Bently Nevada 3500/40M 176449-01 Four-Channel Proximitor Monitor Module
A current four-channel 3500 rack monitor for proximity-transducer vibration and position measurements.
Product Identification
3500/40M 176449-01 is the current main 3500/40M Proximitor Monitor module. Its four channels accept compatible Bently Nevada proximity-transducer signals, condition them and compare measured values with programmed alarm setpoints.
The monitor can process radial vibration, thrust position, differential expansion, eccentricity or REBAM functions. Channels are configured in pairs, allowing up to two measurement functions on one module.

Functions
- Conditions four compatible proximity-transducer signals for machinery-protection measurements.
- Compares each configured channel with programmable alarm setpoints.
- Supports radial vibration, thrust position, differential expansion, eccentricity and REBAM functions.
- Configures channels in two pairs so one module can run up to two measurement functions.
- Provides one buffered coaxial transducer output per channel for local diagnostics.
Applications
- Radial vibration monitoring on rotating machinery with proximity transducers.
- Thrust-position and shaft-position protection within a 3500 rack.
- Differential-expansion or eccentricity channels configured in supported pairs.
- REBAM channels where the required monitor firmware and rack software are installed.
- Machinery-protection retrofits that retain the documented 3500/40M channel strategy.
Lifecycle
- Use the complete 3500/40M 176449-01 designation when ordering the current main monitor.
- Match the rear I/O type: internal termination, external termination or internal barrier.
- Back up the rack configuration and document both channel-pair functions before exchange.
- Confirm rack configuration software, data-interface module firmware and configuration-module firmware compatibility.
- Verify alarm setpoints, channel values and voting logic after commissioning.
