Product Introduction (No Fluff)
This 1701/05 acts as the critical physical and electrical foundation within a Bently Nevada FieldMonitor system, providing the terminal connections and backplane routing for vibration and position monitor modules. It ensures reliable signal routing between field sensors and the processing monitors.
Sourcing this exact OEM replacement part prevents extended downtime when terminal bases suffer from physical damage, pin degradation, or corrosion. Keeping verified new surplus stock on hand allows maintenance teams to bypass lead times and restore machinery protection immediately.
QA & Testing SOP (Dynamic & Transparent)
Terminal bases demand absolute mechanical and electrical integrity. Every 1701/05 undergoes an inbound anti-counterfeit inspection, verifying PCB silkscreen, terminal block quality, and Bently Nevada factory labels. Next, we perform a comprehensive continuity test across all I/O pins to the front panel connector to ensure no open circuits or internal trace breaks. We also verify the mechanical alignment of the module guides. Finally, a visual inspection ensures no cracked solder joints or damaged terminal screws. All units ship in anti-static shielding with a printed QA test report.

Installation Pitfalls & Guide (Engineer to Engineer)
❗ Terminal Torque Specifications: Field wiring must be torqued to the manufacturer’s exact specification. Over-torquing can strip the terminal block threads or crack the PCB, while under-torquing leads to high-resistance connections, arcing, and eventual thermal failure. Always use a calibrated torque screwdriver.
❗ Shield Grounding Practices: The 1701/05 provides specific grounding points for sensor shields. Grounding shields at the terminal base rather than at the sensor bracket prevents ground loops. Verify your wiring diagram to ensure shields are terminated correctly at this base.
❗ Module Alignment: The 1701/05 features precision guide rails for the front monitor modules. Never force a monitor module onto the base. If it requires excessive pressure, inspect the base guides and backplane pins for damage or misalignment.
Replacement Protocol:
- Pre-Install: Lock out the FieldMonitor rack power. Verify 0 VDC at the backplane. Ground yourself properly.
- Removal: Disconnect all field wiring. Unscrew the failed 1701/05 from the rack rails. Inspect the backplane connector for bent pins.
- Install: Align the new 1701/05 with the rack guides. Secure to the rails with even torque. Visually inspect the mating surface one last time.
- Power-on Test: Mate the FieldMonitor front module. Restore rack power. Verify the “OK” LED and check for zero fault codes in the Configuration Software before reconnecting field probes.
Technical FAQ
Is this an exact drop-in replacement for my damaged 1701/05?
Yes, the 1701/05 is the standard terminal base for FieldMonitor systems. It is mechanically and electrically identical to the original. You can swap it directly, provided you verify the pin condition before mating the front module.
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 terminal base while the rack is live?
No. This is a structural wiring component, not a hot-swappable module. Removing it requires disconnecting all field wiring and unbolting the base from the rack. This will cause an immediate loss of monitoring for that slot. Always schedule this during a shutdown.
What is the warranty coverage on this part?
We provide a standard 12-month functional warranty. If the terminal base shows open circuits, mechanical defects, or pin damage under normal operating conditions within that window, we replace it. Our QA testing proves the assembly passed continuity tests before it left our bench.
My FieldMonitor module is failing. Do I need to replace the 1701/05 base too?
Not necessarily. If the failure was caused by a field wiring short, a lightning strike, or physical damage to the rear connector, the front module might be fine. Test the front module on a known good base first. If it passes, you only need the 1701/05. If the front module is also dead, replace both to avoid cross-contamination.
