23/01/27Dhyana 401D iyo FL20-BW waxay adeegsadaan qaab kicinaya iyada oo loo marayo wareegga go'doonsan ee optocoupler - halbeeg warshadeed oo si ballaaran loo isticmaalo si looga sooco qalabka elektiroonigga ah ee saxda ah ee kamaradda lagana saaro koronto kasta oo dibadda ah ama faragelin. Shuruudaha wareegyada kicinta go'doonsan ee indhaha indhaha ayaa xoogaa ka duwan kuwa heerka TTL ee loo isticmaalo kamaradaha kale.
Optocoupler lafteedu waa qayb adag oo ka kooban diode iftiin leh (LED), iyo transistor sawir-qaade ah, kaas oo u shaqeeya sida beddelka. Marka kamaradu rabto inay soo saarto calaamada kiciya, qadar yar oo iftiin ah ayaa laga soo diraa LED-ka oo loo diro transistor-ka iftiinka-xasaasi ah, ka dibna u oggolaanaya hadda inuu dhex socdo. Laakin labada wareeg ayaa gabi ahaanba ka go'doonsan midba midka kale, taasoo la micno ah in kamaradu ay ka ilaaliso faragelin kasta oo koronto ah oo kaga timaada aaladda dibadda. Sidoo kale, gelinta kiciyeyaasha waxay dhaqaajiyaan muraayadaha indhaha si ay calaamadahooda ugu gudbiyaan kamarada.
Tusaalekicinta habaynta ee wareegyada kicinta ee go'doomiyey indhaha. Sanduuqa buluuga ah ee dahaaran ayaa muujinaya qalabka dibadda ee kamarada. Xariiqda lagu calaamadiyay 'TRIGGER OUT' waa pin-kicinta kaamirada. Wareegtan oo dhan ayaa lagu soo celiyaa marka ay noqoto biinanka Kiciyeyaasha badan. Isha danab ee VCC2 iyo iska caabiyaha R3 waa in lagu daraa isticmaaluhu.
Si ka duwan TTL kiciyeyaasha halka isku xirka kamaradku uu si toos ah u xakameyn karo danabka loo soo diro fiilada kiciya, tusaale ahaan u dirida calaamadda sare ee 5V qalab dibadda ah, wareegyada go'doonsan ee optokoupler waxay u dhaqmaan si ka badan sida beddelka, kaliya xakamaynta in wareeg dhamaystiran la sameeyay iyo in kale. Danabka ku jira wareeggaas waa in lagu dejiyaa (sidoo kale loo yaqaan 'la soo jiiday') dibadda iyada oo loo marayo resistor. Ugu dambeyntii si loo abuuro wareegga dhamaystiran wareegga kicinta waa in lagu xidhaa dhulka - kamaradu waxay leedahay pin 'Kiciyaha Ground' oo lagu muujiyay qaybta jaantusyada Pin-Out ee hoose oo ay tahay in lagu xiro dhulka korontada.
Sida ku cad jaantuska sare, waa in lagu daraa isha danab ee VCC2 iyo resistor R3. Danabka lagu taliyay waa 5V – 24V, taas oo ku xidhan hadba korantada uu filaayo kicinta ku xidhan qalabkaaga dibadda, inkasta oo inta badan aaladaha tani ay noqon karto 5V. Iska caabiyaha R3 ayaa go'aamiya hadda socda ee wareegga, iyo caabbinta lagu taliyey waa 1KΩ.
Dejinta kicinta
Marka kamaradu rabto inay soo saarto calaamada kicinta, wareegga indhaha waa xiran yahay oo hadda wuu qulquli karaa, iyo Aaladda Dibadda ayaa diiwaangelin doonta isbeddelka tamarta.
