After we understand the working principle of the signal isolator, we should understand what its functions are, then what are the functions of the signal isolator? Today's signal isolator manufacturers to give you a brief introduction.

Function of signal isolator:

First, protect the lower control loop.

Second, reduce the impact of environmental noise on the test circuit.

3. Prevent interference of common ground, frequency converter, solenoid valve and unknown pulse to equipment; At the same time, the subordinate equipment has the function of limiting pressure and current, which is the faithful protection of transmitter, instrument, frequency converter, solenoid valve PLC/DCS input and output and communication interface. DIN series rail structure, easy to install, can reasonably isolate the input, output and power supply and the potential between the ground. It can overcome the frequency converter noise and various high and low frequency pulsation interference.
