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 ...

Abstract: Electromechanical relay logic including overcurrent and distance relay logic.Electronic logic circuits including analog and digital logic circuits.Analog relay logic for a variety of relays ...

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 ...

Relays usually are driven using optocouplers, which offer isolation between analog and digital grounds to ensure that switching currents in the relay coils do not affect the noise margin of the ...

Hybrid relays combine a mechanical switch with a solid-state switch, and they are set up in parallel to control a single load ...

[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 ...
