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 two optical
ports with ST connectors.
Galvanic RS485 serial communication module
The Galvanic RS485 communication module (RS485) is used
for DNP3.0 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 transform 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.
