Overview
The ETH008 provides eight volt free contact relay outputs with a current rating of up to 16Amp each. 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 is fully compatible with the ETH-RLY16 and includes the legacy ETH-RLY16 command set.
The ETH008 has additional features over the ETH-RLY16:
1. Full Factory Reset, all ETH008 firmware and settings can be reset to the original state.
2. Firmware updates, firmware in the ETH008 is fully updateable by re-flashing the board with our custom windows program. This will be made available in the event of feature updates.
3. New Command Format, the new command format allows for consistent compatibility with future boards. New commands now allow for pulsed control of relays from 100mS to 25.5 seconds.
4. TCP/IP Password Protection, it is now possible to set a password for TCP/IP protection. This is independent of the configuration password.
Features
- Number of Relays: 8
- Power: 12V DC adapter, supplied separately
- Configuration & Test interface – HTTP (webpage)
- Control interface: TCP/IP over Ethernet
- Operating Temperature: -40C to +70C
LED Indication
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 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.
First Test
Having plugged in your 12vdc power supply and Ethernet connection, start up your web browser and type http://eth008 into the address bar, please note this only works in windows.
