Product Details:

The BENTLY NEVADA 125800-01 Keyphasor I/O Module with internal terminations is the core signal processing board for the Bently Nevada 3500/25 enhanced Keyphasor module in the 3500 machinery protection rack system. This phase reference board receives pulse signals from proximity probes or magnetic pickups mounted on rotating shafts, converting raw sensor pulses into stable once-per-turn timing reference signals. The internal termination module integrates built-in signal terminal design, which simplifies field wiring work and eliminates the requirement for separate external termination blocks. It features two independent input channels that can be configured separately to collect phase and speed signals from one or two rotating shafts. The precise Keyphasor timing signal enables other monitor modules inside the rack to calculate rotating speed, vibration phase angle, 1X vector amplitude and orbit plots for rotating machinery. It supports hot swapping during rack operation without interrupting the normal machinery protection loop. Continuous self-diagnosis function monitors sensor wiring break, short circuit and module hardware faults, and reports fault status via LED indicators. It maintains stable signal output even under strong electromagnetic interference in industrial cabinet environments. It is widely used on steam turbines, centrifugal compressors, generators and other high-value rotating equipment in petrochemical, power generation and metallurgy industries, providing reliable phase reference data for vibration fault diagnosis and machinery protection.
