Contact Closure Over IP

MirC MCNET controllers 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 relay 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 relay on the Receiver Board as your contact closure input in a remote location either on your LAN over the Internet.

Selecting a Contact Closure Over IP Relay

MirC boards boards below have one relay installed and one contact closure input.  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 the sender board and trigger a corresponding relay on the receiver board.  These are sold as a pair and they are paired using the MAC Addresses of the Lantronix Pro Ethernet Modules installed so multiple MirC boards on a network will not interfere with each other.  For more information on selecting the correct amperage relay for your application see Choosing a Proper Amperage.
