It processes high-frequency pulses from speed sensors on rotating machinery such as turbines, compressors, and large electric motors. The module incorporates overspeed trip logic and dual output channels to trigger safety interlocks upon detecting excessive rotational speeds.\u003c\/p\u003e\n\u003ch3\u003eFrequency Input and Direction Detection\u003c\/h3\u003e\n\u003cp\u003eThe module accepts primary speed measurement inputs up to a maximum frequency of 50 kHz. A secondary speed input channel enables rotational direction detection by evaluating the phase relationship between dual pulse signals, providing comprehensive speed and directional feedback for diagnostics and control loops.\u003c\/p\u003e\n\u003ch3\u003eTrip Logic and Output Configurations\u003c\/h3\u003e\n\u003cp\u003eInternal overspeed trip logic evaluates measured pulse frequencies against configured limits.
