IED connectors

6.1.1.1

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.

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
Description
Module with 16 optically isolated binary inputs
Module with 24 single outputs or 12 double-pole command outputs
including supervision function
Module with 8 optically isolated binary inputs, 10 outputs and 2 fast
signalling outputs.
