1. Because of the three-way isolation method, no system grounding line is required, which brings great convenience to the design and site construction.

2. The requirements for instruments in dangerous areas are greatly reduced, and there is no need to use isolated instruments on site.

3. Because the signal line does not need a common ground, the stability and anti-interference ability of the signal of the detection and control loop are greatly enhanced, thus improving the reliability of the entire system.

4. The isolated safety gate has a stronger input signal processing ability, and can accept and process thermocouples, thermal resistance, frequency and other signals, which is not possible with Zener safety gate.

5. The isolated safety gate can output two mutually isolated signals to provide two devices using the same signal source, and ensure that the signals of the two devices do not interfere with each other, while improving the electrical safety insulation performance between the connected devices.
