Miscellaneous › Others › interface 24v to microcontroller
in my project I have to interface more than ten 24v line to microcontroller as inputs.. how can I do this.. for time being I am using 7805 .. is there any multi-input multi-otput voltage regaluator which takes 24v input and provide 4-5v output..
as I searched I got information about IC mc1489 with 4 IO.. but this is rs232 to ttl convertor..
please suggest me how to do this
thanks in advance
what you want to do actually?
do u want to sense analog DC voltage? like 0-24V?
if its so then its very simple.
u can use voltage divider and ADC.
select any ADC that has input analog input range of 0-10 V or 0 – 12 V
using voltage divider convert your 24 V in to analog input range of ADC
thats all
now you will get digital equivlent output of your 0 – 24 V input
i want to connect 24v signal to a single input lines of microcontroller..
there are around 30 lines with voltage level at 24v..
Hi,
You can use relay for this purpose..
Which controller you are using ?
Relay will solve your question…
i want to connect output of 24v dc relays as input to microcontroller
i am using atmega2560
simple .. use optocoupler ic ( *as per it datasheet) with it for signal to MCU.
