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.

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, ...

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 ...

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 ...

When it comes to choosing the right safety relay, identifying the smallest performance improvements can result in big productivity gains. That’s why SICK has developed its ReLy safety relays to ...

Power systems today operate in an environment where reliability and safety must be maintained despite rising loads, expanding ...

Insulation resistance testers, often called megohmmeters, are fundamental tools for preventive maintenance, used to assess ...

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 ...

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 ...

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 ...
