Design

The transformer module has 12 input transformers, 7 voltage and 5 current input
transformers.
The rated values and channel type of the current inputs are selected at order.
Transformer input module for measuring should not be used with
current transformers intended for protection purposes, due to
limitations in overload characteristics.
The TRM is connected to the ADM and NUM.
For configuration of the input and output signals, refer to section
analog inputs SMAI".
