hello to all
i have a optoisolator tlp614-4 but i don't know how connect with transistor with 12V
i have problem at exit of optoisolator
can i have an example please?
sorry for enligsh
thank you
sorry tlp624-4
The output is like a transistor, it can carry perhaps 10mA or so. You can use it
as a high side switch or a low-side switch as you like.
It depends on what you are connecting and what you're trying to do, but one way would be as a [u]Darlington Pair[/u].
i want to connect this array transistor uln2803 is of vellman board 16 relay
can i have an example
please
thank you
i have try but not run
next the optoisolator i have a pin is + and another is -
i want to control 16 relay with 16 optoisolator with 12V
thank you
Then you use the opto isolator output as a high side switch. Collector to 5V, emitter via 1k resistor
to ULN2803 input. (Or if the relay board is 12V, use the 12V rail for the collector).
yes but i don't know how to connect optoisolator to transistor
i remember than i use tlp624-4
thank you
