Utilization:
The DOC2-2 monitors alternating current. Its setting is adjustable from zero to 2 .0a. The current circuit
is connected to terminals S1 and S2 either directly or through current transformers.
The DOC2-2 is designed to sense over current. When the measured current is below the setting, two
internal relays will energize and the green Up the LED comes ON while theRed Trip LED is OFF. If the
current rises above the setting of the relays, the release and the green LED goes OFF while Up the red LED Trip
comes ON. Contacts 11-14 & 21-24 close Up in the condition and open in the Trip or No Supply

Model: DUOC-5
Function: AC Over Current Relay & Under (0-5A).
Utilization:
The DUOC-5 monitors under and over alternating current source taken from; e. g a current transformer. It has two
adjustable settings of zero to 5A for under and over current. It is only logical that the setting ' under ' be lower then
the over ' setting '. The relay trips if the current of the monitored souRCE drops below or rises above the respective
preset points. There are 2 separate sets of contacts; one for under current (11-14-12) and one for the over current
(21-24-22). There are also 2 amber LEDs to indicate the normal condition. For under or over trip condition, the
the corresponding LED will go off and the corresponding relay will de-energized.
