Product Introduction (No Fluff)
This 163179-01 serves as a versatile 6-channel thermal protection module within a Bently Nevada 3500 rack, tracking discrete temperature points on critical machinery. It processes both RTD and thermocouple signals to trigger precise, programmable alarms before thermal damage occurs.
Sourcing this exact OEM replacement part prevents catastrophic machine failures when legacy temperature monitors drift or fail. Keeping verified new surplus stock on hand drastically reduces unplanned downtime during critical backplane failures or when expanding thermal monitoring coverage.
QA & Testing SOP (Dynamic & Transparent)
Temperature monitors demand precise calibration. Every 163179-01 undergoes an inbound anti-counterfeit inspection, verifying PCB silkscreen, component lot codes, and Bently Nevada factory labels. Next, the module is mounted on a dedicated 3500 test rack to validate backplane communication. We inject precision resistance and millivolt signals to verify the module accurately calculates temperature values and triggers Alert/Danger relays at the exact programmed setpoints. Finally, a 4-hour continuous burn-in under nominal load catches marginal A/D converters before they reach your panel. All units ship in dual-layer ESD shielding with a printed QA test report.
Installation Pitfalls & Guide (Engineer to Engineer)
❗ Sensor Type Configuration: This module is highly flexible but unforgiving if misconfigured. Each of the 6 channels must be explicitly programmed in the 3500 Configuration Software for the specific sensor type (RTD or Thermocouple). Connecting an RTD to a channel configured for a thermocouple will result in wildly inaccurate readings.
❗ Recorder Output Limitation: The 163179-01 (3500/60) does not provide 4-20mA recorder outputs. If your application requires analog trend recording to a DCS or chart recorder, you must use the 3500/61 variant instead. This module is strictly for digital alarm and relay logic.
❗ TMR Redundancy: For critical assets, this module supports Triple Modular Redundancy (TMR). If utilizing TMR, ensure you are installing three identical modules side-by-side and have configured the voting logic correctly in the software to maximize fault tolerance.
Replacement Protocol:
- Pre-Install: Lock out the 3500 rack power. Verify 0 VDC at the backplane. Ground yourself properly.
- Removal: Release the front panel retaining screws. Extract the failed module straight out. Inspect the backplane connector for bent pins.
- Install: Align the 163179-01 with the guides. Seat it firmly and secure the faceplate screws. Reconnect the RTD/Thermocouple field wiring.
- Power-on Test: Restore rack power. Use the 3500 Configuration Software to verify the module is recognized. Check the front panel OK LEDs and validate live temperature readings against a handheld calibrator.

Technical FAQ
Is this an exact drop-in replacement for my older 3500/60 module?
Yes, the 163179-01 maintains complete backward compatibility with existing 3500 racks and configurations. It offers the same 6-channel temperature monitoring and integrates seamlessly with the 3500 Configuration Software. You can swap it directly into an older slot without reconfiguring the entire rack.
Why is this listed as “New Surplus” instead of factory-new?
This is genuine Bently Nevada stock that was never deployed in a power plant or refinery. It has been stored in climate-controlled inventory rather than exposed to harsh industrial environments. You receive the exact same MTBF and lifespan as a factory-fresh unit, typically at a significantly lower cost and without the 16-week lead time.
Can I hot-swap this temperature monitor while the 3500 rack is live?
No. The 3500 backplane does not support hot-swapping the temperature monitor module. Removing it under power will cause an immediate loss of thermal monitoring for the connected channels, potentially disabling critical machinery protection. Always schedule this replacement during a planned outage or shutdown window.
What is the warranty coverage on this part?
We provide a standard 12-month functional warranty. If the module fails under normal operating conditions within that window, we replace it. Our QA testing proves the module processed temperature signals accurately before it left our bench, so we stand behind our inventory.
My 3500 system is aging. Should I replace this module or plan a full system migration?
If this is an isolated failure, replacing the 163179-01 is the most cost-effective way to keep your thermal protection system compliant with API 670. However, if you are experiencing cascading backplane communication errors or multiple monitor failures, your entire rack may be nearing end-of-life. Use this replacement as a bridge to schedule a comprehensive migration during your next major turnaround.
