ACT20X signal converters
The ACT20X is a completely new line of signal converter
products for the Ex zone. These compact modules require
only 11 mm per channel and take up very little space in
the electrical cabinet. Weidmüller has specifically designed
the ACT20X line for process automation applications in Ex
and non-Ex zones. The 17 different variants can process all
standard input signals (such as 2-wire, HART®-, NAMUR-,
RTD, thermocouple or DC signals) from Ex zone 0. They
can also handle digital or analogue signals from Ex-zone
field devices to the controller. The integrated relay output
issues an alert in the event of a malfunction; this makes
troubleshooting easier and reduces facility down times.
The WI-Manager configuration software is based on FDT
(Field Device Tool) technology. The software allows you to
configure all ACT20X products with your PC so that they
can be custom-fit to a wide variety of process applications.
Weidmüller provides a device type manager (DTM) for
the ACT20X modules that can be used in any FDT-based
frame. The DTMs allow you to configure different devices
quickly and accurately. They also enable you to analyse
measurements and diagnostics data. The DTM can also be
used to clearly identify the connected device. The FDT frame
application “WI Manager“ and the device-specific DTMs
are available from Weidmüller free of charge. The ACT20X
modules can be used in a temperature range from –20 °C
to +60 °C without limitations. The modules can be installed
in the safe zone or in the explosion risk area of Zone 2. The
ACT20Xs always deliver a pure, interference-free signal
B
B.2
thanks to their accuracy, temperature stability and high
insulation strength. They can easily be used around the
globe since they already have all the necessary international
approvals, including ATEX, ICEEX, GOST and FM.
The newest member of the ACT20X family is the ACT20XHUI-SAO-LP. This offers an intrinsically safe input for 0/4 to
20 mA, 0 to10 V, temperature and resistance signals, and
separates the Ex zone from the safe zone. The narrow
12.5 mm module is supplied via the 4 to 20 mA output.
Features
•International approvals for Zone 0, 1 and 2 (IECEx, ATEX)
and Class 1 Division 1 and 2 (FM)
•Analogue and binary signal interface to Zone 0/Div.1 for
explosion-risk inputs and outputs
•All standard input signals (4 to 20 mA HART®-, NAMUR-,
RTD- or thermocouple signals) out of Ex zone 0, 1 or 2
•Two-channel type saves space in the electrical cabinet
and reduces installation costs
•HART® transparent signal isolator
• Integrated alarm contact
•Configuration over FDT/DTM standard with the frame
application “WI Manager“

ACT20X meets the arduous requirements of the process
industry where potentially explosive fluids are controlled. The
range connects to sensors and actuators in the hazardous
area, isolates their signals and limits the energy passed to
them. On the input side ACT20X models can process d.c.,
B.4
temperature, Namur and volt-free contact signals. On the
output side field devices in the Ex area are controlled via
the ACT20X with analogue or digital signals. All ACT20X
products are characterised by insulation, accuracy and high
temperature stability.
The digital 2-channel versions with width of 22.5 mm
are available with either transistor or relay output. Due to
this high component density, the space requirements and
installation costs are reduced accordingly.

Worldwide application
Fulfils the strict standards and requirements of the process industry. Can be
used worldwide due to international and
local approvals ATEX, IECEX,
CULUS, FM, GOST and DNV.
Intelligent connection system
Pluggable, coded, with release lever.
The release lever simplifies
maintenance and allows disconnection
without damaging the cables.
Alarm function
No laborious troubleshooting. Alarm
function integrated for cable or sensor
errors. In case of failures, a diagnostic
signal is sent to the control system.
