<1> Refrain from assigning functions to digital relay outputs that involve frequent switching, as doing so may shorten relay performance life. Switching
life is estimated at 100,000 times (assumes 2 A, resistive load).
Connect a suppression diode as shown in Figure i.15 when driving a reactive load such as a relay coil. Ensure the diode rating
is greater than the circuit voltage.
