I want to model electric scheme in OrCAD from an image and I stuck on element K1 (surrounded by the red rectangle). What is this element, why do we need it, and can I find it in standard OrCAD library?
K1 is a relay coil. The coil is the black rectangle and the contacts are on the right (K1.3=NO/K1.2=COM/K1.1=NC). VD2 is the flyback or catch diode.
K is usually used for relay names on schematics.
