Module Description
mA input module (MIM) Analog input module with 6 independent, galvanically
separated channels
GPS time synchronization module (GTM) Used to provide the IED with GPS time
synchronization and pulse per second (PPS) output
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.
23.2.2 Numeric module (NUM)
IP14288-1 v2
23.2.2.1 Introduction
M12643-3 v3
The numeric processing module (NUM) is a CPU module that handles all protection
functions and logic.
For communication with high speed modules, for example analog input modules and
high speed serial interfaces, NUM is equipped with a Compact PCI bus. NUM is a
compact PCI system card, that is, it controls bus mastering, clock distribution and
receives interrupts.
NUM provides up to 4 optical (type LC) or galvanic (type RJ45) Ethernet ports(one
basic and three optional).
23.2.2.2 Functionality
M12644-3 v5
The numeric module (NUM) is a high-performance CPU module based on a dual-core
processor. It is 6U high and occupies one slot. Contact with the backplane is achieved
via a compact PCI connector and an euro connector.
The NUM has two PC-MIP expansion slots where mezzanine cards, such as the
LDCM and OEM, can be mounted. It also has four SFP cages for Ethernet
communication. Up to four SFP transceivers for optical 100BASE-FX or galvanic
RJ45 100BASE-TX communication can be mounted in the SFP cages.
Only SPF transceivers approved by ABB (1MRK005500) are
compatible with the SFP cages.
Application code and configuration data are stored in flash memory, and non-volatile
RAM is used to store log data.
