Overview
There are 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.
Free Android and Phone Apps are available to remotely control this module.
With inbuilt support for MQTT our ETH range on modules are compatible with, and easily integrated into many existing industrial, and household control systems.
The modules can publish certain status messages such as a power up message, or a heartbeat to a topic.
All of the I/Os on the modules can also subscribe, or publish, to a topic to control or monitor its state.
With the ability to send email notifications on input state changes via an outgoing email server it is easy to keep up to date with your systems activity.
Browser based configuration
Our ETH series modules all feature a simple, and comprehensive, browser based configuration and control interface.
There is no extra software you need to download to get started, simply point your browser at your modules IP address and begin configuring and controlling your module.
With the modules set to connect to a network via DHCP by default it could not be easier to get going. Just plug in the power and network cables and you are ready to go.
