Table 628: 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. The
module provides four SFPs for Ethernet traffic.
Local Human machine interface (LHMI) The module consists of LEDs, 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) The module converts the VT and CT analog signals
from the TRM to digital signals processed by the NUM.
Carrier for communication boards.
Combined backplane module (CBM) 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.
Universal backplane module (UBM) The module is used to interconnect the TRM and the
ADM. It also connects the NUM with the LHMI

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.
Optical Ethernet module (OEM) Module used for Ethernet traffic. It has support for two
SFPs.
Optical Ethernet SFP Small form factor pluggable for Ethernet
communication
Galvanic RJ45 Ethernet SFPs Small form factor pluggable for Ethernet
communication
