Breaker protection REQ650 2.1 IEC
Product version: 2.1
Optical ethernet module OEM
The optical fast-ethernet module is used for fast and
interference-free communication of synchrophasor data over
IEEE C37.118 and/or IEEE 1344 protocols. It is also 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.
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.
IRIG-B Time synchronizing module
The IRIG-B time synchronizing module is used for accurate
time synchronizing of the IED from a station clock.
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.
