With this timer module you can build simple vending machines easily. Just plug your coin acceptor pulse output into the coin input on the board. Then you can program the price (or pulses) required to toggle the relay on by simply pressing the buttons on board. Also you can program the time that the relay would be enabled. All configurations are stored on the EEPROM, so they will remain even after the power goes off.
This board works at 12V DC and accepts pulses from an open collector coin acceptor. Every pulse is equal to one credit. Of course you can use any other circuit or button to send the pulse, but keep in mind that it should be digital and already debounced to avoid false triggering.
It is specifically designed for creating vending machines, you can use it to sell electricity, turn on pumps for dispensing products or activate mechanisms that dispatch something or allows people access to restricted payment areas.
Is a compact module that is trusty and can work for long periods of time, also you can customize it with your own firmware that fits your application. This module is based on the PIC12F1822 and you can find all the design files on Github.
