Introduction ED4000(SM4) Speed Monitor is a totally new rotational speed monitoring equipment; it uses the principle of photo detector and microprocessor to
accurately calculate a wide range of rotational speed. It detects rang 1~999rpm and the rotational speed display on 7-seg led.
There is a contact relay that could be used either for alarm or control purposes during the monitoring process. The alarm set point could be directly set by numerical knobs which is more convenient and more accurate than conventional means. It comes equipped with analog signal output which could be utilized for various display indications and more
precise control. Other features include anti-reversal action, which could prevent the wrong power supply connection after maintenance of the
motor. It is ideal for applications in monitoring low speed, stop and overload situations..
Features Maximum monitoring range 1~999rpm. 7-seg led display 0~999 Alarm monitoring: low speed, stop, reverse, blackout and overload. Start up delay function allow motor to run up gradually. Alarm delay function can avoid fault alarm which many caused by temporary slow down or load changed. Selectable rotate direction for both CCW and CW makes installation more versatile. Light pulses are not affected by environmental conditions. Complementary to FineTek PB/PM series digital Panel meter to indicate speed.
