Model Number : JDM9-4 JDM9-6Type : 6-digit CountersDIY Supplies : ELECTRICALBrand Name : CKCTINNER : Mainland China
counter if sensor counting is used, Sensor (photoelectric switch or proximity switch) with the model specifications for PNP, DC 6V ~ 36V.Please contact customer service if you need a switchModel: JDM9-4 / JDM9-6Counting digits: 4 digits / 6 digitsCounting range: 1~9999 1~999999Preset method: dial switchCounting method: add/subtract countingCounting signal: contact signal/pulse voltage signal (sensor)Counting speed: 30 times/second 30CPSContact capacity: AC220V 5A (resistive load)Mechanical life: 1 × 10 ?Rated voltage: DC24V, AC220V, AC380VOverall dimensions: 78 × 78× 126mmOpening size: 71 × 71mmInstructions for use:The allowable fluctuation range of power supply voltage of 7.1 counter is 85% ~ 110% of the rated value, and the peak ripple coefficient of DC voltage is not more than 5%.If the count signal is input, the device with good contact reliability should be selected; the width of the pulse voltage signal should be greater than or equal to 10ms. Duty ratio 1: 1, voltage range 5V ~ 30V. The counter should be turned on or " reset " 50ms after the input count signal, otherwise the count may be unstable, The duration of the external reset signal should be greater than 50 ms.In the counting process, should not toggle the counter finger wheel switch, if you want to reset the number, you should first reset the counter.Counter Counting Signal and Reset Signal Input Connection Line should use double shield line, The shielding layer should be grounded at the signal input near the counter, and the connecting wire should not be too . Counter should avoid sharing a power cord with motor, electromagnet and other large inductive load.counter if sensor counting is used, Sensor (photoelectric switch or proximity switch) with the model specifications for PNP, DC 6V ~ 36V.
