Functioning
The PA-01U device continuously measures the voltage signal connected to the input terminals (7-9) and on the basis of the measured value and the selected operating mode decides about the switch-on of the executive relay. The measuring input is galvanically isolated from the power supply of the device and the contacts, thanks to which it is possible to measure the voltage within the range of 0÷10 V in a circuit independent of the supply voltage of the device. PA-01u can operate in four different modes selected by the FUNC knob.
Analogue relay with voltage input PA-01U
The PA-01U device is used to convert the analog signal 0÷10 V to the signal controlling the relay output. This allows the use of sensors with an analogue output in automation systems.
