Application-Specific FAQ
Q: Is the 900C52-0021 compatible with Experion PKS R500?
A: Yes. The 900C52-0021 is compatible with Experion PKS R310 through R500 and later. Firmware upgrades may be required for newer releases – contact us for version-specific guidance.
Q: Can this module operate in a non-redundant (simplex) configuration?
A: Yes. A single 900C52-0021 can operate as a standalone controller without a redundant pair, though hot-standby redundancy is strongly recommended for critical process loops.
Q: What is the difference between 900C52-0021 and 900C52-0022?
A: The 900C52-0021 is the primary CPU module; the 900C52-0022 is the redundant (secondary) counterpart. Both are identical in hardware – the role is determined by system configuration in Experion Builder.
Q: Do you provide installation and commissioning support?
A: Konmask.com provides remote technical advisory support for module replacement and integration. On-site commissioning services can be arranged through our partner network.
Q: What warranty is included?
A: All units carry a 12-month warranty covering manufacturing defects. Extended warranty and spare-parts management contracts are available on request.
