1 Safety instructions
Appropriate use
The PMX amplifier system is to be used exclusively for
measurement tasks and directly related control tasks.
Use for any purpose other than the above is deemed to
be non-designated use. In the interests of safety, the
device should only be operated as described in the
Operating Manuals. It is also essential to comply with the
legal and safety requirements for the application
concerned during use. The same applies to the use of
accessories.
Each time, before starting up the equipment, you must
first run a project planning and risk analysis that takes
into account all the safety aspects of automation
technology. This particularly concerns personal and
machine protection.
Additional safety precautions must be taken in plants
where malfunctions could cause major damage, loss of
data or even personal injury. In the event of a fault, these
precautions establish safe operating conditions.
Safety instructions
This can be done, for example, by mechanical
interlocking, error signaling, limit value switches, etc.
Notice
The device must not be directly connected to the DC
voltage supply system. Supply voltage 10 V … 30 V
(DC).
Before commissioning, ensure that a suitable supply
voltage is used and that the circuit used is sufficiently
protected.
PMX A4354-2.2 HBM: public 13
Safety instructions
The device may only be supplied with separated extralow voltage (safety isolating transformer according to DIN
VDE 0551 / EN60742). Only operate built-in devices once
they are installed in the housing provided. The device
development is based on DIN EN 61010 Part 1 (VDE
0411 Part 1).
General dangers of failing to follow the safety
instructions
The PMX system is a state of the art unit and as such is
reliable. The module may give rise to dangers if it is
inappropriately installed and operated by untrained
personnel.
Any person instructed to carry out installation, starting up,
maintenance or repair of the module must have read and
understood the Operating Manual and in particular the
technical safety instructions.
Conditions at the place of installation
S Protect the device from direct contact with water.
S Protect the PMX system from moisture and humidity
or weather conditions such as rain, snow, etc.
S Do not expose the device to direct sunlight.
S Please observe the permissible maximum ambient
temperatures stated in the specifications.
S The permissible relative humidity at 31 °C is 95 %
(non condensing); linear reduction to 50 % at 40 °C.
S Install the device so that it can be disconnected from
the supply voltage at any time without difficulty.
S It is safe to operate the PMX system up to a height of
2000 m.
14 A4354-2.2 HBM: public PMX
Safety instructions
Maintenance and cleaning
The PMX system is maintenance-free.
S Before cleaning, disconnect all connections.
S Clean the housing with a soft, slightly damp (not wet!)
cloth. You should never use solvents, since these
could damage the labeling.
S When cleaning, ensure that no liquid gets into the
module or connections.
Residual dangers
The scope of supply and performance of the PMX system
only covers a small area of measurement technology. In
addition, equipment planners, installers and operators
should plan, implement and respond to the safety
engineering considerations of measurement technology
in such a way as to minimize remaining dangers. On-site
regulations must be complied with at all times. There
must be reference to the remaining dangers connected
with measurement technology.
Product liability
In the following cases, the protection provided for the
device may be adversely affected. Liability for device
functionality then passes to the operator:
S The device is not used in accordance with the
operating manual.
S The device is used outside the field of application
described in this Chapter.
S The operator makes unauthorized changes to the
device.

4 PMX product description
By buying the PMX measuring amplifier system, you
have chosen a high-quality HBM measurement system
that is compact, powerful and variable. The data rate for
all the measurement and calculation channels is 19,200 /
38,400 measurements per second. The device thus
achieves an overall processing rate of approx. 400,000
measured values per second.
Numerous different measurement, control and
automation tasks can be resolved with this measurement
system.
Connection to a PC (HOST)
The PMX measuring amplifier system is connected to a
PC via the standard ETHERNET interface, and can be
parameterized and operated via the internal web server.
The link to an automation system can be connected via
digital and analog inputs/outputs, as well as over the
fieldbus interfaces of the PMX, to a control (PLC) or a
primary automation system.
Internal calculation channels
The PMX has 32 internal calculation channels as
standard, which are freely available for evaluations and
mathematical measurement signal calculations.
Automation tasks from peak values to PID controllers can
be implemented simply and elegantly.

