IED connectors

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.

Table 2: Basic modules
Module
Power supply module (PSM)
Numerical module (NUM)
Local Human machine interface (LHMI)
Transformer input module (TRM)
Analog digital conversion module (ADM)
Combined backplane module (CBM)
Universal backplane module (UBM)
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.
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
