The function of signal isolator：
Protect the subordinated control circuit.
The signal isolator can reduce the influence of environmental noise on the test circuit.
The signal isolator can suppress the interference of public grounding, frequency converter, solenoid valve and unknown pulse to the equipment. At the same time, it has pressure limiting and steady flow for the lower equipment. It is a transmitter instrument, a frequency converter, a solenoid valve, PLC /DCS input and output and a reliable communication interface. It can effectively isolate the input, output and power supply and the earth. It can overcome the frequency converter noise and various high and low frequency resonance interference.
