2. Functional Features

Keyphasor Signal Provision: It is a half-height, dual-channel module designed to provide keyphasor signals to the monitor modules within the 3500 frame. It receives input signals from proximity probes or magnetic pickups and converts these signals into digital keyphasor signals, which indicate when the keyphasor mark on the shaft aligns with the keyphasor sensor.
Multi-signal Support: Under normal configuration, the 3500 machinery protection system can accept a maximum of four keyphasor signals; under paired configuration, it can accept up to eight keyphasor signals. Keyphasor signals are event pulses generated once or multiple times per revolution from a rotating shaft or gear. They are used to provide precise timing measurements, enabling the 3500 monitor modules and external diagnostic equipment to measure shaft speed and vector parameters such as 1X vibration amplitude and phase.
Enhanced Signal Processing Capability: This module is an improved version for the 3500 system. Compared with previous designs, it offers expanded keyphasor signal processing capabilities while maintaining full backward compatibility in terms of form, fit, and function with the keyphasor modules in existing systems.
