A single-coil latching relay is a relay with memory, usually with a magnetic structure that provides two stable positions for the armature that holds the movable contacts. A permanent magnet provides ...

Over the years, control relays of various types have been used by the hundreds — even thousands — to control nearly every function in commercial and industrial processes. Today, many of those ...

Latching relays change their states when you apply a short voltage pulse to their coils. Because these relays require no continuous coil currents to keep their states, you can save considerable power ...

Recently, [Manuel] did a post on making logic gates out of anything. He mentioned a site about relay logic. While it is true that you can build logic gates using switch logic (that is, two switches in ...

Same Sky’s Relays Group has announced the addition of new latching power relay models to its power relays product line. The PRL family of latching power relays features single coil and double coil ...

Same Sky has introduced a family of latching power relays with single or double coils, and 10 to 20A ratings. PRL relays, as they will be known, have silver alloy contacts and come in SPST (1 Form A), ...

The latching DW relay from Panasonic has been developed for smart meters, in particular the switching of heater circuit-breakers. Available from TTI, the relays can also be used to minimise standby ...

Large scale digital logic began not with the vacuum tube but the electromechanical relay. Although vacuum tubes were available at the time – and were used on competing machines – Konrad Zuse chose to ...

Many varieties of ON/OFF control circuits use some form of flip-flop that responds to a pushbutton switch or other control input. These all have volatile memory and default to an OFF condition if ...
