FAQs

What is correct relay dimensioning?

Correct relay dimensioning refers to the process of selecting a relay with the appropriate specifications and capabilities to meet the requirements of a specific application. It involves considering various factors and parameters to ensure that the relay can handle the desired load, voltage, current, and environmental conditions effectively.

Relays: Electromechanical vs Solid State

Electromechanical Relays

Electromechanical relays (EMR) use physical moving parts to achieve the desired functionality. These moving parts include the contacts that switch between the normally open and normally closed stationary contacts in the relay. This movement is made possible by an electromagnet. When power is applied to this magnet, it will act on the movable contact causing the relay to switch. In an EMR, it is common to hear the switching sound that is represented as a “clicking” noise. This audible noise can be helpful when determining the functionality of the relay. 

Solid State Relays

Solid state relays (SSR) use a low power, electrical signal to generate an optical semiconductor signal that will transmit and energize an output signal. When this is activated, the input optical signal will act as the switch, allowing a higher voltage signal to pass through the relays output components. The internal circuitry of a SSR is far more complex than an EMR, but there are no physical moving parts.
