Snubber
Relay Outputs can be used with snubbers. To use with snubber,
the terminals 2 and 3 should be short circuited with a suitable cable.
Snubber consist of serially connected a capacitor (10nF, 630 V)
and a resistance (100
, 1/4 W) and can be used to suppress the
contact noise.
While the contact is used for switching AC signals and snubber is
connected, impedance of the snubber should be taken into
consideration.
