The P30U transducer from LUMEL is used to convert temperature, resistance, voltage and current standard signals to current and voltage and standard signals.
The output signal is galvanically isolated from the input signal and the power supply. The transducer has programmable measurement and auxiliary functions. Parameters can be programmed via buttons RS-485 interface (option) or via a PD14 programming device (option).
Universal input, programmable:
