ETH-RLY16 - 8 relay outputs at 16A

ETH-RLY16 Hardware Revisions
This documentation is for the latest Hardware revision, marked as ETH-RLY16 V3 on the side of the PCB near Relay number 8. 
If you have an older PCB marked just as ETH-RLY16 (with no hardware revision number) then please click here for the documentation.

Overview
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

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.

Relay power rating
If the contact load voltage and current of the relay are in the region enclosed by the solid and dotted lines in the figure below, the relay can perform stable switching operation. If the relay is used at a voltage or current exceeding this region, the life of the contacts may be significantly shortened.
