Overview

The quantity and designation of connectors depend upon the type and size of the IED. The rear
cover plates are prepared with space for the maximum of HW options for each case size and the
cut-outs that are not in use are covered with a plate from factory.

Basic modules
Description
Including a regulated DC/DC converter that supplies auxiliary
voltage to all static circuits.
• An internal fail alarm output is available.
Module for overall application control. All information is
processed or passed through this module, such as configuration,
settings and communication. The module provides four SFPs for
Ethernet traffic.
The module consists of LEDs, an LCD, a push button keyboard and
an ethernet connector used to connect a PC to the IED.
Transformer module that galvanically separates the internal
circuits from the VT and CT circuits. It has 12 analog inputs.
The module converts the VT and CT analog signals from the TRM
to digital signals processed by the NUM. Carrier for
communication boards.
Note: TRM module is not included in SAM600-IO, so ADM module
is only used for internal communication carrier for IO modules.
The module has two main purposes: to distribute supply voltages
from the PSM to the other modules and to act as a
communication carrier via its two buses, CompactPCI for fast I/O
and communication and CAN for slow I/O.
The module is used to interconnect the TRM and the ADM. It also
connects the NUM with the LHMI
