توضیحات
رله ي 5 پايه ي 30 ولت 3 امپر
رِله (به انگليسي: Relay)، نوعي کليد الکتريکي است که با فرمان يک مدار الکتريکي ديگر باز و بسته مي‌شود.روش کنترل باز و بسته شدن اين کليد الکتريکي به صورتهاي مختلف مکانيکي، حرارتي، مغناطيسي، الکتروستاتيک است. رله را ژوزف هانري در سال1835ميلادي اختراع کرد.
از آنجا که رله مي‌تواند جرياني قوي‌تر از جريان مدار فرمان خود را هدايت کند، به معني وسيع‌تر مي‌توان آن را نوعي تقويت کننده نيز دانست که در زمان قديم براي تقويت سيگنال هم به کار مي‌رفت.
در گذشته رله‌ها معمولاً داراي سيم‌پيچ بودند و از جريان الکتريکي براي توليد ميدان مغناطيسي و باز و بسته کردن مدار سود مي‌بردند.
Description
relay LZL-60-C LZL60C 60VDC 60V DC60V 5PIN
A relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid-state relays. Relays are used where it is necessary to control a circuit by a separate low-power signal, or where several circuits must be controlled by one signal. The first relays were used in long distance telegraph circuits as amplifiers: they repeated the signal coming in from one circuit and re-transmitted it on another circuit. Relays were used extensively in telephone exchanges and early computers to perform logical operations.
A type of relay that can handle the high power required to directly control an electric motor or other loads is called a contactor. Solid-state relays control power circuits with no moving parts, instead using a semiconductor device to perform switching. Relays with calibrated operating characteristics and sometimes multiple operating coils are used to protect electrical circuits from overload or faults; in modern electric power systems these functions are performed by digital instruments still called "protective 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. Repeated pulses from the same input have no effect. Magnetic latching relays are useful in applications where interrupted power should not affect the circuits that the relay is controlling.
