Description
Product Introduction
The Bently Nevada 170110-01 is a four-channel rear Input/Output (I/O) interface module designed specifically to pair with the 3500/42M Proximitor/Seismic Monitor inside the 3500 Machinery Protection System. Installed in the full-height rear slot directly behind the primary 3500/42M processing card, the 170110-01 facilitates field wiring connection in high-density cabinet layouts.
Engineered for External Termination configurations, the 170110-01 replaces direct onboard screw terminals with a heavy-duty multi-pin connector interface. This allows pre-fabricated multi-conductor cables to route transducer signals and -24V DC sensor power between the 3500 rack and remote DIN-rail terminal blocks or marshalling cabinets, reducing wiring congestion inside the main rack enclosure.

Application Scenarios & The “Trench” Experience
In large-scale petrochemical facilities or power plants with high point counts, landing hundreds of individual sensor wires directly onto the back of a crowded 3500 rack causes severe wire management issues and slows down maintenance. Racks using the 170110-01 External Termination card route field cables to a separate marshalling cabinet with organized DIN-rail terminal strips. During a module replacement, technicians simply unclip the multi-pin multi-conductor cable harness from the 170110-01 card faceplate, swap the module, and reattach the harness—reducing loop outage time from hours to minutes while keeping field wiring untouched.
- High-Density Control Rooms & Marshalling Cabinets: Cleanly separates rack backplane processing from field wiring marshalling strips.
- Refinery & LNG Processing Trains: Allows field wiring to be terminated and tested at remote terminal blocks before installing 3500 racks.
- Power Plant Retrofits: Ideal for installations utilizing multi-pin trunk cables to simplify inter-cabinet wiring runs.
- 3500 System Spares & Maintenance: Essential replacement rear card for systems utilizing external multi-pin cable harnesses for 3500/42M monitor channels.

Transparency SOP: Quality Assurance & Testing
- Visual & Structural Inspection: Multi-pin connector headers, internal PCB traces, gold-plated contacts, and latching hardware are thoroughly inspected for bent pins, physical wear, or corrosion.
- Backplane & Chassis Fit Test: Inserted into a live Bently Nevada 3500 test rack behind a functional 3500/42M main card to verify mechanical seating and backplane pin engagement.
- Multi-Pin Harness & Signal Continuity Audit:
- Cable Connector Engagement: Checked latching stability with standard Bently Nevada multi-pin external termination cables.
- 4-Channel Signal Routing: Precision dynamic signals and -24V DC transducer power are passed through all 4 channels to verify linear voltage transmission to the front 3500/42M card.
- Final ESD Packaging: Cleaned, fitted with protective connector dust caps, sealed in anti-static shielding bags, and packaged in heavy-duty foam containers.
The Veteran’s Tech Trap Guide (Crucial Value-Add)
- ⚠️ Internal vs. External Termination Mismatch: The 170110-01 requires a multi-pin cable harness running to external termination blocks. If your setup routes field cables directly into the back of the rack with screw terminals, you need an Internal Termination module (such as the 135489-01 or 161216-01) instead.
- ❗ Cable Harness Strain Relief: Ensure external multi-pin cable harnesses have adequate strain relief attached to the cabinet rack frame. Hanging heavy multi-conductor cables directly off the 170110-01 multi-pin connector can strain internal PCB solder joints over time.
- ⚠️ Front Monitor Card Pairing: Pair this module strictly with a 3500/42M Proximitor/Seismic Monitor. Attempting to pair the 170110-01 with incompatible modules (e.g., 3500/25 Keyphasor or 3500/45 Position monitors) will cause a slot configuration fault on the 3500/22M RIM.
- ❗ External Terminal Block Compatibility: When replacing or configuring external termination systems, verify that the external DIN-rail terminal block model (e.g., 125808-01 series) matches the transducer power and shield requirements configured on the 3500/42M front card.
Frequently Asked Questions (FAQ)
Q: What is the main function of the Bently Nevada 170110-01?
A: It is an external termination rear I/O card for the 3500/42M Proximitor/Seismic Monitor, using multi-pin connectors to connect 4 transducer channels to remote DIN-rail terminal blocks via multi-conductor cable assemblies.
Q: Can field wires be screwed directly onto the 170110-01 module?
A: No. The 170110-01 features multi-pin cable headers rather than screw terminals. Direct screw termination requires internal termination cards like the 135489-01 or 161216-01.
Q: What transducer types are supported through the 170110-01 interface?
A: It supports inputs from standard 3300 XL proximity probes, accelerometers, Velomitors, and electrodynamic Seismoprobes as configured on the front 3500/42M card.
Q: Is it necessary to power down the 3500 rack slot before replacing this module?
A: Yes. Powering down the specific rack slot or isolating transducer power before disconnecting or replacing rear I/O cards prevents unwanted arcs or transient spikes across backplane pins.
Q: What warranty is provided on surplus or reconditioned 170110-01 modules?
A: All New Surplus and fully reconditioned Bently Nevada 170110-01 modules include a full 12-month replacement warranty from the invoice date.
