The ETH008 is an 8-channel relay module controlled over Ethernet using TCP/IP commands or a built-in HTTP web interface. Each relay is rated up to 16A and features SPCO (Single Pole Change Over) contacts with normally open, normally closed, and common pins available on screw terminals. Individual red LEDs indicate the state of each relay.

The module is powered by a 12VDC supply (2.1mm jack, centre positive, minimum 500mA). Configuration and testing is available via the built-in web page, with control via TCP/IP over Ethernet. Free Android and iPhone apps are also available for remote control.
