New Contact Closure Over IP Coming Soon

The MirX Ethernet boards are currently unavailable.  NCD is no longer using the Lantronix modules and are transitioning to a new module that they will produce themselves.  The new versions will be network based only and will not have the ability to communicate over the internet.  A new user interface will allow manual input of the IP address in each board for them to communicate.  This will be a bit more work but for users with boards on different sub networks they will have the ability to operate without the need for internet access.

Contact Closure Over IP

MirX MXNET Contact Closure Over IP boards allow contact closure inputs to control relays in a remote location using a two board design.  Both boards are equipped with four contact closure inputs and four relays installed.  Each contact closure controls the relay on the opposite board.  Both boards are included when you purchase a MirX.

Contact Closure Input & Output

The relays on the receiver board can be used to interrupt the power of a device you are switching and also as a dry contact closure output.  Applications where you need to extend the range of a contact closure over a network the MirX will work.  Connect the Contact Closure (no voltage) output of your device to the one Board then wire the relays on the other Board as your contact closure input in a remote location on your network.

Selecting Contact Closure Over IP

Contact Closure Over IPBy selecting the Ethernet interface the boards will be communicating through your local area network.  Boards on this page are equipped with an Ethernet communication module that adds network communications to the boards.  Each board will plug directly into your router.  Initially both boards will be in DHCP mode so a managed network is required, at least for initial configuration.  It is not possible to configure these devices on an unmanaged switch, however after configuration is complete it is absolutely possible to install the boards on an unmanaged network.

Selecting a Contact Closure Over IP Relay

What amperage relay do you need?  MirX boards below have four inputs and four relays on each board.  You now have your choice of 5, 10, 20 or 30 amp relays installed.  Select the board with the amperage that you will require for more information and to purchase.  The 5-amp relay is the smallest we offer and can be used as a dry contact if needed.  For more information on selecting the correct relay for your application see Choosing a Proper Amperage.
