SS95: Speed Sensing Relay

- Magnetic pick-up input

- 3 Speed set point

- Output relay contact

 

            Speed Sensing Relay SS95 provides 3 user adjustable trip levels with LED relay state indication and a speed indicator output signal. Trip functions provided are

            CRANK disengages the crank starter

            UNDER SPEED energises protection or underspeed alarm

            OVER SPEED alarms or trips on overspeed

            A magnetic pick-up, situated close to the engine flywheel, produces a high frequency pulse train directly proportional to the number of teeth passing it. The frequency of these pulse is converted to an analogue signal which is used to provide both engine speed indication and the signal to the trip circuitry.
