21.2 Hardware modules
21.2.1 Overview
Table 638: 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.
Table 639: Application specific modules
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.
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.
Static output module (SOM) Module with 6 fast static outputs and 6 change over
output relays.
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.
