The ETH002 is an update of the ETH-RLY02 board. The ETH002 can be more easily updated with new firmware and there is also a new command set option (in addition to legacy commands) that allows the relay to pulse for a specified duration (100ms to 25.5s with a 100ms resolution).

The ETH002 is a relay module board that provides 2x volt free contact relay outputs each having a current rating of up to 16A each. Required power for the module is 12V DC 500mA and the supply can be regulated or unregulated. Both the relays are of the SPCO (Single Pole Change Over) type and the normally open, normally closed and common pins are all available on screw terminals.

The relay module is controlled via Ethernet using simple TCP/IP commands and there are various LED indicators to report on performance, one next to each relay to indicate the relay is powered, two LEDs mounted in the Ethernet connector indicating Ethernet traffic and there is a red power LED adjacent to the screw terminals.

Devantech produce great modules that allow those capable to solve tricky problems. I recently changed over a garage to VoIP phones and they still needed the loud bell to ring when a phone call came in. The VoIP solution costs upwards of £250 I set-up the main incoming VoIP phone to close a relay on the ETH002 when an incoming call is active and open the relay when the handset is lifted. Works a treat and costs a fifth of the price of the official way to do it.
