Relays continue to be useful and popular, but in low-power, battery operated applications they tend to be power wasters. The following relay economy circuits reduce coil power significantly by simply ...

An RC circuit in series with the coil allows full-current turn-on for reliable relay operation, then reduces the current to save power. Fellow engineer Sanjay R. Chendvankar of Mumbai, India, recently ...

The RYII series reflow-solderable miniature power PCB relay features one pole with 8A rated current and one CO, one NO or one NC contact. The device benefits from a low height of only 12.3mm, ...

Relays usually are driven using optocouplers, which offer isolation between analog and digital grounds to ensure that switching currents in the relay coils do not affect the noise margin of the ...

The new RC series of printed circuit board (PCB) relays replaces and upgrades the RJxV Series PCB-mount relays. RC Series relays are designed to mount directly to a PCB using through-holes and can be ...

Potential relays are commonly found on many smaller, single-phase, capacitor-start, capacitor-run motors in the HVACR industry. Their function is to assist in starting the electric motor. Potential ...
