Precautions for Installing Isolation Intrinsic Safe Barriers The isolation intrinsic safety barrier is a device that is used in intrinsically safe explosion-proof systems to safely isolate field instruments. For explosion-proof systems and explosion-proof elect... More+
The Role of Intrinsic Safe Barriers and the Four Advantages of Isolated Barriers Ⅰ. What is the role of intrinsic safety barriers?The intrinsic safety barrier is an energy-limiting circuit between the field equipment and the control room equipment, which is used to limit the elec... More+
The Formation and Harm of Lightning Lightning disaster occurs frequently in summer, which belongs to a kind of meteorological disaster and is one of the ten most serious natural disasters recognized in the world. Lightning can cause cas... More+
Classification and Measures for Lightning Protection in Buildings 1. Classification of lightning protection in buildingsAccording to the importance of the building, the nature of use, the possibility of lightning accidents and the consequences, as well as the requir... More+
The Role and Function of Safety Relay Ⅰ. The monitoring function of the safety relay on the input signalAll safety designs have dual-channel safety conditions. The existence of these safety conditions determines the state of the safety o... More+
Six Precautions for Safe Use of Intrinsically Safe Barriers The intrinsically safe barrier will transmit the voltage and current signals from the dangerous area to safe areas through isolation and transmission to output a single-channel or mutually independent... More+
The Difference Between Safety Relays and General Relays In today's era of advanced industrial technology, we often use safety relays when connecting electronic appliances in order to ensure the safety of the entire line, so how do we distinguish betwee... More+
How to Select the Signal Isolator? In addition to determining the function of the isolator and adapting to the front and rear end interfaces, there are many parameters such as accuracy, output ripple, temperature drift, power consumpti... More+
The Role of Safety Relay Contacts The "safety relay" is not a "no-fault relay", but a regular action in the event of a fault. It has a forced guide contact structure to ensure safety in case of a fused contact, whi... More+
The Principle of Surge Protective Device Surge protective device (SPD for short), also known as surge protector, lightning protection grid, lightning surge protector, lightning arrester, etc., is the device for limiting transient overvoltage... More+
Distinguish Signal SPD and Power SPD from the Principle and Application of Surge Protector Surge protection device, referred to as SPD, is a device that limits transient overvoltage and discharge surge current. It can divert the lightning surge current into the ground and protect the instru... More+
