relay logic system
1Relay logic — is a method of controlling industrial electronic circuits by using relays and contacts. ladder logic The schematic diagrams for relay logic circuits are often called line diagrams, because the inputs and outputs are essentially drawn in a series… …
2Relay — This article is about the electrical component. For other uses, see Relay (disambiguation). Automotive style miniature relay, dust cover is taken off A relay is an electrically operated switch. Many relays use an electromagnet to operate a… …
3Logic gate — A logic gate is an idealized or physical device implementing a Boolean function, that is, it performs a logical operation on one or more logic inputs and produces a single logic output. Depending on the context, the term may refer to an ideal… …
4Programmable logic controller — A programmable logic controller (PLC) or programmable controller is a digital computer used for automation of industrial processes, such as control of machinery on factory assembly lines. PLCs are used in many different industries and machines… …
5Digital protective relay — In electrical engineering of power systems, a digital protective relay uses a microcontroller with software based protection algorithms for the detection of electrical faults. Such relays are also termed as microprocessor type protective relays.… …
6Reed relay — A reed relay is one or more reed switches controlled by an electromagnet. The contacts are of magnetic material and the electromagnet acts directly on them without requiring an armature to move them. Sealed in a long, narrow glass tube, the… …
7Distributed operating system — A distributed operating system is the logical aggregation of operating system software over a collection of independent, networked, communicating, and spatially disseminated computational nodes.[1] Individual system nodes each hold a discrete… …
8Automotive navigation system — A taxi equipped with GPS navigation device An automotive navigation system is a satellite navigation system designed for use in automobiles. It typically uses a GPS navigation device to acquire position data to locate the user on a road in the… …
9Ladder logic — is a philosophy of drawing electrical logic schematics. It is now a graphical language very popular for programming Programmable Logic Controllers (PLCs). It was originally invented to describe logic made from relays. The name is based on the… …
10Wire spring relay — A wire spring relay is a type of relay, primarily manufactured by the Western Electric Company for use by the Bell System in electromechanical telephone exchanges. It was licenced for use around the world, and was commonplace in Japan. A wire… …
