Ethernet Contact Closure
The MirXR45_MXNET Ethernet Contact Closure is a set of two boards with one contact closure input and one relay. The contact closure input
controls the relay on the opposite board over a network or over the internet. A simple dry contact closure will connect to the input of one
of the boards and control a corresponding relay over a local area network or across the Internet. Inputs such as
buttons, relays, switches or other electronic devices (no voltage) wired to inputs on either board will control the relay on the opposite board.
