0-5Vdc Current transducer
Technical Overview
The
PM-Hx22
series of current transducers can be used to
monitor motors, pumps or other electrical loads where a
linear voltage output signal is required. The output can be
used to check operating status, failure, wear/strain and
power for consumption analysis. The linear output signal is
produced by the unit which is proportional to the current
passing through the transducer.

0-5Vdc Current transducer
Installation notes (continued)
(Ring type shown). Fig 1.
Installation
1. The
PM-Hx22
range of current transducers should only
be installed by a competent, suitably trained technician,
experienced in installation with hazardous voltages.
(>50Vac & <1000Vac
or
>75Vdc & 1500Vdc)
2. Ensure that all power is disconnected before carrying out
any work on the
PM-Hx22
range. Never rely on status
indicating devices only to determine if power is present
in a conductor.
3. When installing the split-core version ensure that there
are no dirt particles that will prevent good contact be-
tween the core pieces when the device is closed.
4. Mount the sensor in a suitable location using the two
mounting holes in the base of the unit or use the self-
gripping iris which eliminates the need for drill mounting
(split core only).
5. Maximum output cable size is 2.5mm², care must be
taken not to over tighten the screw terminals.
6. Insure that the range selection slider is in the correct
position for the current being monitored. Excessive cur-
rent can damage the sensor.

Wiring example
Notes
Low conductor current:
If the load is low you can loop the conductor through the
sensor to provide adequate current and ensure accuracy.
Example:-
Load is 2.5A, pass the cable through the aperture 3 times
and you will have a total load of 7.5A and set the amp range
selector switch to 10A. See fig 1.
High conductor current and large diameter cables:
If the load is greater than the maximum specified for the
transformer or the cable diameter is greater than the aper-
ture of the current switch, you must use a suitable current
transformer. See fig 2.
Example:-
When monitoring loads greater than 200A (when using the
PM-H722HC), install a suitable CT with a 5A secondary.
Pass a cable connected to the secondary winding of the
current transformer through the aperture ten times and set
the amp range selector switch to 50A.
