Can i use IO.0 as interrupt input with 5V signal?

Hi,

I'm using the PLC ARBBOX PLC 20 I/O/s relay HF.

Can i use 5V input signal as interrupt input?


If it is possible, should i tune ON/OFF the DIP Switch for SDL/IO.0 ?

Thanks in advance.

Hi, 

Yes, you could use the I0.0 input as interrupt and it is necessary to switch the DIP ON abling the I0.0 configuration instead of SDL.

On the other hand you could also connect the 5Vdc signal directly at the SDL pin available on the Ardbox Relay PLC which is the same you could connect on The Arduino Leonardo board. (Important: if you use SDL pin you can not connect a higher voltage than 5Vdc).

See an example of use at the technical features link:
