  • Page 5: Application

    1. APPLICATION The P30U programmable transducer is designed to convert temperature, resistance, direct voltage and direct current signals into a standard DC voltage or DC current signal. The output signal is galva- nically isolated from the input signal and power supply. The transducer is fitted with a 2x8 LCD screen.
