Lumel-P30U
Universal transducer of temperature and standard signals with Ethernet

P30U transducer is designed to convert temperature, resistance, standard voltage and current signals into a standard DC voltage or DC current signal. The output signal is galvanically isolated from the input signal and the power supply. P30U has programmable measurement and additional functions.  Programming parameters can be realized with the use of buttons, via RS-485 interface and free e-con software or Ethernet or any web browsers via Ethernet interface.
