AnIn used as 24vdc DigIn

(1/2) > >>

Lukey:
I'm trying to use the smallest size possible controller, therefor id like to use a 5v AnIn pin as a DigIn with 24vdc input. from the switch

Is it as simple as using a resistor to drop the 24vdc down to 5vdc?

Anyone done this before and can advise what size resistor they use?

*EDIT FYI, I do not want to use the 5+ from the controller or use a relay to switch the 5+.
The application requires it to be compact and simple.

acmall:
Which controller are you using? Which input pin?

It would be worth checking the ratings for the input you are using as there is a good possibility it will be rated to more the 24V. This can be found in the Controller Family Technical Information document for the controller family you are using.

11130915 / MC012-110, pin 5

This is the document for the MC0xx-1xx family

For some reason the input and output specifications are in a section with the heading CAN.

Lukey:
Thank you acmall.

Yes odd that the heading is CAN

There is mention Middle range and High range, nothing about Low range.

I have only seen the range selection on the multifunction inputs, so I'm not sure about this information.

Overall it does mention max of 36v  ???

I'm not convinced.
