21.2 Hardware modules
21.2.1 Overview
Table 884: 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.

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.
