ETH044 - 4 x 5A SSR

Devantech

WARNING
Mains Voltages can be Lethal.
If you are not confident with using these voltages, please use a qualified electrician to wire this up for you.

Overview

The ETH044 provides four solid state relay outputs at 230VAC with a current rating of up to 5Amps per channel and up to 10Amps total per module, 4 digital IO channels are also provided for flexible additional functionality. The ETH044 module is powered directly from a 230VAC mains supply at either 50hz or 60hz, the live, earth and neutral outputs for each channel are brought out to screw terminals, while the live is the only output that is switched the neutral and earth are provided for easy wiring. Each channel uses phase angle controlled switching for dimmable lighting.
A feature is also implemented (input mapping) that allows the digital inputs to remotely control relays or digital outputs on other ETHxxx(x) series modules such as the ETH008 etc. 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

-30C to +70C

LED indication

The ETH044 provides a red LED mounted immediately next to each SSR and the intensity will increase with power output, each digital IO has a red LED to reflect the channel status, 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.

SSR switching capabilites

A datasheet for the SSR provides a full description of maximum switching capabilities.

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).

Control via ASCII-commands and also a long requested feature of control via http is possible with all available firmware versions. 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).

Connections

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).
