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 ...

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 ...

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 ...

Specifically designed to operate with fail-safe controls in process applications, the PSR-FSP process safety relay can be used in applications up to a Safety Integrity Level (SIL) 3 requirement, ...

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 ...

Programmable logic controllers (PLCs) and computer-based controllers are great for handling logic and data-collection tasks for industrial controls. But when it comes to driving motors, heaters, ...

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 ...

Potential relays are commonly found on many smaller, single-phase, capacitor-start, capacitor-run motors in the HVACR industry. Their function is to assist in starting the electric motor. Potential ...
