can you expand onHow to connect 110V DC to the GPIO of the Microcontroller with all EMI-EMC Protection.
Please explain with the circuit schematic ASAP...
Can you draw the circuit??Use a SSR (Solid State Relay) !
Thanks for the explanationDo a search for Solid State relay, many examples out there.
You can get different input volage and various output types, AC DC etc.
You can roll your own, or :--
An example of the internals of an off the shelf (AC) version.

If all you want to do is connect 110 VDC to a GPIO of a uC just use an optocoupler. You fail to mention what GPIO voltage you want? Could be 3.3 volts or 5.0 volts? A simple Google of GPIO optocoupler interface will bring up a dozen examples. Additionally adding ASAP is not going to make people jump. Please works much better. You can also explain better your objective. Do you want to use a GPIO to turn On/Off 110 VDC or use a GPIO to detect the presence of 110 VDC.How to connect 110V DC to the GPIO of the Microcontroller with all EMI-EMC Protection.
Please explain with the circuit schematic ASAP...
