Communication enabled signal converter ACT20C product brochure

More transparency in your process automation
Status monitoring via Ethernet with the ACT20C
Let’s connect.
Analogue signal conditioning
Your process requires the utmost attention
Our new ACT20C signal conditioners support you in achieving this
Many process parameters in your system are handled by your
control system, which shows you the current status of your
process. Even so, do you have a full overview of critical
system states? And this at all times, at every location, and
with the recent system history?
With the ACT20C, you receive accurate information on the
status of the sensors, signal processing and cabling. Data can
be called up and will depending on your individual
communications infrastructure. This comprehensive overview
allows you to accurately analyse errors and faults, and initiate
targeted actions taken by system operators and maintenance
personnel. By doing so, this technology contributes to
ensuring reliable system operation.
ACT20C signal conditioner with Ethernet interface
Comprehensive process transparency is provided
by the transfer of diagnostics information, signals and data
You would like more process transparency for your
systems. We support you with signal conditioners
that supply you with precise information via our
Ethernet interace. Let’s connect.
To be able to control systems and processes optimally, you
require a constant flow of information on the current states
of individual applications, devices and functions.
Our ACT20C signal conditioner not only monitors the signal
conversion, but also communicates precise information
on device status, signals and data directly to connected
computer and control systems.
Our Ethernet interface enables an event-controlled transfer
of diagnostics information, which in turn supports the
elimination of faults in, for example,
plant operation.
Universal signal conversion
Can be used in a multitude of
applications thanks to customer
and application specific defined
conversion methods with just one
single module.

existing Ethernet networks.
Detailed analysis and presentation of core process parameters
The ACT20C supplies key parameters and historical data,
independent of the location
Thanks to the ACT20C, Weidmüller is now the first to offer
a solution which supplies you with extensive diagnostic
and status information without the need to deal with the
complexity of field bus systems.
the front panel or via the Ethernet, and performance is
ensured through the manufacturer-independent FDT/DTM
software platform. To work with this platform, Weidmüller
provides the WI-Manager universal FDT frame application.
The isolating converters are based on the proven, robust
technology of transferring analogue signals to the DCS
system. Various signal sources and field devices can be
connected to the input side of the isolating converters.
As a result of this, the ACT20C can be configured for the
user-defined processing of current, voltage and transmitter
signals. Access is accomplished via a service interface on
Data collected in the ACT20C is made available over
the Ethernet via Modbus TCP. Depending on the
communications infrastructure, you can make this data
available to your SCADA system within your network, and
you can also access it via the Internet from any location
using an industrial Ethernet router.
