Description
The ETH008-B module offers eight volt-free contact relay outputs capable of handling currents up to 16Am. It is designed to be powered by a 12vdc supply, which can either be regulated or unregulated. The DC input jack features a 2.1mm connector with a positive core polarity. To ensure proper functionality, the DC power supply should be capable of delivering at least 500mA at 12vdc. The relays utilized in this module are of the Single Pole Change Over (SPCO) type.
For easy accessibility, the screw terminals provide access to the normally open, normally closed, and common pins of each relay. To indicate the powered state of each relay, a red LED is mounted directly next to each one. Additionally, the Ethernet connector features two LEDs that flash in response to Ethernet traffic. Finally, there is a green power LED positioned just above the processor, serving as a visual indicator of the power status.
