It is engineered to monitor shaft rotative speed, rotor acceleration, and rotor direction by processing inputs from proximity probes or magnetic pickups. The module compares these inputs against user-programmable alarm setpoints to provide critical machinery protection and predictive maintenance data.\u003c\/p\u003e\n\u003cp\u003eThe 3500\/50M can be configured to supply conditioned Keyphasor signals to the 3500 rack backplane, eliminating the need for a separate Keyphasor module in many configurations.
