Basic modules
Module Description
Power supply module (PSM) Including a regulated DC/DC converter that supplies auxiliary
voltage to all static circuits.
• An internal fail alarm output is available.
Numerical module (NUM) Module for overall application control. All information is
processed or passed through this module, such as configuration,
settings and communication.
Local Human machine interface (LHMI) 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 input module (TRM) Transformer module that galvanically separates the internal
circuits from the VT and CT circuits. It has 12 analog inputs.
Analog digital conversion module (ADM) Slot mounted PCB with A/D conversion.

Module Description
Binary input module (BIM) Module with 16 optically isolated binary inputs
Binary output module (BOM) Module with 24 single outputs or 12 double-pole command
outputs including supervision function
Binary I/O module (IOM) Module with 8 optically isolated binary inputs, 10 outputs and 2
fast signalling outputs.
Line data communication modules (LDCM),
short range, medium range ,long range,X21
Modules used for digital communication to remote terminal.
Serial SPA/LON/IEC 60870-5-103
communication modules (SLM)
Used for SPA/LON/IEC 60870–5–103 communication
Optical ethernet module (OEM) PMC board for IEC 61850 based communication.
mA input module (MIM) Analog input module with 6 independent, galvanically separated
channels.
GPS time synchronization module (GSM) Used to provide the IED with GPS time synchronization.
IRIG-B Time synchronization module (IRIG-B) 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.
