Rail mounting device, 4 rail units ETS product family: Output Product type: Analogue output 4-gang The analogue output needs 24 V AC for operation. The necessary power can be supplied by the power supply unit ref.-no.:WSSV10. The analogue output converts measuring data received via KNX telegrams (DPT-ID 9.0xx and 5.010) into analogue output signals. The analogue 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.Voltage signals: 0 ... 1 V DC 0 ... 10 V DCCurrent signals: 0 ... 20 mA DC 4 ... 20 mA DC The analogue output offers four analog outputs which can be software-parameterised for one of the ranges mentioned above. Outputs not used can be deactivated. The output variables can be force-controlled from a coordinating control system. With an analogue output extension module, the number of analog outputs canbe increased from 4 to 8. In conjunction with the dimming function of a sensor, both, the analogue output and also the analogue output extension module can be used as an active control unit for dimming applications. Remarks on the hardware: The GND terminals must not be connected to the corresponding terminals of another device. The outputs of the analogue output and of the analogue output extension module must not be connected to the 1 ... 10 V interface of electronic ballasts or electronic transformers. All connected components must ensure safe separation from other voltages
