Coin acceptor COM11719/ Monedero electronico COM11719

Hi everyone Im working on an Arduino proyect using the COM11719 coin acceptor and I have some questions, the datasheet ( https://cdn.sparkfun.com/datasheets/Components/General/3.jpg ) says that it works with 12 V , and 50mA, the outpout has to be then 12V and 50mA, obviusly I know I have to use a voltaje-divisor to introduce the signal to any pin of arduino, but my question is: I have a 12V 1000mA charger, could I burn my coin acceptor if I try to supply energy with it? how can I build a current divisor for it ?

Thanks for reading!

Hola a todos estoy trabajando en un proyecto de Arduino y estoy usando el monedero electronico COM11718, y tengo algunas dudas, la hoja de datos( https://cdn.sparkfun.com/datasheets/Components/General/3.jpg ) dice que trabaja con 12 V y 50 mA , por lo tanto la salida tambien es de 12 V y 50 mA, obviamente se que debo de usar un divisor the voltaje para introducir la señal a cualquier pin de Arduino, pero mi pregunta es: tengo un eliminador de corriente(cargador) que me da 12V y 1000 mA, puedo llegar a quemar mi monedero electronico si trato de conectarlo ahi? Si sí, cmo puedo hacer un divisor de corriente?

Gracias por leer!

You can use any 12V DC supply with the coin acceptor. Make sure that your charger delivers 12V, not much more or less, if not used to charge a battery.

If the acceptor output is "open collector", you can connect it directly to a digital input, with a (1k) pullup resistor to the Arduino operating voltage (3.3 or 5V). Else your voltage divider approach will work as well.
