Eaton Solid State Relays

More Information about Eaton Solid State Relays

One of the benefits of Eaton SSRs is their precise control. They can switch on and off very quickly and with high accuracy, making them ideal for applications where precise control of voltage and current is required. They also produce less electrical noise than mechanical relays, which can reduce interference and improve system performance.

Another advantage of Eaton SSRs is their durability. They have no moving parts, which means they are less likely to fail due to wear and tear. They are also designed to withstand harsh environments, with features such as surge protection and thermal management to protect against electrical surges and overheating.

Eaton SSRs are designed to meet or exceed industry standards for safety and performance. They are tested to ensure they can withstand extreme temperatures, humidity, and other environmental factors, and are certified to meet various international standards, such as UL, CSA, and CE.

Relays: Electromechanical vs Solid State

Electromechanical relays (EMR)

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 (SSR)

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.
