Hardware modules
Numeric processing module NUM
The numeric processing module (NUM) is a CPU module
that handles all protection functions and logic.
NUM provides up to 4 optical (type LC) or galvanic (type
RJ45) Ethernet ports(one basic and three optional).
Power supply module PSM
The power supply module is used to provide the correct
internal voltages and full isolation between the IED and
the battery system. An internal fail alarm output is
available.
Alternative connectors of Ring lug or Compression type
can be ordered.
Binary input module BIM
The binary input module has 16 optically isolated inputs
and is available in two versions, one standard and one
with enhanced pulse counting capabilities on the inputs
to be used with the pulse counter function. The binary
inputs are freely programmable and can be used for the
input of logical signals to any of the functions. They can
also be included in the disturbance recording and event-
recording functions. This enables extensive monitoring
and evaluation of operation of the IED and for all
associated electrical circuits.
Binary output module BOM
The binary output module has 24 independent output
relays and is used for trip output or any signaling
purpose.
Static binary output module SOM
The static binary output module has six fast heavy-duty
static outputs and six change over output relays for use
in applications with high speed requirements.
Binary input/output module IOM
The binary input/output module is used when only a few
input and output channels are needed. The ten standard
output channels are used for trip output or any signaling
purpose. The two high speed signal output channels are
used for applications where short operating time is
essential. Eight optically isolated binary inputs cater for
required binary input information.
mA input module MIM
The milli-ampere input module is used to interface
transducer signals in the –20 to +20 mA range from for
example OLTC position, temperature or pressure
transducers. The module has six independent,
galvanically separated channels.

Optical Ethernet module
The optical Ethernet module (OEM) provides two
additional optical Ethernet ports. The port connectors
are of optical (type LC) or galvanic (type RJ45) Ethernet
ports.
Serial and LON communication module (SLM) for SPA/IEC
60870-5-103, LON and DNP 3.0
The Serial and LON communication module (SLM) is
used for SPA, IEC 60870-5-103, DNP3 and LON
communication. SLM has two optical communication
ports for plastic/plastic, plastic/glass or glass/glass
fiber cables. One port is used for serial communication
(SPA, IEC 60870-5-103 or DNP3 port) and the other port
is used for LON communication.
Line data communication module LDCM
Each module has one optical port, one for each remote
end to which the IED communicates.
Alternative modules are:
Short range LDCM (820 nm multi mode fiber),
Medium range (1310 nm single mode fiber)
and Long range (1550 nm single mode fiber) .
Galvanic RS485 serial communication module
The Galvanic RS485 communication module (RS485) is
used for DNP3.0 and IEC 60870-5-103 communication.
The module has one RS485 communication port. The
RS485 is a balanced serial communication that can be
used either in 2-wire or 4-wire connections. A 2-wire
connection uses the same signal for RX and TX and is a
multidrop communication with no dedicated Master or
slave. This variant requires however a control of the
output. The 4-wire connection has separated signals for
RX and TX multidrop communication with a dedicated
Master and the rest are slaves. No special control signal
is needed in this case.
GPS time synchronization module GTM
This module includes a GPS receiver used for time
synchronization. The GTM has one SMA contact for
connection to an antenna. It also includes an optical PPS
ST-connector output.
IRIG-B Time synchronizing module
The IRIG-B time synchronizing module is used for
accurate time synchronizing of the IED from a station
clock.
The Pulse Per Second (PPS) input is supported.
Electrical (BNC) and optical connection (ST) for 0XX and
12X IRIG-B support.
