Figure 13-11. Current Differential Inputs, Schematic Diagram
The logic inside the ‘current differential’ block on the schematic is fixed as delivered from the factory
but can be custom ordered for your application. While the proven logic in the current differential relay
is not changed, the input and output signals of the current differential block can be customized to
provide different functionality for different applications.
The physical inputs (in this example Inputs 1 – 6) are mapped on the webpage to logic inputs. Any
physical input can be freely assigned to any number of logical inputs.
