Relay mai Tsawo: Me ke wani? (Shaida na Kukunshi Da Yadda Ya Samu)
Wani shine Latching Relay?
Latching relay (ko da ake kira bistable, keep, impulse, stay relay, ko kuma “latch” na baya) ita ce mai tsari biyu na switch na electromechanical. Ita ce switch na shiga kasa wanda ake amfani da ita don tabbatar da matsayin tare da ba ake yi shiga kasa ba.
Latching relay ana amfani da ita don kontrola hanyoyi masu yawan kasa da kasa guda. Coil na latching relay yana amfani da kasa ne bayan an kawo ON. Sannan contact ta zai baki a matsayin bayan an kawo OFF. Tabbata diagram na latching relay tare da cikakken bayani game da tare da wannan ya faru.
Latching relay tana dace da double-throw toggle switch. A cikin toggle switch, idan an saka trigger a matsayin tare, za a baki a matsayin tare har zuwa idan an saka trigger a matsayin tare mafi yawa.
Duk da haka, idan an set electrically a matsayin tare, latching relay za a baki a matsayin tare har zuwa idan an reset a matsayin tare mafi yawa.
Latching relay tana kira impulse relay, bi-stable relay, ko kuma stay relay.
Wani shine Impulse Relay?
Impulse relay tana daya daga cikin latching relay kuma ana kiran ta a kai bistable relay. Ana amfani da ita don rubuta hanyoyi masu pulse.
Idan impulse relay yana kawo, ita ce ya haɗa da matsayin tare, kuma yana kawo coil na musamman. Sannan relay za a baki a matsayin tare har zuwa idan a kawo OFF.
Idan a kawo kasa, contact yana yin hanyar da ita kuma za a baki a matsayin tare. Kuma wannan yanayi tana faru a kan ON/OFF kasa.
Wannan type na relay tana da muhimmanci a cikin abubuwan da ake amfani da su kamar ON/OFF devices daga wurare da push-button ko momentary switch. Misali, ana amfani da ita a cikin circuit na lighting ko conveyer don kontrola daga wurare.
Latching Relay Circuit Diagram
Circuit na latching relay tana da biyu na pushbuttons. Button-1 (B1) tana amfani da ita don faɗa circuits, kuma Button-2 (B2) tana amfani da ita don kawo OFF circuit.
Idan B1 tana saka, coil na relay za a kawo. Sannan za a kawo contact A to B da C to D.
Bayan an kawo coil na relay da kuma kawo contact A to B, supply tana ci gaba a kan bayan an kawo OFF B1.
Za a kawo OFF coil na relay don kawo OFF circuit. Saboda haka, don kawo OFF coil na relay, muna saka B2.
Yadda Latching Relay Ya Faru?
B1 tana NO (Normally Open), kuma B2 tana NC (Normally Closed). Saboda haka, a lokacin farkon, B1 tana buƙaci, kuma B2 tana kawo.
An saka B1 don kawo ON circuit. Bayan an saka B1, current tana ɗaukar (+Ve)-B1-A-B-(-Ve).
Wannan tana kawo coil na relay. Contact A tana kawo B da C tana kawo D.
Idan kana kawo B1, coil na relay za a baki a kawo, kuma current tana ci gaba a kan circuit. Hanyar current tana (+Ve)-B2-B-A-(-Ve).
Don kawo OFF circuit, muna kawo OFF coil na relay. Don haka, muna kawo OFF hanyar current.
An amfani da B2 don kawo OFF circuit. B2 tana NC. Saboda haka, idan kana saka button, tana ƙirƙira a matsayin buƙaci. Saboda haka, idan kana saka B2, tana kawo OFF hanyar current.
Ana iya kawo relays daga birane daga wurare da contacts.
Yadda a Yi Latching Relay Circuit
A nan, a ke nufin yadda a yi latching relay circuit kafin kafin.
Step-1 Kawo Relay da push-button da DC supply kamar yadda aka nufin a cikin figure tare.
Push-button tana Normally an Open (NO) switch. Saboda haka, a lokacin farkon, switch tana buƙaci. Idan kana saka push button, relay tana kawo. Sannan idan kana kawo, relay tana kawo OFF.
Wannan tana daidaita a kan relay da push-button. A cikin latching relay, relay tana baki a matsayin kawo har zuwa idan kana saka push button.
Step-2 Saboda haka, don latching relay, common point na relay tana kawo a kan source via push button, kamar yadda aka nufin a cikin figure tare.
