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 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 ...

The safety-monitoring relay will go into a fault state and not re-energize until someone corrects or fixes the fault at the contact of the affected MPCE. If a safety control circuit must carry a high ...

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 ...

Module provides enhanced Safety Category 1, 3, and 4 functionalities, with microcomputer-based diagnostics bringing IoT connectivity to industrial safety applications. DC Velocity Staff ...

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, ...

Achieve max electric fuel pump output and safety using a relay plus an oil pressure safety switch. Achieving maximum output and safety with a custom-wired electric fuel pump requires a properly ...

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.

Over the years, control relays of various types have been used by the hundreds — even thousands — to control nearly every function in commercial and industrial processes. Today, many of those ...

Safety is a major concern in a good many motor-driven applications. This is true in industrial applications where motion starts when power is applied and especially true when power is restored after ...

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 ...
