LZN1000 Series

The LZN1000 Series two-wire input temperature transmitter is a high performance device that receives Thermocouple / RTD / W / mV input and output mA with HART communication protocol.
Three internal keys to set parameter. Zero span calibration can be achieved either by HART or keypad.
