8 Channel 16 Amp Relay Module with Ethernet (ETH-RLY16)

The "ETH-RLY16" allows you to control eight 16 Amp relays over an Ethernet connection using a built in web page or via simple TCP/IP based commands. Screw terminals on normally open, normally closed and common relay pins allow for easy connection.

Our Code: MCU-60093


The ETH-RLY16 provides eight volt free contact relay outputs with a current rating of up to 16Amp each. The module is power 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.


  • Operating Temperature: -40C to +70C
  • Number of Relay's - 8
  • Power - 12V DC adaptor, supplied separately.
  • Control interface - HTTP (webpage) or TCP/IP over Ethernet.
  • Relay current - Up to 16Amp @24vdc or 250vac
  • Connections - Screw Terminals for N/O N/C and Common contacts.
  • Free Android App available to remotely control this module.

LED indication

The ETH-RLY16 provides a red LED mounted immediately next to each relay to indicate whether it is in a powered state (LED on), there is also two LED's mounted in the Ethernet connector which will flash with Ethernet traffic. Finally there is green power LED just above the processor.
