ABB
Phasor measurement unit RES670
Pre-configured
Product version: 1.2
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.
