Product Description
Ordering Key
AC current metering transformer for 25, 50, 100, 250 or
500 AAC. Output current from
the transformer is 0-20 mADC
or 4-20 mADC in accordance
with IEC 60381-1. Can be
used with relays DIB01,
PIB01, DIC01, PIC01 or
S183 or directly connected
to a PLC. Power supply ON
is indicated by a green LED
on the side of the housing.

Mode of Operation
A 82-10, A 82-20 are current
metering transformers with
standard source/sink output
0 - 20 mA/4 - 20 mA. This
makes it very useful as an
AC current interface to a
PLC with mADC input.
Used with relays DIB01,
PIB01, DIC01, PIC01 or
S183 one or more setpoints
can monitor the current and
signal alarm. S 183 also provides the DC voltage supply
for the A 82-10, A 82-20.
The metered conductor is
drawn through the central
hole of the current metering
transformer. It is possible to
meter currents below the
nominal range by drawing
the conductor through the
hole several times. If the
conductor is drawn through
the central hole e.g. 5 times,
the transformer will register
50 A when the current in the
conductor is 10 A.
A 82-10 has factory-set gain
(span) adjustment, whereas
A 82-20 has zero as well as
gain (span) adjustment, both
factory-set.
Note: Do not change the set
values.
