional safety engineer and Emerson’s TÜV-certified SIS documentation.
Q: Do you supply the matching I/O carrier or subsystem chassis?
A: Yes. Konmask.com stocks a range of DeltaV I/O carriers and subsystem components. Contact us with your full BOM for a consolidated quote.
Q: What is the difference between a new and refurbished unit?
A: We clearly indicate unit condition (new, surplus-new, or refurbished) in the product listing and order confirmation. All units pass our QA inspection regardless of condition grade.
Q: Can you provide an Emerson factory test certificate?
A: Factory test certificates are available for new units sourced directly from authorized channels. For surplus units, we provide our own inspection report. Contact us for documentation requirements.
