The relay repeater module accepts single contact closure inputs from logic solver trip outputs including the company's STA Safety Trip Alarm and the SPA2 Programmable Limit Alarm Trip. With three ...

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 ...

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.

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 ...

What is a relay? What is zero voltage switching? How to create a zero-crossing relay driver with a simple external circuit. A relay is a device that allows for a smaller electronic switch to control a ...

As automation expands, mechanical functions are relying more and more on electronic control. Solenoids provide an electromechanical interface for many of these applications. In addition, many ...
