All You Need to Know About SSRs

Their acronym SSR popularly knows solid state relays. They are used to switch loads on AC and DC circuits in a large number of electrical gadgets. The job of solid state relays is similar to the part played by electromagnetic switches. But there are some vital differences between these two. An electrical, as well as a mechanical engineer, must know about these points of distinction.

What are the Things to Know Before Learning SSR?

Getting the hang of the basics

It is also vital to understand which of these should be used in a specific scenario. A solid-state relay becomes crucial when voltage is applied on a device externally. Semiconductors play a vital part in the proper operation of solid state relays. Switching of currents will not be possible in the absence of high-quality conductors.

Speed is essential

Switching between loads becomes quick and easy when a machine has robust state relay technology. An electromagnetic relay never has the same rate of operation that its solid-state counterpart can provide. So, engineers prefer the use of solid state relays when the size of the machine is not substantial, and the operation needs to be done quickly.

EMRs are useful too

When pieces of equipment use a lot of power, opting for electromagnetic relays will be the better option. Solid state relays cannot endure currents higher than a hundred amperes. So, the arrival of SSRs has not obliterated the use of electromagnetic relays, but it has carved out a niche for itself.

Solid state relays are more dependable

Solid state relays do not have any visible wear and tear even after they are used for prolonged periods. If you choose a solid-state relay for switching loads in a machine, you can rest assured that very little maintenance will be needed. On the other hand, the resistance posed by magnetic switches is substantial. You will need to be ready for repairs at regular intervals.

Why has the popularity of EMRs decreased?

Electromagnetic relays are bulky, and they take up a lot of power to operate correctly. Hence, the operational cost of electromechanical relays is more than solid state relays. As already stated, solid state relays function swiftly, and they make very little noise when they are at it. It is because of these qualities that a large number of mechanical as well as electrical engineers have started using solid state relays in recent years. It is highly probable that this trend is here to stay.
