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 consists of LED:s, 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.
Slot mounted PCB with A/D conversion.
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 communication
PMC board for IEC 61850 based communication.
Analog input module with 6 independent, galvanically separated
channels.
Used to provide the IED with GPS time synchronization.
Module with 2 inputs. One is used for handling both pulse-width
modulated signals and amplitude modulated signals and one is
used for optical input type ST for PPS time synchronization.
