AVT447 B

Stopwatch system equipped with typical LED displays and control systems. The device can also work with large-size displays.

Basic parameters:

• The stopwatch allows you to measure time in the range from 0.01s to 99mins and 99.99s with an accuracy of 0.01s.
• The stopwatch can be triggered by a system that receives the bang of the shot from the starting pistol. This, of course, does not exclude the possibility of manually activating the stopwatch by means of a button.
• The stopwatch can be stopped by a signal from an infrared photocell. The intersection of the light beam (in the infrared), eg by the first at the finish line, immediately stops the countdown. Also in this case it is possible to stop the stopwatch manually.
• Resetting the system can be done manually using the button. The results are presented on a six-digit LED display. Special connectors enable the connection of seven-segment displays with very large (20 cm high) dimensions.
• The stopwatch system can be powered from any DC voltage source with a value of 7..16Vdc, not necessarily stabilized. However, the use of large displays requires the inclusion of a separate power supply with a voltage of min. 24Vdc and current efficiency approx. 1.5A.
• Power supply 7 ... 16Vdc.
• Dimensions of the assembled module: 55 x 130 x 30 mm
• The set includes a printed circuit board, a set of elements and documentation
