Function
• The analog actuator module (extension module)
enlarges an KNX analog actuator by four analog
outputs which can be parameterized by means
of software.
• Received data are converted into the following
output signals: 0...1 V, 0...10 V, 0...20 mA or
4...20 mA.
• With these analog output signals, actuators
used for heating, ventilation and air conditioning
purposes are enabled to adapt their output
variables in acc. with informations received from
the bus and to be used within control processes.
• The output variables can be subject to forced
control.
• The module data as such and the forced-control
instructions are evaluated in the KNX analog
actuator
• The analog actuator module is connected to the
KNX device by means of a system connector
supplied with the device.
• Non used outputs can be deactivated.
• Voltage outputs are monitored for short-circuits.
• The output state is indicated by status LED.
Installation
The device is snap-fastened on a DIN rail 35 x 7,5
mm as per EN 50022.
G
The analog actuator module is connected to
an KNX analog actuator only by means of a
6-pole system connector (supplied with the
analog actuator module).

This unit can also supply the connected the
connected KNX analog actuator or other devices.
For easy connection, there are two pairs of internally
connected power supply terminals (marked by a
dot "•").
Connectable analog actuators
Safety warnings
• Do not connect electronic ballasts or
ç
electronic transformers with 1-10 V
control input to the outputs.
• Do not connect external voltages to the
outputs. Connected components must
ensure safe separation from other
voltages.
• The GND terminals must not be
connected with the terminals of the
same
designation
actuator (risk of irreparable damage!).
3
• Current outputs may be loaded with 500 Ω max.
• Voltage outputs must be loaded with 1 kΩ min.
• The GND terminals of outputs A1...A4 are
internally connected.
• In the event of a short-circuit between a voltage
output A1 ... A4 and GND, the respective output
is deactivated.

Installation of an analog actuator
module
During the installation of an analog actuator module
the following basic rules must be observed:
• An analog output module can be replaced by one
of the same type (e.g. in case of defect) while the
system is in operation (disconnect voltage supply
from module!). After the replacement, the analog
actuator makes a reset after abt. 25 s. This action
re-initializes all outputs of the analog actuator
and of the connected modules and resets them
to their original state.
• Removal or addition of modules without adapting
the project and subsequent downloading into the
analog actuator is not permitted as this will result
in system malfunctions.
