<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 200,000 times (assumes 1 A, resistive load).
Connect a suppression diode as shown in Figure 3.26 when driving a reactive load such as a relay coil. Ensure the diode rating
is greater than the circuit voltage.
