8-channel relay module (RJ45-RLY16, up to 16 amps)

Avaiability: In stock


The ETH008 provides eight volt free contact relay outputs with a current rating of up to 16Am. 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.

The ETH008 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 a green power LED just above the processor.
