Isolated safety grid and Zener safety grid

Compared with Zener safety grid, although the price is higher, many of its advantages and characteristics still bring users a lot of convenience, so that more and more users prefer to choose isolated safety grid.

② The use of isolated safety grid can effectively isolate the field loop signal in the danger area and the safe zone loop signal. In this way, the intrinsic safety automatic control system does not need the intrinsic safety grounding system, which simplifies the construction of the application of the intrinsic safety explosion-proof system.

The use of isolated safety grid greatly enhances the anti-interference ability of the detection and control loop and improves the reliability of the system.

④ Use isolated safety grating to allow the field instrument to be grounded and allow the field instrument to be non-isolated.

The isolated safety grid has many protective function circuits, the possibility of accidental damage is less, allowing on-site instrument live maintenance, which can shorten the project start preparation time and reduce parking time.

⑥ Isolated safety grid has strong signal processing capability. Such as switching input status control, mV, Pt100 into 4 ~ 20mA and so on. In this way, the application of field instrumentation and control system provides greater convenience, rationality and effectiveness.

7 When the user applies DCS and ESD at the same time, the selection of a two-in safety gate can effectively isolate the two systems and avoid mutual influence between the systems.

The loop power supply isolated safety gate not only maintains the advantages of active isolated safety gate, but also has the convenient wiring like Zener safety gate, does not need another 24V power supply, especially suitable for DCS system with I/O card direct power supply.
