WIFI484 4 x 16A WIFI relay liquid-level use thick wires soldered directlyThe WIFI484 provides four volt free contact relay outputs with a current rating of up to 16Amp each, 8 digital I O and 4 analogue inputs. The module is powered from a 12vdc supply which can be regulated or unregulated. The DC input jack is 2. 1mm with positive core polarity, DC supplies are required to supply at least 500mA at 12vdc. The relays are SPCO (Single Pole Change Over) types. The normally open, normally closed and common pins are all
