Last column, I wrote about various applications where fire alarm relays could be used to integrate a commercial fire alarm system with other electrical systems at a customer’s site to provide them ...

LG5924 Series relays are single-channel E-stop relays designed to protect people and machines in applications with emergency stop buttons. Available with 24 VDC, 110 VAC, and 230 VAC coil voltages, ...

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.

When it comes to electronics, it seems like a relay is such a simple device – yet, it is able to interface some pretty elaborate high-end systems with a fire alarm system. Working with relays is an ...

If you've ever wondered how electronic devices manage to control circuits with precision and safety, you're thinking about the magic of relays. Relays act as the unsung heroes in many of our devices, ...

Equipped with two release-current paths and one signal-current path and with reinforced insulation separating the paths, the PSR safety relays are said to provide reliable protection for any and all ...

The PSR-FSP2/2x1 and PSR-FSP/2x1 process safety relays are safe interposing relays specifically designed to operate with fail-safe controls in process applications. The PSR-FSP/2x1 can be used in ...

Factory equipment continues to become increasingly intelligent in large part due to the improved processing power and communication abilities found within underlying controllers, sensors, and ...

The six safety vital relays developed by Clearsy France are the very first self-controlled safety vital relays guaranteeing opening of their NO contacts at a SIL4 level. Since 2016, these safety vital ...

Featuring three contacts per alarm input, the SRM Safety Relay Module from Moore Industries enables alarm contacts to be integrated into safety processes without having to rely on a specialized form ...

Panasonic has unveiled, what it claims, is the world’s smallest 2 pole safety relay with power contacts on both normally-open and normally-closed sides. The device measures just 33 x 14.0mm by 7.8mm ...
