Wireless Contact Closure Relay
The MirCR430 Wireless Contact Closure Relays are a set of two boards, a sender board with four contact closure (no voltage) inputs and a receiver board
with four relays. The inputs on the sender board will control the relays on the receiver board - it's just that simple! 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 control the relays on the receiver board.
