1. the fence does not require special safety grounding, easy to use security gate wiring diagram;
2. the complete isolation of the input/output signal fence, making equipment more secure and reliable work;
3. fence signal completely floating, greatly enhanced signals in the system anti-interference ability;
4. fence easy to implement signal;
5. the separation security fence does not need grounding, wide adaptability;
6. isolation safety barrier is high frequency as a fundamental, signal modulation and demodulation, and signal a change, accuracy will suffer the effects of safety gate circuit;
7. the separation barrier due to its high frequency oscillatory circuits will produce radio-frequency interference, detrimental to the system and the isolation safety barrier is relatively easy to damage
