Picture 4: Relay connection
Screw 12V is necessary for relay powering 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 ( normally open) the contact in stand by is OFF and screw
marks NC (normally close) the contact in stand by is ON. In configuration you
can program code and time for relay switching.
