Auxiliary Output
Relays 3 to 6
The 350 relay is equipped with four auxiliary output relays numbered from 3 to 6. All these
relays are available for selection for operation of protection, control, or maintenance
features. Each auxiliary relay can be selected as either
Self-Reset
, or
Latched
. If the Self-
Reset type is selected, the output relay will be energized as long as the element is in
operating mode and will reset when the element drops out. If the Latched type is selected,
the output relay will stay energized, after the element dropout, and will be de-energized
upon the reset command.
