Wireless Contact Closure Switching
The MIRCR820_ZRS relays are a set of two boards, a sender board and a receiver board. The Contact closure input on the sender board
controls the relay on the receiver board using a three wire connection. Close the contact closure on the sender board and a relay
will trigger on the receiver board - it's just that simple! 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.
MirCR820_ZRS The Ideal Choice
The MIRCR820_ZRS Contact Closure Relay is an ideal choice for a wired contact closure switch. The boards can communicate up to 1000
feet for reliable contact closure switching.
