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.
