An introduction to signal relays

Signal relays are widely used to control the flow of electrical current in a variety of applications ranging from simple household appliances to complex industrial systems.

Thanks to their straightforward design, they are an ideal choice for safely and reliably controlling circuits from a distance. Because signal relays are typically used to switch current of 2 A or less at voltage ratings between 5 and 30 Vdc, they are often referred to as “low signal relays.”

“An Introduction to Signal Relays” from the CUI Insights blog explains the basic operation and specifications of signal relays in greater detail. It also highlights the differences between signal relays, power relays, and solid state relays, while providing guidance on how to select the right signal relay and exploring their typical applications.
