Replacement & Compatibility FAQ
Q: Can I replace 133388-01 with 133388-02 without reconfiguring the rack?
A: In most cases yes, but you should re-upload your RCS configuration file after swapping to ensure all parameters are correctly applied. Consult the Bently Nevada 3500/53 manual for revision-specific differences.
Q: Is the 3500/53 compatible with third-party speed sensors?
A: The module supports standard passive magnetic pickups and active proximity probes meeting Bently Nevada input specifications. Third-party sensors must be verified against the module’s input impedance and signal level requirements.
Q: Does Konmask.com supply refurbished units?
A: We supply both new OEM units and professionally tested surplus units. All surplus units undergo functional testing and are clearly labeled. Contact us to specify your preference.
Q: Can this module be used as a standalone overspeed trip device?
A: No. The 3500/53 is designed to operate within the Bently Nevada 3500 rack system and relies on the rack backplane for power and communication. It is not a standalone device.
Q: What is the typical lead time for a replacement unit?
A: In-stock units ship within 1–3 business days. For sourced or refurbished units, lead time is typically 5–15 business days. Contact us for real-time stock status.
