latching relay การใช้

• Magnetic latching relays can have either single or dual coils.
• Magnetic latching relays are useful in applications where interrupted power should not be able to transition the contacts.
• Such an electrically latching relay requires continuous power to maintain state, unlike magnetically latching relays or mechanically racheting relays.
• Such an electrically latching relay requires continuous power to maintain state, unlike magnetically latching relays or mechanically racheting relays.
• Some have a steel core, making them magnetically latching relays, similar to the ferreed and remreed types of reed relay.
• Coaxial electromechanical switches can be further divided into two categories based on their architecture, latching relay and non-latching relay.
• Coaxial electromechanical switches can be further divided into two categories based on their architecture, latching relay and non-latching relay.
• Very early computers often stored bits in a magnetically latching relay, such as ferreed or the later remreed in the 1ESS switch.
• Each magnetic latching relay had one transfer contact dedicated to sending a pulse back to the SD, on each operate and release.
• Stack lights are passive devices that may be controlled directly by programmable logic controllers, distributed control systems, sensors and latching relays.
• Magnetic latching relays require one pulse of coil power to move their contacts in one direction, and another, redirected pulse to move them back.
• In computer memories, latching relays and other relays were replaced by delay line memory, which in turn was replaced by a series of ever-faster and ever-smaller memory technologies.
• Such an electrically latching reed relay requires continuous power to maintain state, unlike magnetically latching relays, such as ferreed ( ferrite and reed relay ) or the later remreed ( remanent reed relay ).
• It typically has better thermal stability than a BJT . Because they are controlled by gate charge, once the gate is closed or opened, there is no additional power draw, as there would be with a bipolar junction transistor or with non-latching relays in some states.
• The computer controlled the magnetic latching relays by Signal Distributors ( SD ) packaged in the Universal Trunk frames, Junctor frames, or in Miscellaneous Trunk frames, according to which they were numbered as USD, JSD or MSD . SD were originally contact trees of 30-contact wire spring relays, each driven by a flipflop.
• The 219 packaged family of products, and the 219NE ( Nuclear Energy ) family, encompassed in addition to the standard electro-mechanical versions-the 236 / 237 / 238 family of industrial time-delay relays, the later 246 / 247 / 248 family of advanced time-delay relays, the 255 Series of latching relays, the 311 Series of Sequence / stepper relays, the 349 Series Voltage Sensors and the RSX Series of custom packages controls.
