Current Sensor for AC and DC currents
Put-on sensor with transistor-output
PNP
NPN
Technical Data
The current sensor S1 records
the current in a cable with a hall-
sensor. At currents of adjustable
5-30 A the transistor-outputs
switch and report a current in the
monitored cable.
The current sensor can be xed
with a cable fastener (apply to
only 1 cable). Thus it can be
mounted subsequently without
disconnecting the cable.
As supply-voltage DC 24 V are
required.
The current sensor can be con-
nected to ZIEHL current-relaysfor
current detection yes/ no ant to
ZIEHL controls for dedusting
plants. The connection to a digital
input of a PLC also is possible.
Application:
Recording of welding currents
(mounting at ground wire) for
controlling dedusting plants in
combination with ZIEHL-controls
type STW.
Recording of the state of a con-
sumer of electricity (on or o or
defective).
In general the current sensor S1 is
used where the current ow is to
be detected, with the exact value
of the current either known from
the power consumption of the
connected consumer or does not
matter for the evaluation.

For evaluation of measuring data in more than 1 cable,
the outputs of several current sensors can be con-
nected
in parallel (or-evaluation).
