When an E-Plex power module such as an 805OPM is used to power a load and that load may also be powered from another power source, a potentially damaging back feed situation is possible. The 821BD can be used to prevent the back feed from causing any damage, whilst still allowing the E-Plex module to detect if the auxiliary supply is active.
