The IED measures the analog signals needed for protection and measuring
functions via galvanically isolated matching transformers. The matching
transformer input channels 1…4 are intended for current measuring and channels
7...10 for voltage measuring.

3.2.4 Preprocessing blocks and fixed signals
The analog current and voltage signals coming to the IED are processed by
preprocessing blocks. There are two types of preprocessing blocks based on 20
samples per cycle and 80 samples per cycle. All function blocks functioning at 5
ms task time need 80 samples per cycle whereas all the rest need 20 samples per cycle.
A fixed signal block providing a logical TRUE and a logical FALSE output has
been used. Outputs are connected internally to other functional blocks when needed.
