The indicating relay type CV2 is intended for use in control and protective systems in industrial plants and power stations, where it is mainly used in conjunction with electronic control systems, particularly where a visual indication of a given function is required.
The indicating relay type CV2 is an instantaneous hinged-armature relay with two contacts. These may be either two normally open contacts, or one normally open and one normally closed. Two normally closed contacts cannot be supplied. The magnetic system comprises the fixed core and the hinged-armature which actuates the contacts. When the coil is de-energised, the armature is reset to its original position by a spring.
