This chapter covers representative general-purpose relays used in the control circuits of most industrial, commercial, and consumer products. Relay names and terminology are in accordance with ...

A motor protection relay safeguards electric motors by detecting thermal stress, phase imbalance, stall, and abnormal ...

How many remote controls do you have in your home? Don’t you wish all these things were better integrated somehow, or that you could add remote control functionality to a random device? It’s a common ...

Level control is used in applications where fluid is being moved, monitored, or otherwise included in the system. Crouzet level control relays work by taking input from two level sensors, such as ...

No matter what the application is, when a definite-purpose solution is required, time delay relays (TDRs) can provide simple, reliable, and economical control. Adjusting the delay time is often as ...

When voltage sags occur inside or outside of a facility, properly placed power quality mitigation technology will save sensitive equipment from costly shutdowns. The cost of this mitigation equipment ...

AutomationDirect has added new motor control, phase monitor, alternating, pump seal, and intrinsically safe relays to its collection of relays. ProSense motor control relays from AutomationDirect ...

An electrical relay is a type of heavy-duty, remote-control switch able to handle high-current accessories, yet capable of being actuated by substantially less current. Relays install between the ...

Members can download this article in PDF format. In this design idea, you will learn how to interface two PIC microcontrollers using a wireless 433-MHz RF transmitter/receiver pair to control up to ...
