Wired Contact Closure Switching
The MirXR820_ZRS Wired Contact Closure Switching is a set of two boards with one contact closure input and one relay. The Contact closure input
controls the relay on the opposite board through a 3-wire connection. A simple dry contact closure will connect to the input of one
of the boards and control a corresponding relay over a wired connection no more that 1000' (300 meters). Contact closure input such as
buttons, relays, switches or other electronic devices (no voltage) attached to inputs on either board will control the relay on the opposite board.
