Wireless Contact Closure Relay
The MirXR420 Wireless Contact Closure Relay is a set of two boards with four contact closure inputs and fouro relays. The Contact closure input
controls the relay on the opposite board - wirelessly. A simple dry contact closure will connect to the input of the sender board and control
a corresponding relay on the opposite board - it's just that simple! Contact closure inputs such as buttons, relays, switches or other electronic
devices (no voltage) attached to input on the sender boards will control the relay on the receiver board.
