Hardware modules
Power supply module PSM
The power supply module is used to provide
the correct internal voltages and full isolation
between the terminal and the battery system.
An internal fail alarm output is available.
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 signalling
purpose. The two high speed signal output
1MRK 504 091-BEN B
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 OEM
The optical fast-ethernet module is used to
connect an IED to the communication buses
(like the station bus) that use the IEC
61850-8-1 protocol (port A, B). The module
has one or two optical ports with ST
connectors.
Serial SPA/IEC 60870-5-103 and LON
communication module SLM
The optical serial channel and LON channel
module is used to connect an IED to the
communication that use SPA, LON, or
IEC60870–5–103. The module has two optical
ports for plastic/plastic, plastic/glass, or glass/
glass. One port is used for SPA and IEC
60870-5-103 one port is used for LON.
Line data communication module LDCM
Each module has one optical port, one for
each remote end to which the IED
communicates.
Alternative cards for Medium range (1310 nm
single mode) and Short range (850 nm multi
mode) are available.
