Local human-machine interface (Local HMI)

Refer to section Local HMI
Transformer input module (TRM)
Introduction
The transformer input module is used to galvanically separate and adapt the secondary
currents and voltages generated by the measuring transformers. The module has twelve
inputs in different combinations of currents and voltage inputs.
Alternative connectors of Ring lug or Compression type can be ordered.
Design
The transformer module has 12 input transformers. There are several versions of the
module, each with a different combination of voltage and current input transformers.
Basic versions:
• 6 current channels and 6 voltage channels
• 7 current channels and 5 voltage channels
• 9 current channels and 3 voltage channels
• 12 current channels
• 6 current channels
• 10 current channels and 2 voltage channels
The rated values and channel type, measurement or protection, 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".
