Analogue relay with current input PA-01I
The PA-01I device is used to convert the analog signal 0÷20 mA/ /4÷20 mA to the signal controlling the relay output. This allows the use of sensors with an analogue output in automation systems.
Functioning
The PA-01I device continuously measures the current 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 also possible to connect PA-01I in series with other 4÷20 mA receivers. PA-01I can operate in four different modes selected by the FUNC knob.
