4 Channel 16 Amp Relay Module with WiFi(WIFI484)

The "WIFI484" allows you to control 4, 16-Amp relays over an Wifi connection using a built in web page or via simple TCP/IP based commands. An additional 4 analoge and 8 digital IO pins allow connection of other devices. Screw terminals on normally open, normally closed and common relay pins allow for easy connection.

Our Code: MCU-60152


The 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 available on the screw terminals. 
Digital inputs are able to be configured to remotely control outputs on all of our new ethernet relay boards (both wired and WIFI), the older ETH-RLY02 and ETH-RLY16 are not compatible however. This offers the opportunity to construct a system where an input can control an output anywhere on the earth provided both locations are connected to the network/internet.
