Wireless Contact Closure Relay
The MirCR15 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 the input on the sender boards will control the relays on the receiver board.
The boards can communicate wirelessly with a line of sight distance of 2-miles! The MirCR15 has the 900HP 900 MHz Modules installed and are
paired together using the serial numbers of the radios installed. MirC boards operate reliably and efficiently when the antennas can "see"
each other. Obstructions like walls, buildings and even trees and hills can diminish the signal or prevent communication altogether.
