ETH484 Ethernet Relay

Devantech

Overview

The ETH484 provides four volt free contact relay outputs with a current rating of up to 16Amp each, 8 digital I/O and 4 analogue inputs. 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. A new feature has been added that allows the digital inputs to remotely control relays or digital outputs on ETH008, ETH484 or ETH8020. This offers the opportunity to construct a system where an input can control an output anywhere on the earth provided both locations are connected to the network/internet.


Operating Temperature

-40°C to +70°C


LED indication

The ETH484 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.

Control

The relay board communicates via TCP/IP and is controlled with a set of commands, which are sent to the board's IP-address on a configurable port. The commands are sequences of bytes, for example:
The sequence 0x20, 0x01, 0x32 will turn on relay number 1 for 5 seconds. A full specification can be found at the manufacturer's spec (see link below).

Newer firmware versions allow control via ASCII-commands and also a long requested feature of control via http. For example: Sending a http GET to
192.168.0.200/io.cgi?DOI1=10
sets relay 1 on active for 1 second (This would use the default address 192.168.0.200). You can test these functions by typing them directly into the address bar of most internet browsers. Also be aware that you may need to disable http authentication in the http configuration if your control device does not support it. A full specification and firmware updates can be found at the manufacturer's spec (see link 'Technical Specification' below).

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:


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).
