Eaton Electromechanical Relays
Eaton electromechanical relays are used to switch electrical circuits on and off. They are typically used in industrial applications where a high degree of reliability is required.
Eaton electromechanical relays are designed to meet the needs of various applications, including power management, control systems, automation, and protection. They are available in a variety of types, including power relays, time-delay relays, and control relays.
One of the benefits of Eaton electromechanical relays is their durability. They are designed to withstand harsh environments and to operate reliably over a long period of time. They are also designed with features such as surge protection and noise suppression to prevent damage from electrical surges and interference.
Another advantage of Eaton electromechanical relays is their flexibility. They can be used in a wide range of applications and can be configured to meet specific needs. They are also available in a variety of mounting styles and terminal configurations, making them easy to install and integrate into existing systems.
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.
