Bay control REC670 2.2
Product version: 2.2.1
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.
