using KC868-A16 ESP32 relays at 220v

[poseido]

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.
