Binary signal transfer
SEMOD52522-4 v7
The remote end data communication is used for the
transmission of analog values for line differential protection or
for the transmission of only binary signals between IEDs. The
binary signals are freely configurable and can thus be used
for any purpose, such as communication scheme related
signals, transfer trip and/or other binary signals between
IEDs.
Communication between two IEDs requires that each IED is
equipped with a Line Data Communication Module (LCDM).
The LDCM then acts as an interface to 64 kbit/s and 2Mbit/s
communication channels for duplex communication between
the IEDs. In 2Mbit/s mode, each LDCM can send and receive
up to 9 analog and up to 192 binary signals simultaneously.
In 64kbit/s mode, the LDCM can be configured to work in
either analog mode or binary mode. In analog mode, the IED
can send and receive up to 3 analog signals and up to 8
binary signals. In binary mode, the LDCM can send and
receive only binary data (up to 192 binary signals).
The IED can be equipped with up to four short range, medium
range or long range LDCMs.
Line data communication module, short, medium and long
range LDCM
SEMOD168481-4 v10
The line data communication module (LDCM) is used for
communication between the IEDs situated at a distance <110
km/68 miles or from the IED to the optical-to-electrical
converter with G.703 or G.703E1 interface located at a
distance < 3 km/1.9 miles away. The LDCM module sends
and receives data to and from another LDCM module. The
IEEE/ANSI C37.94 standard format is used.
This feature can be used, for example, in power stations to
exchange up to 192 binary signals (e.g. tripping, signaling,
alarming) between the generator and HV station in power
plants.
Galvanic interface G.703 resp G.703E1
M16035-3 v5
The external galvanic data communication converter G.
703/G.703E1 makes an optical-to-galvanic conversion for
connection to a multiplexer. These units are designed for 64
kbit/s resp 2Mbit/s operation. The converter is delivered with
19” rack mounting accessories.

Hardware modules
IP14529-1 v1
Numeric processing module NUM
M12643-3 v3
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
M11595-3 v6
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
M1769-3 v4
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
M6938-3 v4
The binary output module has 24 independent output relays
and is used for trip output or any signaling purpose.
Static binary output module SOM
SEMOD174196-4 v4
The static binary output module has six fast static outputs
and six change over output relays for use in applications with
high speed requirements.
Binary input/output module IOM
M6939-3 v6
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
M15020-3 v4
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
M16073-3 v7
The optical Ethernet module (OEM) provides two additional
optical ethernet ports. The port connectors are of LC type.
Serial and LON communication module (SLM) for SPA/IEC
60870-5-103, LON and DNP 3.0
M14933-3 v5
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 fibre 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.
