Type
<1> Refrain from assigning functions to digital 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).
<2> Connect a flywheel diode as shown in the Figure 3.23 when driving a reactive load such as a relay coil. Make sure the diode rating is greater
than the circuit voltage.
