ETH-RLY16 - 8 relay outputs at 16A

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.

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.

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.

load type Typical applications Rating Max DC load capacity
AC1 Non inductive or slightly inductive loads 16A @ 250V AC
AC15 Control of electromagnetic load (>72VA) 3A @ 120V AC 1.5A @ 240V AC
AC3 Control of motor 750W
DC1 Non inductive or slightly inductive loads 16A @ 24V DC
DC13 Control of electromagnetic loads 0.22A @ 120V DC 0.1A @ 250V DC

Summary:

- Configuration SPDT relay
- Each relay output is capable of controlling loads up to 16A
- Requires 12VDC power supply 500mA
- There is an internal webserver that allows you to set the relay logic
- Supports static IP settings afford dynamic
