12V on Power, 24V on DIN input

[spittet]

Hi,

On any programmable controller in the Danfoss family, is it OK if we power the controller by a 12V source but the a DIN input pin is connected to a switch that can toggle between GND and 24V source?

Have a good day!

Hi Spittet!

For the PLUS+1 MC0XX-1XX Controller Family, as can be read in Technical Information L1321895 BC00000227en-US0301 on page 8, a digital input DIN has a Input voltage
range 0-36V.

Also the PLUS+1 SC Controller Family, as can be read in Technical Information L1206334 BC00000205en-US0701 on page 11, a digital input DIN has an allowed voltage at pin 0-36V.

This means for the controllers mentioned above there shouldn't be any issue if you connect your controller as in your text.

I hope this helps!

Best regards
