Safety regulations and installation
notes
Observe the following safety notes when us-
ing the device.
WARNING: Risk of electric shock
–
Provide a switch/circuit breaker close to
the device, which is labeled as the dis-
connect device for this device or the en-
tire control cabinet.
•
•
The category 3 device is suitable for installation in po-
tentially explosive area zone 2. It fulfills the require-
ments of EN 60079-0:2012 and EN 60079-15:2010.
–
–
Provide overcurrent protection (I ≤ 6 A) in
Installation, operation, and maintenance may only be
carried out by qualified electricians. Follow the installa-
tion instructions as described. When installing and op-
erating the device, the applicable regulations and safety
directives (including national safety directives), as well
as general technical regulations, must be observed. For
the safety technology data, see this packing slip and the
certificates (EC examination certificate and other ap-
provals if appropriate).
With the exception of configuration of the thumb wheel,
opening or modifying the device is not permitted. Do not
repair the device yourself; replace it with an equivalent
device. Repairs may only be performed by the manu-
facturer. The manufacturer is not liable for harm result-
ing from noncompliance.
the installation.
Disconnect the device from all power
sources during maintenance work and
configuration (the device can remain con-
nected to SELV or PELV circuits).
–
The housing of the device provides a ba-
sic insulation against the neighboring de-
vices, for 300 V eff. If several devices are
installed next to each other, this has to be
taken into account, and additional insula-
tion has to be installed if necessary. If the
neighboring device is equipped with ba-
sic insulation, no additional insulation is
necessary.
•
•
•
The IP20 protection (IEC 60529/EN 60529) of the de-
vice is intended for use in a clean and dry environment.
The device must not be subject to mechanical strain
and/or thermal loads, which exceed the limits de-
scribed.
To protect the device against mechanical or electrical
damage, install it in a suitable housing with appropriate
degree of protection as per IEC 60529.
•
•
The device is not designed for use in atmospheres with
a danger of dust explosions.
If dust is present, it is necessary to install into a suitable
approved housing, whereby the surface temperature of
the housing must be taken into consideration.

Safety regulations for installation in potentially
explosive areas
WARNING: Explosion hazard when used
in potentially explosive areas
Please make sure that the following notes and
instructions are observed.
•
Observe the specified conditions for use in potentially
explosive areas! Install the device in a suitable ap-
proved housing with a minimum of IP54 protection) that
meets the requirements of EN 60079-15. Observe the
requirements of EN 60079-14.
•
•
In zone 2, only connect devices to the supply and signal
circuits that are suitable for operation in the Ex zone 2
and the conditions at the installation location.
In potentially explosive areas, terminals may only be
snapped onto or off the DIN rail connector and wires
may only be connected or disconnected when the pow-
er is switched off.
•
•
The switches of the device that can be accessed may
only be actuated when the power supply to the device is
disconnected.
The device must be stopped and immediately removed
from the Ex area if it is damaged, was subject to an im-
permissible load, stored incorrectly or if it malfunctions.

You can set the network application of the wireless module
with the PSI-CONF software. All RAD-2400-IFS Radioline
wireless modules are set to I/O data mode (wire in/wire out)
by default.
Radioline wireless module in I/O data mode
The input device must be provided with the same I/O MAP
address as the assigned output device at the other Radio-
line wireless station (I/O mapping).

Thumb wheel
Use the thumbwheel to set the I/O-MAP address. The exten-
sion module in the Radioline wireless system is addressed
using the I/O-MAP address.
On the entire wireless network, addresses 1 to 99 (I/O MAP)
(maximum) may be assigned for the I/O extension modules.
Radioline wireless module in PLC/Modbus RTU mode
The I/O MAP address of an input module may only appear
once in the network.
The input data is saved in a Modbus memory map in the
Radioline master wireless module.
You can read or write the process data via the serial inter-
face of the RAD-2400-IFS master wireless module
(RAD-ID = 01) using the Modbus RTU command
(see Section 7).
The I/O MAP address of an input module may

Temperature input (Pt 100)
The I/O extension module uses a total of three LEDs to indi-
cate the operating states.
The Pt 100 inputs of the extension module can process tem-
peratures from -50 °C ... +250 °C.
All the inputs are electrically isolated from one another, from
the supply voltage (via bus foot), and from other electronic
components.
Pt 100 resistance thermometers can be connected to the
RAD-PT100-4-IFS I/O extension module. The thermome-
ters change their resistance depending on the temperature.
The Pt 100 input signals are acquired by the RAD-PT100-4-
IFS and can be mapped to proportional, analog voltage or
current signals of the RAD-AO4-IFS output module. Thus,
conclusions can be made about the temperature via the
standard analog signal.

Outside the Ex area, module extension or
module replacement is also possible during
operation.

•
Connect the DIN rail connectors together for a connec-
tion station.
Push the connected DIN rail connectors into the DIN
rail.
Place the device onto the DIN rail from above. Ensure
the device and DIN rail connector are aligned correctly.
Holding the device by the housing cover, carefully push
the device towards the mounting surface so that the de-
vice bus connector is securely fixed onto the DIN rail
connector.
•
Once the snap-on foot has been audibly snapped onto
the DIN rail, check that it is fixed securely. The device is
only mechanically secured via the DIN rail.
•
•
•
Connect the desired number of I/O extension modules
to the wireless module via the DIN rail connector.
Install the device in suitable housing to meet the re-
quirements for the protection class.
During startup, check that the device is operating,
wired, and marked correctly.

Connecting the sensors
You can connect 2-wire or 3-wire sensors to the extension
module. Take into account the measuring errors depending
on the different measuring methods.
2-wire connection method
With 2-wire technology, you need an insertion bridge be-
tween terminals x.2 and x.3.
For short distances (< 10 m).
•
•
Connect the Pt 100 sensor to terminals x.1 and x.3.
Bridge the terminals x.2 and x.3.
2-wire connection technology is the most cost-effective con-
nection method. The temperature-related voltage is not di-
rectly measured at the sensor and is therefore falsified by
the two cable resistances. The measuring errors that occur
may render the entire measurement useless.
Cable resistances RL1 and RL2 are incorpo-
rated in the measurement result directly and
falsify the result accordingly.

3-wire connection method
For long distances between the Pt 100 sensor and the ex-
tension module. To compensate the wire resistances, all
wire resistances must have exactly the same values (RL1
RL2 = RL3).
=
•
Connect the Pt 100 sensor to terminals x.1, x.2, and x.3.
With 3-wire connection technology, the temperature-related
voltage is measured several times. Corresponding calcula-
tions additionally reduce the effect of the cable resistance on
the measurement result. The results are almost as good as
those achieved using 4-wire technology.
The cable resistances RL at terminals +I and -I must have
the same value. This allows you to subtract the established
cable resistance from the measurement result and to get the
Pt 100 platinum resistance value.

The extension module does not support 4-wire connection
technology.
•
If you want to use a 4-wire sensor, only connect three of
the four wires.
•
The fourth wire should be left unwired. Otherwise there
will be a different resistance in the +I and -I cables owing
to the parallel connection of two cable resistances.
