2 PMX product description
By buying the PMX measuring amplifier system, you have chosen a high-qu-
ality HBM measurement system that is compact, powerful and variable. The
data rate for all the measurement and computing channels is 19,200 meas-
urements per second. The device thus achieves an overall calculating rate of
approx. 400,000 measured values per second.
A vast number of different measurement and control 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 in-
puts/outputs, as well as over the fieldbus interfaces of the PMX, to a control
(PLC) or a primary automation system.
Internal computing channels
The PMX has 32 internal computing channels as standard, which are freely
available for evaluations and mathematical measurement signal calculations.
Automation tasks from peak values to PID control can be implemented simply
and elegantly.
The following types of plug-in card are available:
PX401
The PX401 measurement card has four individually configurable current or
voltage inputs.
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
The PX455 measurement card is available for measurement with strain
gauges (SG), and also has four channels with 24-bit resolution.
The measurement card is suitable for strain gauges in both half bridge and
full bridge circuits, as well as for inductive transducers in half bridge and full
bridge circuits, LVDTs and potentiometric sensors.

12 Product description
A3257−2.0 en/de/fr
PX878
The PX878 input/output card has a total of eight digital inputs, eight di-
gital outputs and five analog voltage outputs. The PMX can be con-
trolled by this, as well as operated with a downstream control (PLC). All
real or calculated measurement signals can be freely assigned to the out-
puts.
PX01EC and PX01PN
These interface cards can be optionally included in the PMX, enabling
operation of the PMX in an automation system via the interface formats
EtherCator ProfiNet. Only one variant can be used in each case.
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). When the
PMX is activated, it automatically detects whether sensor with TEDS is
connected. The data are read out and the amplifier channel is parameterized
accordingly. This efficiently minimizes setup times and user error.
When the transducer is replaced in the activated state, the new TEDS is also
detected automatically but has to be activated manually.
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 configura-
tion, data acquisition and visualization.
This gets you quickly to your measurement result, and you can visualize the
measured data, subsequently view them and export them in the most com-
monly used formats.
