Load-powered latching relay architecture enables battery-free HVAC control designs while reducing system complexity, size, ...

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 ...

Operating from a 24-Vdc isolated power supply, the devices use an input control from 4 to 20 mA or 0 to 10 Vdc. Features of the relays include an integral heat sink for controlled cooling, DIN-rail ...

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 ...

Relays and solenoids are available with many different voltage ratings. Most factory- and process-automation equipment operates from 24-V supplies. However, customers may have control signals for a ...

Designers often use relays as electrically controlled switches. Unlike transistors, their switch contacts are electrically isolated from the control input. However, the power dissipation in a relay ...

Automotive electronic control applications require robust input power conditioning. The circuitry must absorb 100-V transients on one hand, while providing a stable dc bus for a few hundred ...
