Speed Monitor IK 9055 The speed monitors IK 9055, IL 9055, SK 9055 and SL 9055 monitors the rotational speed of motors. They recognise and monitor impulse signals of e. g. proximity sensors and protect machines and produced material or allows speed depending switching in production processes. Advantages . Protection of persons, machines and products . Easy setting . Universal input, for configuration of different sensors (PNP, NPN, 2-wire, contact, voltage) Features . According to IEC/EN 60255-1 . Detection of over- or underspeed or frequency, function selectable . 3 selectable ranges for frequency or speed, adjustable tripping value . Ranges up to 10 kHz ( 600.000 ipm) available,therefore suitable for turbines, centrifuges and similar applications . Adjustable hysteresis . Input also suitable for SKF sensor bearings . As option for Namur sensors . As option for permanent magnet sensors . As option with adjustable switching delay/start up delay . On request with manual reset .
