Selecting the Proper Amperage

For more information on selecting a board with the correct relay amperage for your application see Choosing a Proper Amperage.

Selecting The Ethernet Relay Interface

By selecting the Ethernet interface you will be sending commands through your local area network or internet to the board.  Boards on this page are equipped with the new NCD5500 communications module that adds Ethernet communications to the board.  The Ethernet to Serial Communications Module converts TCP packets to Serial data and vise versa.  This device can be configured to automatically close the socket after a programmable timeout or to leave the socket open.  A blue LED light indicates an open socket connection.  Program the Baud Rate of this Device from 9600 to 115.2K Baud and communicate to this device over the default TCP port 2101.  This device also supports Static IP Addresses, DHCP, and has the ability to recover back to factory default settings with a simple press of a button!

Selecting an Ethernet Relay Series

Ethernet RelayThe 2-Channel boards are available in the ProXR Lite and ProXR versions. Both versions have the same firmware installed and accept the same ProXR command set, the industry leading command set for controlling relays.  The ProXR Lite version is non-expandable, the ProXR version is expandable to 256 relays.  When you find your controller click on the Full Description link to view full specs, watch setup videos, download software and purchase.

Selecting an Ethernet Relay Board

What amperage relay do you need?  Below you will find the 2-channel Ethernet Relay that are available.  The difference being the amperage of the relays installed and the type of relay.  Choose the controller that fits the amperage you are switching.  You will find SPDT relays in the 5, 10 and 20 amp versions and an SPST version in 30 amp.  For more information on selecting the correct relay for your application see Choosing a Proper Amperage.
