Contact Closure Over IP

MirC MCNET Contact Closure Over IP boards allow contact closure inputs to control relays in a remote location using a two board design. The sender board is equipped with contact closure inputs, used to control relays on the receiver board.  Both sender and receiver boards are included when you purchase a MirC pair.

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 MirC will work.  Connect the Contact Closure output of your device to the Sender Board then wire the relays on the Receiver Board as your contact closure input in a remote location either on your LAN over the Internet.
