ABB KSD211B

Description

ABB KSD211B is a coupler module,which is usually used in industrial automation control systems and power electronics.The following is a detailed analysis of ABB KSD211B:

1.Product Overview

Name:ABB KSD211B Coupler Module

Application scenario:As a key component of power input,this module is often used in industrial automation,control systems,power electronics and other fields.

2.Technical Features

Function:It can realize the coupling and transmission of power supply signals,ensure the stable input of power supply,and provide necessary electrical isolation and protection functions.

Working principle:The power signal is added to the input end of the photocoupler to make the light source emit light,and the intensity of light depends on the magnitude of the excitation current.After this light is irradiated on the packaged photoreceiver,a photocurrent is generated due to the photoelectric effect,which is led out from the output end of the photoreceiver,thus realizing the conversion of electricity-light-electricity.

Components:KSD211B photocoupler is mainly composed of three parts,including light emission,light reception and signal amplification.

Light emission:It is mainly composed of light-emitting devices,generally light-emitting diodes.When a forward voltage is applied to a light-emitting diode,it can convert electrical energy into light energy and emit light,and can be driven by DC,AC,pulse and other power sources.

Light reception:mainly composed of photosensitive devices,generally photosensitive transistors.Photosensitive transistors work by using the principle that when a reverse voltage is applied to a PN junction,the reverse resistance changes from large to small under light irradiation.

Signal amplification:mainly composed of electronic circuits,etc.
