Hi all,
I've started a project to create an 12-24V compatible Arduino, to use it with more industrial sensors and actuators. In this, I'll work towards a V1 with some basic protection but may add more in the future.
I have an optocoupler (4N25), but I'm struggling to interpret the datasheet (https://www.vishay.com/docs/83725/4n25.pdf)
So far I've got the following:
Maximum input voltage: ? (Like with an LED, forward voltage 1.3-1.5V)
Maximum input voltage (reversed): 5V
Maximum input current: 60mA / 100mW (3A for <10us)
Maximum output voltage: 70V
Maximum output current 50mA (100mA < 1ms) / 150mw
In this; I'm not quite sure about two things:
1. What is the "Emitter base breakdown voltage", I'm guessing that if you mix up the polarity on the output of the output (specifically between emitter and base) up to 7V, it'll break
2. Could I input 24V to this unit w/o breaking it? Is really only the current a limitation on the input?
