Figure 19. Flyback Diode Wiring

FLYBACK DIODE WIRING

It is good engineering pratice to include a flyback diode when switching an inductive

load (seloniod coil, relay coil, electric motor winding, etc.). It is recommended that a
flyback diode be installed on inductive devices that share a common power source/
ground with a FRC governor.

Typical circuit showing a flyback diode

installed across an inductive load.
