ABB i-bus EIB / KNX General ® General Product and The analog actuator converts measuring data received via EIB / KNX functional overview telegrams into analog output signals. The analog output signals enable heating, ventilation and air conditioning units to adapt their output values to information received from the bus and thus to take part in control processes.
Device Technology ABB i-bus EIB / KNX ® Analogue Actuator AA/S 4.1 Device technology AA/S 4.1 The Analogue Actuator converts measured data received via the EIB / KNX to analogue output signals. The device features four outputs. The analogue outputs can be used as current or voltage outputs with adjustable out- put signals.

ABB i-bus EIB / KNX Commissioning ® Commissioning Application program 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.

ABB i-bus EIB / KNX Planning and application ® Planning and application Status displays After initial switch on the Analogue Actuator performs a scan (Status LED: “Orange / On”). As a new device is not pre-programmed in the factory, the Status LED subsequently switches to “Red / Flashes quickly”.

ABB i-bus EIB / KNX Planning and application ® Use of 16-bit values In the fewest of technical applications is the complete value range of the 2-byte floating point format actually fully utilised. At the same time there is a whole range of components which actually convert a general analogue variable such as voltage or current with their own conversion factor to different physical variables.

ABB i-bus EIB / KNX Planning and application ® The same conversion factor leads the actuator in the opposite direction for the “Status” communication object. The status object sends the new value with the following results: ¼ When the input value object receives a new value which differentiates from the current output value.
ABB i-bus EIB / KNX Planning and application ® Use of 8-bit values With the use of 8-bit values the parameters “Input value for 0 %”, “Input value for 100 %” and “Factor of the input value” are fixed and cannot be modified.
ABB i-bus EIB / KNX Planning and application ® Forced control Both in the 8-bit as well as the 16-bit mode every output features up to two 1-bit communication objects, which enable control with a higher priority. In order to use these objects the corresponding parameter must be set in the parameter “Forced control object …”.
ABB i-bus EIB / KNX Planning and application ® Cyclical monitoring In order to ensure that the control of an object does not fail, the actuator can implement timed monitoring of the input and/or forced control for each of its outputs. In 8-bit mode the communication objects “Switching” and “Dimming”...
