ETH484-B Ethernet Relay

Devantech

ETH484 upgrade - New Version

The ETH484-B is a drop in update of the ETH484 with additional upgrades.

New features and improvements over the ETH484 are:

  1. 100mb full duplex Ethernet connection (ETH484 was 10mb half duplex)
  2. Hostname is now configurable
  3. MQTT with optional TLS encryption
  4. Email added with optional TLS encryption
  5. 12bit analogue converter, but old commands still return 10 bit results for compatibility


Overview

ETH484-B
Analogue Inputs 4 x 3.3v 12 bit or 10 bit for backward compatibility
Digital Switching I/O channels 8
Relays 4
Power 12V DC adaptor, supplied separately
Interface HTTP or TCP/IP over Ethernet
Relay current Up to 16Amp @24vdc or 250vac
Connections Screw Terminals for N/O N/C and Common contacts
Ethernet connection 100mb full duplex

Operating Temperature

-40°C to +70°C


LED indication

The ETH484-B 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 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.

Power Relays

Four 16A volt free contact relays are provided for switching a common input between a normally closed output and a normally open output. The relay coil is powered by the 12vdc incoming supply on user command.

Mapped inputs

Digital inputs of the ETH484, ETH484-B, 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). In the "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).

Examples

Java - command line application for controlling the module

Perl - Simple example of setting an output active/inactive by tcp

PHP Script - Simple example of setting an output active/inactive by tcp

Python V2 - command line application for controlling the module

Python V3 - command line application for controlling the module

Visual C# - source code for simple program, includes UDP scan to determine any boards connected to the local network


IO Network - Android and iPhone App

Devantech created the free app 'IO network', available for Android and iPhone to remotely control your relays. Download it from Google Play or iTunes. Search for "Devantech" and you will find the app.