PMX product description
The following types of plug-in card are available:
PX401
S The PX401 measurement card offers four individually
configurable current or voltage inputs with TEDS
sensor detection.
S Extreme accuracy is guaranteed, as all the channels
have their own A/D converter with 24-bit resolution.
This also allows the acquisition of all the channels to
be totally synchronized.
PX455
S The PX455 measurement card is available for
measurement with strain gages (SG) and also has
four channels with 24-bit resolution and TEDS sensor
detection.
S The measurement card is suitable for strain gages in
both half bridge and full bridge circuits, as well as for
inductive transducers in half bridge and full bridge
circuits, LVDTs, potentiometric sensors and PT100
resistance thermometers.
PX460
S The frequency measurement card PX460 can be used
to operate torque flanges (torque, speed, angle of
rotation), angle/incremental encoders, SSI/PWM
sensors and frequency measurements up to 2 MHz.
Channels 1 and 3: Frequency measurement (fixed)
Channels 2 and 4: Frequency (digital, inductive),
counter, encoder, SSI, PWM (adjustable)
PMX A4354-2.2 HBM: public 25
PMX product description
The following measurement modes are available:
- Up to four torque flanges (T10, T12, T40) for torque
or speed measurement (without direction of rotation
detection)
- Or two measuring channels for simultaneous
measurement of speed and angle (with direction of
rotation detection)
- Or one measuring channel for simultaneous speed,
angle and direction of rotation or reference pulse
detection
- Or two angle/incremental encoders each, SSI/PWM
sensors, magnetic transducers or pulse counters
- Or four measuring channels for frequency
measurement up to 2 MHz, incl. two shunt
calibrations and two 1-Wire TEDS (sensor
detection)
PX878
S The PX878 input/output card has a total of eight digital
inputs, eight digital outputs and five analog voltage
outputs. The PMX can be controlled by this or be
operated with a downstream controller (PLC). All real
or calculated measurement signals can be freely
assigned to the outputs.
PX01EC, PX01PN and PX01EP
S These interface cards can be optionally included in
the PMX, enabling operation of the PMX in an
automation system via the interface formats
EtherCat
, PROFINET or EtherNet/IP. Only one
variant can be used in each case.

PMX product description
Connection technique
Transducers are connected to the amplifiers via plug
terminals.
Plug terminals using push-in technology are available as
standard, with a screw-on system also available as an
option. If required, both types can be coded with the
enclosed coding pins to prevent mix-ups.
TEDS (Plug&Measure)
PMX amplifiers support TEDS (Transducer Electronic
Data Sheet, IEEE1451.4). When transducers are
connected, they are automatically detected. This
efficiently minimizes setup times and user error.
PMX web server
An easy to operate web server that is specifically tailored
to the PMX and is suitable for the measurement cards, is
integrated into the device for configuration, data
acquisition and visualization.
This gets you quickly to your measurement result, where
you can visualize the measured data and view them at a
later date.
PC software catman®EASY/AP
The HBM catman® software can be used to acquire,
condition and analyze the PMX measurement data, as an
option. This allows vast quantities of measurement data
to be displayed (stripchart function), analyzed and
exported in the most commonly used formats.
PMX A4354-2.2 HBM: public 27
PMX product description
Software driver
The PMX command set and a dotNET-API are available
to create customer-specific interfaces. This allows your
own operating concepts and the inclusion in existing
software solutions to be realized.
With the PMX-LabView driver, PMX can be integrated via
Virtual Instruments (VI) in the software of National
Instruments.
LabVIEW is a registered trademark of National
Instruments.
Device implementation
The multi-client capability of the PMX makes it possible to
access the device simultaneously and without loss of
speed via all the interfaces - including web server, field
bus and analog outputs.
Calibration certificates
Documented quality: at the time of delivery, PDF docu
ments of the HBM calibration certificates for the fitted
measurement cards, and a certificate of compliance as
per EN 10204 2.1 are already stored in the PMX device
memory. The PMX browser can be used to download
them.
