Picture 9: Relay connection
Screw 12V is neccessary for relay powering (power 12-24V is possible
and DC or AC voltage) because telephone line has not enough power. Screw
12V is isolated from other components and not depends on polarity. Screw
marks COM is share output of switchable contact. Screw marks NO ( normaly
open) the contact in stand by is OFF and screw marks NC (normaly close) the
contact in stand by is ON. In configuration you can programm code and time for
relay switching.
Screw 12V is neccessary for LEDs and for correct function circuit for
push button(s).
