The isolated communications interface on the Protégé® SE Integrated System
Controller uses full galvanic isolation to prevent ground loop noise and cross phase
ground differential. This is a very important feature of the product family and the
correct connection of power to this isolated section will ensure the correct
operation of the communications network.
13.1 Current and Validation Example 1
The example shown below refers to the specification’s table needed to help ensure the correct
installation of the Protégé® SE Integrated System Controller. Specifications have to be validated to
ensure that individual maximum currents and total combined current are not exceeded.
