The Analogue Actuator is used to convert physical values (2 Byte) or
relative values (1 Byte) to analogue voltages (0 ... 1 V, 0 ... 10 V) or currents
(0 ... 20 mA, 4 ... 20 mA). In this manner for example, components for
cooling and air conditioning system such as valve drives for ventilation flaps
or other devices can be integrated into the EIB / KNX system.
The outputs are deactivated ("no function") in the default setting. The
required voltage or current signal can be selected separately with the
"Signal Output X" parameter. As soon as the output is activated the ETS
indicates further parameters and communication objects. An active output
features the communication object "Input value" and a communication
object "Status", and even further parameter communication objects which
are dependent on its parameters.
Both the parameter pages "Output X 1/2" and "Output X 2/2" belong to
every active output. The required input format (16 bit or 8 bit) and the
behaviour after a reset are defined on the first of both parameter pages.
8-bit values can be used by a large number of EIB / KNX devices. They
feature a limited resolution. 16-bit values feature a high resolution and
ensure very flexible adaption to the respective system functions. However,
they require more initial effort when setting the parameters.
The second parameter page enables the use of forced control objects
with higher priorities, time monitoring of the input objects and setting of a
dimming function using relative values (1-byte object).
