I need to trip a
12V output with a signal. In other words, I will send a signal through the output of my
microcontroller and this signal will activate its output.
I've figured out several ways to do this, the most common ones being activation with relay or activation with Mosfet. As in the examples below.
My concern is reliability, I need to make sure that the output is triggered. How many drives per day will be needed to ensure that the system supports a large number of activations?
How can I know which of the forms of activation is the most reliable? Which one will guarantee the activation of the output without fail and which supports the largest number of activations?
EDIT- The load connected to "output12v" is an electronic lock that consumes around 1A.
