6.3 I/O MAP address in the Radioline wireless
system
Figure 3 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.
6.4 Network applications (operating mode)
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).
Only the RAD-AO4-IFS module can be assigned to the
RAD-PT100-4-IFS module.
The Pt100 inputs, T1...T4, can be configured to the analog
outputs I1/U1...I4/U4 of the RAD-AO4-IFS extension mod-
ule.
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
only appear once in the network.

6.5 Display and diagnostic elements
The I/O extension module uses a total of three LEDs to indi-
cate the operating states.
Figure 4 Display and diagnostic elements
6.6 Temperature input (Pt100)
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.

6.7 Assembly/removal
Figure 6 Mounting and removing
When using the device in a connection station, use the
17.5 mm wide DIN rail connector supplied. Only use the DIN
rail connector in connection with 24 V DC devices.
•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.
•You can establish a connection between two DIN rail
connectors using MINI COMBICON connectors:
MC 1,5/5-ST-3,81 (female, 1803604);
IMC 1,5/5-ST-3,81 (male, 1857919).
6.8 Connecting the cables

6.9 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.
Figure 8 2-wire connection technology
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 RLat 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.

4-wire connection method
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.
