Processing phase-reference and speed signals for machinery diagnostic systems, the Bently Nevada 3500/25-01-02-CN serves as a high-precision, half-height module within the 3500 monitoring platform. This system component conditions pulses from proximity probes or magnetic pickups to determine rotational speed and once-per-turn phase angles, delivering critical reference data directly to the backplane for transient and steady-state machinery analysis. Configured as a single half-height card supporting two channels and paired with an external termination I/O module, this unit integrates seamlessly with local regional standards via its country-specific CN approval path.

The Enhanced Keyphasor Module replaces older legacy keyphasor units within standard 3500 racks. It is critical to note that while this enhanced card is backwards compatible with standard backplanes, half-height card pairings must match. You cannot pair an older non-enhanced module in the same vertical slot allocation as an enhanced module.
When utilizing option 02 (External Terminations), ensure that the cable length between the external termination block and the rear I/O module does not exceed specified noise margins. High-frequency ambient EMF from neighboring variable speed drives (VSD) can inject signal noise, resulting in false once-per-turn double-triggering or missed pulses.
During rack commissioning, configure the threshold voltage and hysteresis parameters within the 3500 Rack Configuration Software to match the specific transducer bias. For a standard 8mm Proximitor, target a trigger threshold that falls precisely in the middle of the physical notch or projection voltage swing to prevent signal dropout during thermal shaft expansion.
