When to use mechanical vs. solid-state devices. The parameters that should be considered when selecting a device. Optimize your selection for lowest cost/maximum ...

Manufacturers of switches and relays have faced several big challenges over the past few years. OEMs, particularly in higher-reliability markets, continue to look for greater flexibility and ...

A relay module is an electrical component. Various industries use this circuit board that houses one or more electric switches or relays in different circuits and electrical projects. Relay boards are ...

The reed relay was invented in 1936 by Bell Telephone Laboratories. Since that time, it has gradually evolved from very large, relatively crude parts to the small, ultra-reliable parts we have today.

Impulse relay is a viable alternative for lighting control from multiple locations. In modernistic houses and apartments, lighting schemes to control lights from two or more locations are becoming ...

Omron has announced mosfet opto-relays that can switch 3.3Aac or 6.6Adc, giving them the highest-ever current carrying capacity, said the firm. Mosfet relays use light to isolate the primary side, ...

Pickering has created a high voltage reed relay, that can stand off 1.5kV and switch up to 1kV. Called Series 131, they are single pole (normally-open) single-in-like devices with a 12.5 x 3.7mm ...

Inspired by input from panel builders, system integrators and end users around the world, Rockwell Automation engineers developed the new Allen-Bradley E300 electronic overload relay. The E300 ...

Relays and contactors use a variety of technologies to switch signals and power connections. Many devices called relays use similar techniques and topologies, but the terminology can be confusing.
