# SCHEMATIC SYMBOLS RELAY

readingratImage: readingratRelay Logic Circuits - Schematic/Symbols A relay logic circuit is a schematic diagram which shows various components,their connections,inputs as well as outputs in a particular fashion. In relay logic circuits,the contacts NO and NC are used to indicate Normally Open or Normally Close relay circuit.

A schematic usually omits all details that are not relevant to the key information the schematic is intended to convey,and may include oversimplified elements in order..Schematic - WikipediaSee all results for this questionWhat is pin 87A for?What is pin 87A for?After staring at some more diagrams,I think that the reason there are two 87pins(87 &87A) is because 87is set up for a circuit that is normally open(the contact rest on 87A) and 87A is set up for a circuit that is normally closed and when the cicuit/relay is energized it opens the contact.What is pin 87A for?(relay) - Ignition and ElectricalSee all results for this questionHow do relays work?How do relays work?How Relays Work. Relays work taking an electrical current through them. In response to this current,the coil of the relay produces a magnetic field. This magnetic field then attracts the mechanical switch,closing it.What is a Relay? - Learning about ElectronicsSee all results for this questionWhat is a relay used for?What is a relay used for?Relays are used to isolate one voltage level from another. A PLC may be used to control the operation of a medium-voltage motor,perhaps 2,300V or 4,160V. A relay is used to energize the starter,which,in turn,switches the motor voltage while the PLC controls the relay.The Basics of Control Relays | Electrical Construction &amp; MaintenancSee all results for this questionFeedback[PDF]

Reference designator - Wikipedia
The number is sometimes followed by a letter, indicating that components are grouped or matched with each other, e.g. R17A, R17B. IEEE 315 contains a list of Class Designation Letters to use for electrical and electronic assemblies. For example, the letter R is a reference prefix for the resistors of an assembly, C for capacitors, K for relays.
