I need relays, and sensors to include it on schematic diagrams. . . . .But i cant find and schematic models for this . . .. . . .Wat shall i do friends. . .
Orcad what? P Spice, Capture? If you want Relays for Capture (schematics) that are not already in the library you create them and add them to the library.
You start Orcad Capture. Open the library you wish to add a new part to. Click Design and choose New Part. Then create the part. I use the demo addition at home so see the attached images. That should help.
