Top facts to know about the hybrid relay switching

What is the need for hybrid relay switching in the market?

Most of the people related to the electric field would have much in-depth knowledge about the two most significant types of relays which are

  1. EMR or electromechanical relay and
  2. SSR or solid-state relay

The ultimate comparison EMR Vs. SSR

Both electromechanical relay and the solid-state relay have merits and demerits on their side, but what’s more important is which among the two is best. Some people hold the bottom of SSR as it is more reliable as the electromechanical relay produces arcs and loses its reliability. On the other hand, some people say that SSR provides heat losses, and EMR is much more convenient and cheaper when compared with the SSR. The SSR also does not use any moving devices, which is the leading cause of its reliability. Both SSR and EMR can work either on AC or DC based on the situation.

The solid-state relay waste a lot of power as it drops down the voltage when the electric signals pass through the semiconductor channel. For example, the SSR can consume 15 watts or more than that for giving a 10 A of electrical load.

What are hybrid relay switching and its significant applications in the market?

By comparing the EMR and SSR, we conclude that both are good at some points and also hold an equal amount of negatives on the other. The best solution to make the best relay is creating a hybrid of EMR and SSR, which can offer both the features and hence increase the standard of the circuit.

To bring the right solution for all the problems, the Echola systems have brought PDUs types of relays, which make use of both electromechanical relay (EMR) and solid-state relay (SSR) and hence it successfully eliminates the cons of duo comprehensively.

The hybrid form of relay or PDU holds a parallel setup of the circuit of EMR and SSR. The SSR output switches the load when the signal is applied. On the other hand, the EMR establishes a parallel path for signal transport. Due to this operation, no-heat or small heat traces are produced in the SSR. As the SSR holds the initial load, the EMR does not have to transfer the entire amount, and hence the process can be completed in such a quick time.
