Contact Closure Over IP

MirX MXNET controllers allow contact closure inputs to control relays in a remote location using a two board design.  Both boards are equipped with two contact closure inputs and two relays installed.  Each contact closure controls a relay on the opposite board so both relays are independently controlled.  Boards will find each other on a Local Area Network or over the internet if they are located outside the network.

Contact Closure Input & Output

The relays on the sender 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 with relays at both locations the MirX will work.  Connect the Contact Closure output of your device to a contact closure input then wire the relay on the opposite board as your contact closure output in a remote location.

Selecting a Wireless Contact Closure Relay

MirX boards boards below have two relays installed and two contact closure inputs.  You now have your choice of 5, 10, 20 or 30 amp relay installed.  A simple dry contact closure will connect to the input of either board and trigger a corresponding relay on the opposite board.  These are sold as a pair and they are paired using the MAC Addresses of the ethernet modules on-board so multiple MirX boards will not interfere with each other.  For more information on selecting the correct relay for your application see Choosing a Proper Amperage.
