Kinkony A24. Digital input - Wild_tatar - 01-23-2024 Hello. Can I use digital input for 24v AC signals? I want to receive signals from google nest thermostat. 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. And can be used for DC-DC conversion. Can you help me figure it out? Thank you in advance. RE: Kinkony A24.
