Transformer protection RET650
Version 2.2
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.
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.
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.
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.
The Pulse Per Second (PPS) input is supported.
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
36
twelve inputs in different combinations of currents and
voltage inputs.
Ring lug or compression type connectors can be ordered.
