The 2C65 Series relay is a three-pole current detector with independently adjustable sensing circuits driving a common adjustable digital setting timing element. Five (5) status inputs & eight (8) relay outputs are provided as standard to allow the 2C65 to be operated in a number of different configurations: ♦ Time delayed or instantaneous output contacts; ♦ Phase segregated or 3 phase output contacts; ♦ Single phase or 3 phase current initiation inputs; ♦ Timer initiate input logic; After pick up & time out the latching target indicator (LED or magnetic flag), is set. The flag may be reset at the front panel or remotely reset via a status input. Fully solid-state sensing & measuring circuitry is employed with each phase current setting continuously adjustable on a front panel control. Air core CT’s are employed to provide a very fast reset characteristic. The wide range switchmode power supply, input current transformer, output relays & status inputs form the essential barriers against high voltage line transients. Instantaneous Operation Version The 2C65 may be specified without the integrated delay timer for instantaneous current check function. Zero Stand by Burden Relay The 2C80 current check relay may be specified where a zero stand by burden is required. Initiation of the relay is achieved through application of the auxiliary supply on a single or three phase basis. The linear power supply provides high speed start up but results in higher operating burden & non continuous rating. The 2C80 may be specified with or without an integrated time delay element.
