IED hardware
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
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.
Modules used for digital communication to remote
terminal.
Used for SPA/LON/IEC 60870–5–103
