V Coin Operated Timer Control Box& Programmable Control Coin Acceptor Electronic Device Multi Coin Selector Timer for Vending Switch Style, Metal. Output: Single Power Switch Output. Timer-EUC. Metal Box, Cash Box, EU1 Multi-Coin Coin acceptor, Coin Meter, WFC Timer Control Board, Power. The coin control timer is used to control the time of your electronic device. You can insert coins and decide the time that you would like your equipment to run. The.
Besides that, the DS has a programmable clock output that provides a square wave obtained by the clock frequency of the clock which is in turn determined by the 32, kHz quartz connected to pins 1 and 2 which, through a dedicated internal divider, can be reduced to 1 Hz, kHz, kHz it can also provide the whole clock. As with all the latest microcontrollers by Microchip, this can work between 1,8 and 3. For what concerns the bidirectional line, the functioning of this translator is like this: when SDA is at high level 5 V thanks to the pull-up resistor R2, the Q1 MOSFET is in interdiction and R1 resistor keeps pin 19 of the microcontroller at 3. In order to connect it, you will not use the 5-terminal connector, therefore you can disconnect that connector from the coin-operated box. Count down timer can be set for on time selected and counts down to automatically stop, or delete by pushing red button to left of display. The board we have combined with the coin-operated device you can see to two units connected in Fig.
