DI19/DI20 (option)
The DI19/DI20 option enables two more digital inputs. These
inputs are very useful in applications where both positive and
negative terminals are needed. For example, change of
directional earth fault characteristic in the compensated
networks. The inputs are connected to terminals X6:1 – X6:2
and X6:3 – X6:4.
NOTE!
With DI19/DI20 option only one arc sensor channel can be
activated. Both of the digital inputs must have their own
common.
