I'm thinking of using either KC868-A16S or KC868-A8S to control 24V lights/devices in a campervan via ESP32 with momentary switches and via a smartphone. Both boards indicate they handle AC current. Can they also handle DC 12v and/or 24v loads with the built in relays? If so, what is the max amps per relay and in total? What is the make/model/part number of the relay switch used on the board?
They also indicate they use DC 12V to power the board. Can they use 24V power as well?
