Types of Additional Transient Protection
DC Coils:
The most effective protection against transients from a DC coil is a flyback diode. A flyback
diode can reduce the transient to roughly 1V over the supply voltage, as shown in this example.
Many AutomationDirect socketed relays and motor starters have add-on flyback diodes that
plug or screw into the base, such as the AD-ASMD-250 protection diode module and
784-4C-SKT-1 socket module shown below. If an add-on flyback diode is not available for your
inductive load, an easy way to add one is to use AutomationDirect's DN-D10DR-A diode
terminal block, a 600VDC power diode mounted in a slim DIN rail housing.
