Version 2.2
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.
Ethernet ports can be configured as two separate or in
redundant mode PRP or HSR.
The optical Ethernet module (OEM) provides two additional
optical Ethernet ports. The port connectors are:
• SFP Optical LC
• Galvanic RJ45
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
M1769-3 v4
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
M6938-3 v4
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
SEMOD174196-4 v5
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
M6939-3 v6
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.
M15020-3 v4
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
M16073-3 v10
12X IRIG-B support.
Transformer input module TRM
The transformer input module is used to galvanically
separate and adapt the secondary currents and voltages
generated by the measuring transformers. The module has
twelve inputs in different combinations of currents and
voltage inputs.
Ring lug or compression type connectors can be ordered.
High impedance resistor unit
The high impedance resistor unit, with resistors for pick-up
value setting and a voltage dependent resistor, is available
M14933-3 v6
in a single phase unit and a three phase unit. Both are
mounted on a 1/1 19 inch apparatus plate with compression
type terminals.
