Note:
In case of connected inductive load (such as electromotor, coil of a relay or contactor or even power cabling
in complex electro installations) it is recommended to protect relay outputs with an appropriate external
component (e.g. varistor, RC circuit, or diode with an appropriate characteristics).
In case of connected capacitive load (such as power supplies for LED lightning) it tis recommended to protect
the contacts of the relay against the current surge with a thermistor connected in series with the output of
the relay with appropriate characteristics.
The following figure illustrates the connection of an ohmic (resistive) load with alternating voltage to the
relay output:
