First, an overview :HM200 is a small signal generator can produce a maximum 100KHz frequency and duty cycle adjustable pulse signal , can also produce steering control signal.The module is easy to use, the frequency of the data input by key operation , update now output frequency.

Second, product applications: signal generator ; instrument calibration ; DC motor control ;

Third, the technical parameters:No. Item Parameter Unit RemarkA pulse signal range of 1 ~ 100000 Hz is 1 to 99% duty cycle pulse signal2 pulse duty cycle range from 1 to 99% duty cycle3 5 VDC pulse signal amplitude maximum amplitude 5.0Vp ( constant output amplitude )4 servo signal frequency 100 Hz5 servo signal pulse width 500 ~ 2500 us6 7 ~ 12 VDC operating voltage7 working current <50 mA8 Operating temperature -40 ~ 65 Celsius9 Storage temperature -40 ~ 65 Celsius10 Size 57 * 45 * 20 mm Length X Width X Height
