The
closure when used in series with telecom
devices on analog phone lines. The
will initiate a dry relay contact on any off-hook
condition. Alternatively, add the optional
power supply to provide switched DC power.
The relay itself is phone line powered and
does not need an external power supply.
Because both TIP and RING currents flow
through the relay, excellent line balance is
maintained.
