Signal isolators, smart digital display meters, and multi-function meters are commonly used devices in the field of industrial automation, and they each have different characteristics and uses. This article will introduce their principles, functions, and application scenarios separately so that readers can better understand the role of these devices in industrial automation.
1. Signal isolator.
Signal isolator is a device used to isolate input signals, which can effectively reduce the impact of external interference on the signal and improve the stability and reliability of the signal. Signal isolators usually use the principles of photoelectric isolation, magnetic isolation or capacitive isolation, and select the appropriate isolation method according to different application scenarios.
The role of signal isolator is mainly manifested in the following aspects:
1.Strong anti-interference ability: By isolating the input signal, it can effectively avoid the influence of external noise and interference on the signal, and improve the purity and stability of the signal.
2.Protect the safety of the equipment: The signal isolator can play a role in protecting the subsequent equipment from damage caused by abnormal signals or overvoltages.
3.Scalability: Signal isolators usually have multiple channels, and multiple input signals can be connected as needed, making it easy to expand and maintain.
In practical applications, signal isolators are widely used in various industrial automation equipment and systems, such as sensors, actuators, PLCs, etc., which provide a strong guarantee for the stable operation of equipment.
