Product Core Brief
- Model: 170180‑01‑00
- Brand: BENTLY
- Series: FieldMonitor 1701 System
- Core Function: Provides two mixed‑signal input channels to connect proximity probes or accelerometers for rotating‑machinery condition monitoring.
- Product Type: External Transducer I/O Expansion Module
- Key Specs: 2 mixed‑type transducer channels | ‑24 VDC sensor excitation | Terminal‑base slot‑mount ⚠️ EOL — limited stock remaining
Product Introduction
BENTLY 170180‑01‑00 occupies one slot inside a FieldMonitor terminal base to add external transducer inputs. It supplies ‑24 VDC excitation for eddy‑current probes or seismic accelerometers.
Unlike fixed‑type monitor cards, this unit lets you mix probe and accelerometer inputs within one base. It maintains stable transducer drive current up to 37.6 mA at 25 °C —though your mileage may vary with long unshielded field cabling.

Quality Control Process (Engineer’s Perspective)
- Incoming Verification: Source traceability, serial number anti‑counterfeit check, visual inspection (no corrosion/scratches). Check edge connector pins for bending or wear.
- Live Functional Test: Power‑on self‑check, base comms handshake, continuous load run >24 hrs with temp logging. Capture LED status snapshots every two hours.
- Electrical Parameter Test: Insulation resistance (500 V Megger, >10 MΩ), ground continuity. Flag any resistance drift below threshold.
- Firmware Verification: Read/record firmware version, photograph DIP switch/jumper settings. Well, technically it supports channel‑by‑channel transducer type selection, but only on firmware v3.1+.
- Final QC & Packaging: Anti‑static bag seal, QC Passed label with date. Matching terminal hardware bagged alongside the unit.
Replacement Pitfall Guide
❗ Firmware Mismatch: The unit will lock mixed‑transducer configuration if host terminal‑base firmware falls below minimum revision. Older releases force identical sensor types across both channels.❗ DIP Switch / Jumper Misconfiguration: Factory defaults rarely match field settings. Pay close attention to channel input‑mode jumpers on the module edge connector.❗ Terminal / Cable Incompatibility: Pin definitions shift across hardware revisions. Cross‑reference wiring drawings before connecting proximity probe or accelerometer field cables.❗ Power Supply Mismatch: Recalculate total terminal‑base power with 20% headroom. Adding this module plus multiple transducers can push marginal 24 V DC supplies over their continuous rating.❗ ESD Damage: Use anti‑static mat; caution in dry environments. Static discharge can degrade transducer excitation circuitry with no visible physical damage.
Keep these in mind and you’ll cut 90% of rework time.
