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 four optical Ethernet ports of type LC (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 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 LC type.
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 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.
Line data communication module LDCM
Each module has one optical port, one for each remote end to
which the IED communicates.
Alternative modules for Long range (1550 nm single mode),
Medium range (1310 nm single mode) and Short range (850 nm
multi mode) are available.
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 GPS 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.
Electrical (BNC) and optical connection (ST) for 0XX and 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.
Alternative connectors of Ring lug or Compression type 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 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.
