Solid State Relay Circuit Example

What is solid state relay.

Solid state relay circuit example. The electromagnetic force moves the armature. Solid state relay also known as ssr ss relay ssr relay or ssr switch is an integrated contactless electronic switch device that is compactly assembled from an integrated circuit ic and discrete components depending on the switching characteristics of the electronic components such as switching transistors bi directional thyristors and other semiconductor components the ssrs are able. Solid state relay is a type of switch to activate load by using without any mechanical parts. Solid state relay optocoupler relay.

Construction operation applications types of ssr relays. Solid state relay ssr circuit using mosfets last updated on june 21 2020 by swagatam 46 comments ssr or solid state relays are high power electrical switches that work without involving mechanical contacts instead they use solid state semiconductors like mosfets for switching an electrical load. In this article we will briefly discuss the ssr solid state relay its construction operation schematics different types of ssr relays based on its switching property and input output forms we will also discuss the advantages disadvantages of solid state relay ssr comparing to electromagnetic. There are many circumstances in which we need to control a high current voltage load based on the operation of a low power circuit such as when using the 5v output of a microcontroller to turn on a 10a 240v load.

Solid state relays ssrs representative example of switching for ac loads. This article provides an introduction to the basic operation of solid state relays with a focus on the output devices in today s ssrs. The armature switches the contacts in synchronization. The most common application of solid state relays is in the switching of an ac load whether that is to control the ac power for on off switching light dimming motor speed control or other such applications where power control is needed these ac loads can be easily controlled with a low current dc voltage using a solid state relay providing long life and high switching speeds.
