    Tips: What is external powered signal isolator and loop powered signal isolator?

    1. External powered signal isolator
      It need an independent DC 20-35V switching power supply. The signal isolator samples 4-wire current signal and outputs 4-wire current signal after isolation. The advantage of this approach is high accuracy of isolation transmission. Power, input and output are completely isolated. Multi channel system power supply does not need isolation, thus ensuring a high anti-interference performance. The input signal can be converted to other types of signal.
    2. Loop powered signal isolator
      In the actual industrial monitoring system, DCS, PLC or other display instruments adopt cards internal power supply, the cards have higher requirement on the signal isolation transmission accuracy, so does the distribution voltage of a 2-wire transmitter. However, the external powered isolator can't meet these conditions. Therefore, the loop powered isolator is selected. Such a signal isolator provides working power supply to the 2-wire transmitter and samples the 2-wire current signal output by the transmitter. It converts the 2-wire current signal to 4-wire current signal after isolation and then output. In this way, it not only retains the superior performance of the external powered signal isolator, but also meets the requirements of the output loop powered interface.
    Existing reviews of Signal Isolator, Loop Powered, 4-20mA/0-20mA/0-5V/0-10V
    Signal isolator for VFDs
    Signal isolator is specially used to manage all kinds of off-brand VFDs. As long as using the loop powered signal isolator, the VFD is not subject to any interference, and the working state is very stable.
