Working principle
1. Adopt foreign technology and good to replace imports.
2. The circuit can be switched on or off according to the preset number
3. Using large-scale application-specific integrated circuits, strong reliability
4. with power failure memory function
5. Retention and non-retention functions
6. Counting signal should be electrically isolated
Instructions for use
When counting mechanical switches, connect 3 and 5; when counting pulse signals, connect 5 plus 6 negative; when counting photoelectric switches, connect 3, 5, and 6.
Turn on the power after preset.
The counter has a memory function, that is, the number set after power-on is invalid.
If you need a new preset, please press the reset switch after the number is preset, or turn off the power for more than 0.5 seconds and then turn it on again.
It has the accumulative counting function when working in the holding function state, and has the function of automatic resetting when starting up when working in the non-maintaining state.
If the count bounces back, please connect 1uf-10uf capacitors at the meter port, 6 connect the negative terminal of the capacitor and 5 connect the positive terminal of the capacitor.
