Product Introduction & Supply Chain Strategy
The Bently Nevada 3500/60 is a 6-channel temperature monitor that processes inputs from Resistance Temperature Detectors (RTDs) and thermocouples to safeguard bearings, windings, and lube oil loops. It continuously evaluates thermal drift against configured alert and danger thresholds to initiate automatic trip signals before bearing wiping or thermal breakdown occurs.
Keeping this card in buffer stock mitigates critical supply chain lead times during unexpected thermal faults. Investing in a genuine New Surplus 3500/60 guarantees pristine backplane gold pin contacts, zero component aging, and full factory thermal accuracy to protect plant assets across a 10–15 year operational lifecycle.

Installation & Configuration Guide
Stage 1: Pre-Installation (Prep & Safety)
- Execute lockout/tagout procedures on machinery trip contacts linked to the 3500 relay modules.
- Wear an anti-static wrist strap properly grounded to the enclosure frame.
- Connect via 3500 Rack Configuration Software and export an archive file of the active configuration (
.350file). - Record sensor type selections (e.g., 100 Ω Pt RTD vs Type K TC), scale ranges, and rear I/O terminal wiring configurations.
Stage 2: Removal
- Loosen the upper and lower captive screws on the existing 3500/60 main module faceplate.
- Unlatch both ejector handles simultaneously to release the card edge connectors from the 3500 backplane.
- Slide the card smoothly out along the card guide slots and immediately place it inside an anti-static bag.
Stage 3: Installation (Clone & Seat)
- Verify the replacement 3500/60 module hardware revision matches the original unit.
- Align the printed circuit board edges with the designated slot guide rails in the 3500 rack.
- Push the module firmly inward until it fully seats into the backplane, close the ejector levers, and tighten the captive retention screws.
Stage 4: Power-On & Testing
- Re-apply 24 V DC system power to the 3500 rack power supply modules.
- Confirm the front panel OK LED lights solid green and the TX/RX LED flickers during backplane data polling.
- Connect a decade box or thermocouple calibrator to verify channel scaling and alarm setpoint responses before clearing software bypasses.
Firmware/Software Versions & Upgrade Notes
- Recommended Firmware: Firmware Revision 1.12 or later (configured using 3500 Rack Configuration Software v4.0 or higher).
- Compatibility Notice: Ensure the 3500/60 firmware matches the installed rear I/O module (e.g., RTD/TC Internal Termination I/O, External Termination I/O, or Isolated I/O). Selecting an incorrect I/O card type in the software project will trigger a hardware configuration mismatch fault.
- Upgrade/Downgrade Risk Warning: Do not re-flash firmware while the monitored asset is operating. Flashing forces the 3500/60 module into reset, driving analog outputs to 0 mA and opening the system OK relay, which can cause an unexpected unit trip if the slot is not placed in software bypass.
Frequently Asked Questions (FAQ)
Is this Bently Nevada 3500/60 module original and completely unused?
Yes. We supply exclusively Brand New Surplus units in original OEM anti-static packaging. These modules originate from verified surplus stock, feature zero backplane pin insertion marks, and undergo complete functional verification before shipment.
Why choose New Surplus over lower-cost refurbished temperature modules?
Refurbished temperature cards often contain degraded analog-to-digital converters and dried electrolytic capacitors due to continuous cabinet heat exposure. A failure in bearing temperature protection can result in unmonitored bearing destruction; spending 20% to 30% more for New Surplus guarantees OEM precision and reliable trip execution.
Can I mix RTDs and Thermocouples on the same 3500/60 module?
Yes. Each of the 6 channels on the 3500/60 is independently software-configurable. You can configure Channels 1–4 for 100 Ω Platinum RTDs (bearing temperatures) and Channels 5–6 for Type K Thermocouples (exhaust gas temperatures) on a single card.
How do I replace a faulty 3500/60 without stopping the turbine?
Open the 3500 Rack Configuration Software, navigate to the 3500/60 slot parameters, and enable Software Bypass for that slot. This prevents the monitor from firing system trip relays during physical removal and card installation.
Does replacing this card require downloading configuration data?
Yes. Hardware parameter settings are maintained in the 3500 System Monitor, but you must connect using 3500 Rack Configuration Software to verify sensor calibration curves, cold-junction compensation profiles, and alarm setpoint logic for the new card.
What warranty is included with this New Surplus temperature card?
Each New Surplus Bently Nevada 3500/60 module includes a full 1-year replacement warranty, a verified serial number tag, and a complete pre-shipment QC inspection report.
