Wireless Contact Closure Relay
The MirCR110 Wireless Contact Closure Relays are a set of two boards, a sender board with one contact closure (no voltage) input and a receiver board
with one relay. The input on the sender board will control the relay on the receiver board - it's just that simple! When the contact closure
circuit is closed the relay will remain energized, when the circuit opens the relay 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 control the relay on the receiver board.
