When we think of relays, we tend to think of those big mechanical things that make a satisfying ‘click’ when activated. As nice as they are for relay-based computers, there are times when you don’t ...

Pickering Interfaces (Clacton-on-Sea, UK) has introduced the PI-MXT90-100 test tool that identifies faulty relays on its complex PXI switching matrices. The diagnostic tool uses a test adaptor and a ...

The 78 series 10-A relays are available with a variety of options, including a push-to-test button and a green LED status lamp. The ice-cube-style industrial relays use quick-connect, plug-in/solder ...

Tests of distance relay teleprotection schemes should check both relays simultaneously, including their communication link. This video shows a real test of a 110 kV overhead line. The protection was ...

The objective of protective relays and protective schemes is to protect electrical equipment such as transformers, lines, cables, bus bars, etc. during abnormal system conditions. Hence, protective ...

In this Design Idea, we look at how electromechanical relays display hysteresis behavior that is surprisingly similar to the solid-state Schmitt trigger circuits, and how they can be used for many ...

(MENAFN- GetNews) A relay module is a small electronic device that allows low-power signals to control high-power equipment. It works as a bridge between a control system-such as a PLC, Arduino, or ...

RF coaxial SPDT relays address signal-routing applications that demand a combination of high frequency, high power, and excellent RF performance. What role does an SPDT relay play in test applications ...
