Safety grating is an energy limiting circuit between the field equipment and the control room equipment. It is used to limit the electric energy supplied by the control room to the field instrument. It can neither produce enough sparks to detonate dangerous gases nor generate enough surface temperature to detonate dangerous gases, thus eliminating the source of detonation. When choosing safety grate, we must consider the compatibility between safety grate and intrinsic safety instrument and the impedance matching in intrinsic safety system.
Safety grating function: that is, safety retainer, or safety limiter, which is mainly used in intrinsic safety system, has a great role. It can transfer dangerous signals and plays an indispensable role in related industries. Next, we will introduce the product information about safety grids: safety grids are the safety interface in the safety circuit, which can let the signal be transmitted in the safety zone and dangerous zone, and guide the signal transmission, usually installed in the intrinsic safety circuit or non-intrinsic safety circuit. The so-called intrinsically safe explosion-proof system mainly refers to the equipment installed in a safe place and connected between intrinsically safe and non-intrinsically safe electrical equipment. Safety grid occupies a very important position in intrinsic safety system, and its performance is very good. Because the safety grate is mainly designed between the field equipment and the control room equipment, no matter what state the equipment in the control room is in, even in the failure state, it can ensure that the signal transmitted is safe.
Isolated safety grille is the most common type of safety grille. Its design and fabrication can meet the requirements of intrinsic safety system. Although this kind of safety grille is more expensive than Zener type safety grille, its performance is very good, and it can bring many benefits to users.
Isolated safety grids not only prevent dangerous energy from intrinsically safe terminals into dangerous sites, but also improve the intrinsically safe explosion-proof performance of the system, and increase the anti-interference ability of the system, which greatly improves the reliability of the system operation. After the 24 VDC power supply is converted by DC-AC-DC, it can output various voltages required by the module circuit.
