System Compatibility
The 3500/93 135785-01 Display Unit is designed exclusively for use within the Bently Nevada 3500 Series Machinery Protection System rack architecture. It is not compatible with the 3300, 3701, or Orbit 60 Series without additional interface hardware.
- ✅ Compatible: 3500 Series Rack (all standard 19-inch chassis)
- ✅ Compatible: 3500/15 Power Supply Module
- ✅ Compatible: 3500/22M Transient Data Interface
- ⚠️ Conditional: 3500/92 Communication Gateway (verify firmware revision)
- ❌ Not Compatible: 3300 Series, Orbit 60 Series (different backplane architecture)
Selection Guide
Use the following decision framework to determine whether the 3500/93 135785-01 is the right module for your application:
- Confirm Rack Series: Is your existing rack a 3500 Series chassis? If yes, proceed. If no, contact Konmask for cross-series alternatives.
- Identify Display Requirement: Do you need local operator display at the rack face? The 3500/93 provides this; if remote HMI only is required, consider the 3500/92 Communication Gateway instead.
- Check Firmware Revision: Retrieve the rack firmware version from the System Manager software. Confirm the display unit firmware is compatible (Rev 3.xx or later recommended).
- Assess Condition Requirement: For critical SIL-rated loops, specify New OEM. For non-critical monitoring or budget-constrained projects, Tested Surplus may be acceptable.
- Quantity & Lead Time: For single-unit emergency replacement, Konmask typically ships within 1–3 business days from verified stock. For project quantities (>5 units), request a formal quotation.

Replacement & Compatibility FAQ
Q: Can the 3500/93 135785-01 replace the 135785-02?
A: In most cases yes — both are 3500/93 Display Units with minor revision differences. Confirm firmware compatibility with your rack’s System Manager software before hot-swapping.
Q: Is this module compatible with the Bently Nevada System 1 software?
A: The 3500/93 Display Unit provides local display only. System 1 connectivity is handled via the 3500/92 Communication Gateway, not the display unit.
Q: Can I use a refurbished unit in a SIL-rated application?
A: This depends on your site’s functional safety management plan. Consult your safety engineer. Konmask can provide full test documentation to support your assessment.
Q: What is the lead time for new OEM units?
A: Typically 1–3 business days for in-stock units. Extended lead times may apply for factory-new OEM orders. Contact us for current availability.
Q: Do you offer exchange / core return programs?
A: Yes. Contact support@konmask.com to discuss exchange pricing if you have a faulty unit to return as core.
