Wireless Contact Closure Relay
The MirXR210 Wireless Contact Closure Relay is a set of two boards with two contact closure inputs and two 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.
