PHG-11TH/PHG-12TH
Overview
The potentiometer input signal isolator can isolate and convert the potentiometer signal into a DC signal output. The conversion circuit sends the 2.5V voltage to the input potentiometer, and the potentiometer then transmits the partial pressure back to the circuit.
This product needs to be powered independently, and the power
supply, input and output terminals are isolated.
