BENTLY NEVADA 3500/25 125800-01 Keyphasor I/O Module (Internal Terminations)

Description

BENTLY NEVADA 3500/25 125800-01 Keyphasor I/O Module (Internal Terminations) is a semi-high, dual-channel component integrated into the 3500 series machinery protection system, as part of the enhanced 3500/25 Keyphasor module lineup. It is designed to receive input signals from magnetic sensors or proximity probes when a keyphasor mark on a rotating shaft aligns with the sensor, then convert these analog inputs into digital keyphasor signals for transmission to monitor modules in the 3500 rack.

This module supports flexible system configuration: in standard setups, the 3500 machinery protection system can accept up to four keyphasor signals, while paired configurations (installed in consecutive half-slot positions) allow for up to eight signals. Its core functions include enabling precise timing identification using pulses from rotating shafts or gears, which allows 3500 monitor modules and external diagnostic tools to measure critical shaft parameters such as rotational speed, 1X vibration amplitude, and phase.

Key technical specifications include dimensions of 24.2 cm x 11.2 cm x 2.5 cm and a weight of 0.38 kg. It offers high precision, stable performance under various operating conditions, and full backward compatibility with existing Keyphasor modules for seamless integration into legacy systems. Ideal for condition monitoring of rotating machinery, it is widely applied in steam turbines, generators, compressors, pumps, and wind turbines.
