Contact Closure Over Ethernet
The MirCR220_MCNET Contact Closure Over Ethernet are a set of two boards, a sender board with contact closure (no voltage) inputs and a receiver board
with relays. The inputs on the sender board will control the relays on the receiver board - it's just that simple! Plug both boards into
the network and they will find each other! When the contact closure circuits are closed the relays will remain energized, when the circuits
open the relays will turn off! Contact closure inputs such as buttons, relays, switches or other electronic devices (no voltage) attached to
inputs on the sender boards will trigger the relays on the receiver board. The boards can communicate between offices, buildings or cities!
