3 Function
System information
This device is a product of the KNX system and complies with the KNX directives. Detailed
technical knowledge obtained in KNX training courses is a prerequisite to proper understanding.
The function of this device depends upon the software. Detailed information on loadable software and attainable functionality as well as the software itself can be obtained from the
manufacturer´s product database. Planning, installation and commissioning of the device are
carried out with the aid of KNX-certified software. The latest versions of product database and
the technical descriptions are available on our website.
Intended use
- The 4-off analog input processes measuring data from analog sensors. Up to four freely
combinable analog measurement transducers can be connected.

4 Information for electrically skilled persons
4.1 Mounting and electrical connection
Mounting a 4-off analog input
o Mount the device on a DIN rail with the KNX connection facing downwards.
i An analog input module is only connected to the analog input with the 6-pin system con-
nector (enclosed with the analog input module).
i Use an NEC Class 2 suitable power supply unit AC 24 V SELV for power supply.

o Connect device as shown in the connection example (figure 2).
o Connect bus line with device connection terminal.
i Use only cables which are approved for KNX.
i Observe the cable routing! The connection cable must not come into prolonged contact
with elements conducting heat, e.g., a heating pipe or radiator.
Supply of connected sensors
i Connected sensors can be supplied via the terminals +Us and GND of the analog input
module (figure 2). These are provided double and are internally connected with each other
in each case.
i The total power consumption of all sensors supplied in this way must not exceed 100 mA.
i In the case of overload or short-circuit between +Us and GND, the voltage is switched off.
After the fault has been corrected, the voltage automatically switches on again.
Installation of the analog input module
When an analog input module is installed, the following basic rules must be observed:
o A maximum of one analog input module can be connected.
o An analog input module can be replaced with one of the same type, e.g., in the case of a
fault, while the system is running (de-energize the module!). After replacement, the 4-off
analog input will perform a reset after approx. 25 seconds. As a result, all inputs and outputs of the 4-off analog input and the connected modules will be re-initialized and reset to
their original state.
i It is not permitted to remove or add modules without adapting the project design and sub-
sequently downloading to the 4-off analog input, since this leads to malfunctioning of the
system.
4.2 Commissioning
Programming the physical address and application program
o Switch on the external supply voltage.
o Switch on the bus voltage.
o Assign the physical address and note it on the device label.
o Program the application program.
i No programming is possible if no mains voltage is connected.
