Electrical Designer - Representing Black Box Devices in Multiple Ways

A black box device such as an emergency stop relay can often be represented in a multitude of ways dependent upon the customer.

The device may be shown:

1. As a one unit in the schematics
2. As a primary device in one drawing with secondary contacts being displayed separately on different pages
3. As a primary device on one drawing (e.g. power part) and the secondary (control) part on a different drawing.

In this Electrical Designer tips and tricks we will look at how each method is achievable.
