A relay is an electrically operated switch.Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid state relays.Relays are used where it is necessary to control a circuit by a separate low power signal, or where several circuits must be controlled by one signal.Mercury relay
A mercury relay (mercury displacement relay, mercury contactor) is a relay that uses mercury as the switching element.. They are used as high current switches or contactors, where contact erosion from constant cycling would be a problem for conventional relay contacts.. Owing to environmental considerations about the toxicity of mercury, mercury relays are mostly obsolete though modern ...Suggested Electric Fan Wiring Diagrams
SPST vs SPDT Relays. What’s the difference? Single Pole, Single Throw (SPST): This relay will be identified as having a middle 87b spade (or no middle spade at all).This is the most common relay used for fog lights or other simple circuits.QSK for the TL 922 and SB 220 With Circuit Improvements ...
High Speed Switching QSK for the TL 922 and SB 220 With Circuit Improvements for the TL 922 by Richard L. Measures, AG6K. HSS Diagram available at Figure 7B.. updated 27 JANUARY, 2011Configuring a Cisco Router as a Frame Relay Switch
The Cisco Frame Relay switching feature can be used to support a Frame Relay network using only routers. Consider the example in Figure 4 5 in which two Cisco routers are configured as Frame Relay switches implementing a Network to Network Interface (NNI) between them.Solid State Relay (SSR); H Bridge, Selection Guide ...

Electrical Relay Contact Types. As well as the standard descriptions of Normally Open, (NO) and Normally Closed, (NC) used to describe how the relays contacts are connected, relay contact arrangements can also be classed by their actions.Electrical relays can be made up of one or more individual switch contacts with each “contact” being referred to as a “pole”.Cisco Frame Relay Configurations > Configuring Frame Relay
Chapter Description Jonathan Chin dicussess basic Frame Relay operations on Cisco routers in a router based Frame Relay network. He also explains how to configure a basic frame relay network involving Cisco equipment and how to perform basic monitoring and troubleshooting using relevant Cisco IOS show and debug commands.Working of Relays How Relay works,Basics,Design ...
Relay Working. In this article, the basics of a relay like energized relay and de energized relay are explained in detail. Also, the design, construction, working, applications, and also relay selection is explained in detail.Relay definition of relay by The Free Dictionary
