Product version: 1.1
via the RTD or mA inputs and provides four
mA outputs. The RTD and mA inputs can for
instance be used for measuring oil
temperature at the bottom and top of the
transformer tank and the ambient air
temperature or supervision of analog signals
provided by external transducers. An RTD
input can also be used as a direct resistance
measuring input for position tracking of an on-
load tap changer. Alternatively, tap changer
position can be obtained via a mA transducer.
The RTD/mA inputs can also be used as an
input for DC voltage transducer. The RTD/
mA module enables the use of the
multipurpose protection functions. These
protection functions can be used for tripping
and alarm purposes based on RTD/mA
measuring data, or analog values
communicated via GOOSE messaging. The

mA outputs can be used for transferring
freely selectable measured or calculated
analog values to devices provided with mA
input capabilities.
The enhanced scalability of the 6U variant
IEDs are intended for optimized medium
voltage metal-clad switchgear applications
where additional binary inputs and outputs
are often required.
All binary input and output contacts are
freely configurable using the signal matrix of
the application configuration function in
PCM600. Please refer to the Input/output
overview tables, the selection and ordering
data, and the terminal diagrams for more
detailed information about the inputs and
outputs.
