Product Description
Small AC current metering
transformer with 7 knob se-
lectable ranges. Output from
the transformer is 4-20
mADC in accordance with
IEC 60381-1. Can be used
with relays DIB01, PIB01,
DIC01 or PIC01 or directly
connected to a PLC.
Power supply ON is indicat-
ed by a green LED.
12 mm hole for isolated cur-
rent carrying wire makes it
suitable for most applica-
tions. For mounting on DIN-
rail or directly on surface by
screws.

Mode of Operation
The E 83-20 is a small AC
current metering transformer
with standardized 4-20
mADC output. This makes it
very useful as an AC current
interface to a PLC with 4-20
mADC input.
Used with relays DIB01,
PIB01, DIC01 or PIC01, one
or moresetpoints can moni-
tor the current and signal
alarm.
In the 5 A range the E 83-20
is often used as a 4-20
mADC signal converter for
larger standard AC current
transformers with 5 AAC
secondaryoutput.
The metered conductor is
drawn through the central
hole of the current metering
transformer.It is possible to
measure 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
5AAC when the current in
the conductor is 1 AAC.
