  • Introduction
  • Specifications
Products description
It is a miniature cartridge converter.It convert the signal of  voltage（mV or V）、current（mA） into the proportional output signal of with the isolation of 1～5VDC or 4～20mADC.
It is an intelligent transmitter,calculating with microprocessor.
You can choose two kinds of powers(AC ,DC power),it has output signal (1～5VDC or 4～20mADC) selsct and disconnection protection.It can also switch between many indexing Numbers.(except for input signal of power).
