This is a three-digit 0.56 inch high-bright red digital tube counter with a plastic case head. It can be used for counting. The counting rule is that there is a button. Every time you press it, the number will increase by 1, and the maximum count is 999.    The display window size is 4*2 cm. The power supply is DC 5V. I will draw out the power supply and button wiring, and I can connect the related power supply or button controller. 

  Function can be selected (what function is needed, negotiate in advance)): 

 1. Counter. 

 2. Stopwatch (99.9 seconds mode, 999 seconds mode, 9.59 minutes) 

  3. Thermometer (22.5 degrees, three digits) 

 4. Display number (123, off) 

 The control method of the counter: There is a plus 1 key, a minus 1 key, and a clear key. 

The count is not saved by default and will be cleared after power failure. If you need to save data, you must make an appointment in advance and make a special order. 

 Pulse counting is also possible, but the customized program should be reserved in advance. The default is normal counting. 

In addition, the control method can also be customized according to your own requirements, such as adding 1 for relay control, adding 1 for photoelectric switch control, adding 1 for contact switch and so on. I only provide display counters, other photoelectric switches, contact switches, etc., which need to be matched by myself. If I need to support them, please send them. After I debug them, I will send them together. If it is a standard device, there is no need to debug, just take a picture of the counting screen. It's okay. These need to be agreed online in advance, remember! ! !
