The 3500/42M 176449-02 is a 3500 series four-channel vibration/position monitoring module manufactured by Bently Nevada. It is an industrial-grade, high-performance module primarily used to monitor the vibration and shaft displacement of rotating machinery, issuing alarms or control actions when the signal exceeds a set threshold.
Independent Four-Channel Processing
Continuous "OK" Circuit Monitoring
Provides coaxial connectors for unconditioned, raw dynamic signal output
The 3500/42M Proximitor Seismic Monitor is a four-channel monitor that accepts input from proximity and seismic transducers. It conditions the signal to provide vibration and position measurements and compares the conditioned signals with user-programmable alarms.Each channel, depending on configuration, typically conditions its input signal to generate various parameters called static values. You can configure alert setpoints for each active static value and danger setpoints for any two of the active static values.

When using the 3500/42M 176449-02 monitor module, ensure it perfectly matches the rear I/O module type and that transducer types and alarm setpoints are accurately configured in the software. As the module is hot-swappable, verify proper rack grounding during replacement to prevent ESD damage. Additionally, periodically calibrate raw signals via the front-panel buffered outputs to ensure monitoring data aligns with actual machinery conditions, preventing false trips or missed alarms.
