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 two contact closure inputs and two relays installed.  Each contact closure triggers 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 distance the MirX will work.  Connect the Contact Closure 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 either on your LAN over the Internet.
