Hello. Can I use digital input for 24v AC signals? I want to receive signals from google nest thermostat. ![[Image: 3fh4wm4]](https://ibb.co/3fh4wm4)
On the datasheet I see an optocoupler with two diodes. Does it mean that it can be used for alternating current? But it is signed as EL357. In the datasheet for the EL357 I see one diode. ![[Image: QvqT8JW]](https://ibb.co/QvqT8JW)
And can be used for DC-DC conversion. Can you help me figure it out? Thank you in advance.
