Product and functional overview
The Analogue Actuator has four or two analog outputs, which can be defined as voltage or current outputs
(not applicable to AA/A) and can be parameterized in one of the following formats using software. Outputs
that are not required can be deactivated.
In the process, various signal outputs are pre-configured to react (respond) in a particular way.
Voltage signals:
Output
0...1 V
0...5 V
0...10 V
1...10 V
Current signals (not applicable to AA/A):
Output
0...20 mA
4...20 mA
The output variables can be forcibly operated by a higher-level control system.
In addition, specific processes can be predefined for the outputs using the function Characteristic.
Each channel can be assigned up to 16 scenes.
Note
Analogue Actuator AA/S requires an external 100...240 V AC 50/60 Hz power supply.
Analogue Actuator AA/A requires no auxiliary voltage.
