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 ...

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

Weidmuller is proud to introduce a new line of long life single-phase and three-phase Power Solid-State Relays (PSSR). These relays are designed to reliably switch AC loads up to 20 Amps, making them ...

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 ...

Here’s a MEMS relay with an integrated FET that can handle higher power levels, breaking away from the “low power” moniker associated with MEMS parts. Paul Rako takes a closer look at what makes this ...

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 ...
