Note for the ET-2260/2261/2261-16/2268:
When inductive loads are connected to the
relays, a large counter electromotive force may
occur when the relay actuates because of the
energy stored in the load. These fly back voltages
can severely damage the relay contacts and
greatly shorten the relay life. Limit these fly back
voltages at your inductive load by installing a
flyback diode for DC loads or a metal oxide
varistor for AC loads.
