2.5 Analogue output
The i4MC/V is
supplied with one analogue output, which can be set within the range 0 -
20mA or 0 - 10V. The analogue output can be configured to represent any of the
instantaneous measured values. The outputs can be set via the communications link.
The analogue module has two terminals (see TABLE 2-3).
Analogue output module with analogue
output, proportional to measured quantities.
The outputs may be either short or open-
circuited. They are electrically insulated from
each other and from all other circuits.

2.6 Auxiliary Supply
The i4MC/V Measuring transducer has a universal (AC/DC) auxiliary power supply.
Connection details and ratings are shown on a label as detailed in TABLE 2-4.
Connection of universal power supply to
terminals 13 and 14
TABLE 2-4: AUXILAIRY SUPPLY
NOTE: FOR SAFETY PURPOSES IT IS IMPORTANT THAT BOTH WIRES (LINE AND
NEUTRAL) ARE FIRMLY CONNECTED. THEY SHOULD BE CONNECTED ONLY TO
THE DESIGNATED TERMINALS AS SHOWN ON THE LABEL ABOVE AS WELL AS ON
THE FRONT LABEL OF THE TRANSDUCER.
2.7 Measurement Inputs
The Voltag
e input of the i4MV can be connected directly to low-voltage networks or via an
appropriate voltage transformer to medium or high voltage networks.
The Current inputs of the i4MC can be connected directly to low-voltage networks or via a
current transformer.
The wiring connections are shown in section 7.
The i4MC/V has an auto-ranging voltage or current input with nominal values of 500V and
5A.
