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 ...

Abstract: Sneak circuit analysis is a vital component of circuit reliability assessment. However, conventional methods for sneak circuit analysis are unsuitable for relay circuits. In this paper, we ...

A single-coil latching relay is a relay with memory, usually with a magnetic structure that provides two stable positions for the armature that holds the movable contacts. A permanent magnet provides ...

Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...

In a not yet dim past we started this series with an ‘energy-efficient relay’. Here is a variation on that topic, and a super-simple one at that. The big disadvantage of the energy-efficient relay ...

Some control applications are too small or simple to use even the smallest PLC, but still need more flexibility than a simple relay. That's why engineers at Schneider Electric, Palatine, Ill.

[Alex] was tasked with a control design problem for a set of motors. The application called for the back of a truck to open up, some 3D scanning equipment to rise from its enclosure, and finally the ...

An overcurrent relay is a protective device that detects excessive current flow and triggers circuit breakers to prevent damage. Commonly used in power systems, it safeguards equipment from faults, ...
