Signal Isolator, Loop Powered, 4-20mA/0-20mA/0-5V/0-10V

5 out of 5 based on 4 reviews | Write a review
$122.13
Analog signal isolator is composed of pluggable PCB power board and separable isolating circuit module. It can be input the loop powered sensor signal or the external powered sensor signal by the selector switch. Signal isolator is suitable for industrial field with severe signal interference. Signal isolator adopts digital calibration, automatic zero calibration, DIN rail installation way and no potentiometer, with strong input/output/power supply isolation, fast response, low-power dissipation, and good anti-interference performance.

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.

Analog signal isolator can be input both loop powered signal and external powered signal
The input signals of this analog signal isolator can be both loop powered signal and external powered signal. It's very powerful. In this case, I won't worry about buying a wrong one. And when installing in the site, it also saves the works of changing the lead wires and changing the PLC program. It's so great!

4-20mA signal isolator with high accuracy
We use the FLUKE725 process calibrator to calibrate ATO 4-20mA signal isolator. When the calibrator displays a standard output of 12 mA, fine adjusting potentiometer for calibration. After finishing the calibration, the accuracy of full range is better than 0.1%, and the linearity is better than 0.1%. It is great!

Analog signal isolator is good for solving interference problem.
The analog signal isolator is easy to use. I don't need to confirm whether to buy a loop powered isolator or external powered isolator, because it has both modes. I can use the switch to select the one I need. After measurement, the isolator accuracy is indeed very high and the stability is good. I'm so glad that the system's interference problem is solved. I hope to cooperate with you for a long time.
