ETH002 Ethernet Relay

Devantech

Overview

The ETH002 provides two 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. The ETH002 has additional features over the ETH-RLY02:

1. Full Factory Reset, all ETH002 firmware and settings can be reset to the original state.
2. Firmware updates, firmware in the ETH002 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.

Operating Temperature

-40°C to +70°C

LED indication

The ETH002 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 red power LED alongside the screw terminals.

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.

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

Mapped inputs

Digital inputs of the ETH484, ETH044, ETH8020 or WIFI484 are able to be configured to remotely control outputs on all of Devantech's new ethernet relay boards (both wired and WIFI), the older ETH-RLY02 and ETH-RLY16 are not compatible however. The mapped inputs offer simple linking and versatile usage, an input in one country can control a output in another, or across a small network.
Possible target boards are:

• ETH002
• ETH008
• ETH044
• ETH0621
• ETH484
• ETH8020
• WIFI002
• WIFI008
• WIFI484
• WIFI8020

The independent inputs can be mapped to different relays (on the same or different boards). As address of target board you can enter an IP address or hostname (which will be converted to an IP address by the DNS server supplied in the board configuration). If the module is on the local network then you can use the assigned IP address, if the target is over the internet then you need to supply the gateway in the configuration (internet source IP like your router) and the "Address of target board" is the IP address of the targets internet connection (to point at the router).
