using KC868-A16 ESP32 relays at 220v - poseido - 09-27-2024
Hello
I've ben trying to make my home heating instalation work with first some esp32+tasmota+DIY board, then integrated borads with ESP32 and realys.,.. but now I found Kincony products and they do look great! I want to use them!
My issue is the following:
I want to control my water based heating floor circuits with the KC868-A16 ESP32, each circuit has a valve that works with 2 wires, at 220v-230v, if there is current, they open, if not they selfclose (similar to this: Actuador térmico eléctrico, radiador para calefacción por suelo radiante, válvula NC, N58A, 230V - AliExpress 13) but they work with 220 volts, so seeing the KC868-A16 ESP32 capabilities, I see that the relay outputs say 0-12v to 24v...
any work around for that? using 220v with a very low amperage would kill the PCB?
thanks!

you can chose a DC12v or 24v valve, control by KC868-A16 output terminal directly.
another way , add a KC868-E16v2 extend relay module, so that you can use any work voltage of valve.
