Methods of Creating Lightning Induced Surges and Lightning Protection Systems May 09 , 2023 Lightning induced surges There are three main coupling methods: 1) resistive coupling, 2) inductive coupling, and 3) capacitive coupling. Resistive coupling When lightning strikes the air terminal of ...

What is a Signal Isolator? Apr 08 , 2023 Definition of Signal IsolatorA signal isolator, also known as an isolator, signal converter or signal conditioner, is an important component of industrial control systems. A signal isolator is an elec...

Conversion Work of Temperature Transmitter and Its Advantages Apr 01 , 2023 How does the temp transmitter perform conversion work?Temp transmitters convert physical measurement signals or ordinary electrical signals into standard electrical signal for output or devices that c...

Distinguish Signal SPD and Power SPD from the Principle and Application of Surge Protector Mar 31 , 2023 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...

The Principle of Surge Protective Device Mar 23 , 2023 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...

How to Select the Signal Isolator? Feb 23 , 2023 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...

The Difference Between Safety Relays and General Relays Feb 16 , 2023 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...

The Role of Safety Relay Contacts Feb 09 , 2023 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...

The Role and Function of Safety Relay Jan 18 , 2023 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...

Six Precautions for Safe Use of Intrinsically Safe Barriers Jan 11 , 2023 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...
