Version 1.2.0
7.4.1.3 Overcurrent Limiting Factor FS
A current transformer’s overcurrent limiting factor (FS) indicates at which multiple
of the rated primary current saturation occurs with the current transformer for
protecting connected measuring instruments. The permissible FS is max. 10 for
the 1 A version and max. 5 for the 5 A version.
Do not exceed nominal input current of 1 A or 5 A
The I/O module must not be operated continuously with a load exceeding 1 A or
5 A.
If the overcurrent limiting factors for transformers in systems permit secondary
currents that are continuously higher than 1 A or 5 A, insert additional interposing
transformers with a corresponding transformation ratio.
