Isolated safety grid

The isolated safety gate adopts the circuit structure of electrical isolation between the input, output and power supply, and meets the requirements of intrinsically safe limited energy.

1. Due to the three-way isolation method, there is no need for the system grounding line, which brings great convenience to the design and site construction. Safety grid with distribution isolation.

2, the instrument requirements for the danger area 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 detection and control loop signal are greatly enhanced, thus improving the reliability of the entire system.

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

5, the isolated safety gate can output two mutually isolated signals to provide the use of 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.
