Qalabka NPN iyo PNP iyo Siemens PLC Connection and Selection

Dareemayaasha waxaa loo kala saari karaa laba nooc oo waaweyn iyadoo lagu salaynayo noocyadooda wax soo saarka: NPN (sidoo kale loo yaqaan isha - nooca dareemayaasha) iyo PNP (sidoo kale loo yaqaan saqafka - nooca dareemayaasha). Labada nooc ee dareemayaasha waxay leeyihiin saddex hoggaan, kuwaas oo ku xiran 24V, 0V, iyo Out (signal saarka). Haddaba, waa maxay noocyada dareemayaasha ay taageerayaan taxanaha Siemens S7 PLCs?

Noocyada Sensors ee ay taageeraan Siemens PLCs iyo Modules

Dareemayaasha ay taageerayaan Siemens S7-200: Mawduucyada wax gelinta ee taxanaha S7 - 200 waxay taageeraan labada il - nooca iyo saxanka - nooca dareemayaasha, taasoo la macno ah inay ku xidhmi karaan midkood NPN ama dareemayaasha PNP.

Dareemayaasha ay taageerayaan Siemens S7 - 200smart: Si la mid ah S7 - 200, S7 - 200smart's input terminals waxay taageerayaan saqafka - nooca iyo isha - nooca dareemayaasha, taas oo u oggolaanaysa isku xirka dareemayaasha NPN iyo PNP labadaba.

Dareemayaasha ay taageerayaan Siemens S7-1200: S7 - 1200's input terminals waxay taageerayaan dareeraha-nooca iyo isha - nooca, taas oo awood u siinaysa isku xirka NPN ama PNP labadaba.

Dareemayaasha ay taageerayaan Siemens S7 - 300 : S7 - 300 waxay leedahay noocyo kala duwan oo DI ah, iyo nooca dareemayaasha ay taageerayaan waxay u baahan yihiin in lagu hubiyo qaabeynta qalabka iyadoo lagu saleynayo xuduudaha.

Inta badan qaybaha DI ee S7 - 300 waa nooca-nuugista (Dareemaha PNP waa in la doortaa): Qaabaynta qalabka, ma jirto wax degdeg ah oo loogu talagalay nooca isha ama nooca waaskada, taas oo macnaheedu yahay inay yihiin kuwo ku habboon nooca. Tusaale ahaan, moduleka 321-1BL00.

Isha - nooca DI modules ee S7 - 300 (Dareemaha NPN waa in la doortaa): Tusaale ahaan, moduleka 6ES7 321 - 1BH50 - 0AA0.

Qaybaha Universal DI ee taageera labada nooc ee isha iyo biyaha (labadaba dareemayaasha NPN iyo PNP waa la isticmaali karaa): Tusaale ahaan, moduleka 6ES7 321 - 1BP00 - 0AA0.

Dareemayaasha ay taageerayaan Siemens S7 - 1500 : Qaybaha DI ee hadda laga heli karo taxanaha S7 - 1500 waxaa ka mid ah nuucyada nuucyada nuska ah ee taageera dareemayaasha PNP iyo isha - nooca modules ee taageera dareemayaasha NPN.

Sink - nooca DI modules (Dareemada PNP): Tusaale ahaan, moduleka 6ES7 523 - 1BL00 - 0AA0.

Hababka Xadhkaha ee NPN iyo PNP Sensors

Fahamka Noocyada Gelitaanka Gelitaanka ee PLC-yada: Qeexitaannada isha - nooca iyo nooca - nooca ee Siemens PLC terminal gelinta waxay ku saleysan yihiin jihada socodka hadda ee I - barta PLC. (Fiiro gaar ah: Tani waxay ka soo horjeedaa qeexida ay isticmaasho Mitsubishi PLCs, taas oo ku salaysan jihada socodka hadda ee terminalka COM.)

Nooca - nooca : Marka hadda uu ka soo baxo dhibicda I, waxaa loo tixgeliyaa isha hadda jirta.

Nooca Quuska : Marka hadda uu ku soo qulqulo barta I-, waxaa loo tixgeliyaa halka uu hadda socdo.

Isku xirka NPN Sensors iyo PLC (Source - nooca Input for Siemens PLC): Socodka hadda: 24V + → COM terminal → I0.0 (hadda ka soo baxa I - dhibic) → dareemayaasha terminal → dareenka 0V terminal → 0V.

Ku xidhida Dareemayaasha PNP PLC (Sink-nooca Input for Siemens PLC): Socodka hadda: 24V + → dareemayaasha 24V → dareemayaasha terminal → I0.0 (hadda qulqulaya I - dhibic) → COM → 0V.

Kala soocida dareemayaasha

NPN (Source-nooca): Marka la furo, waxay soo saartaa calaamad hoose.

NPN - MAYA (Caadi ahaan Furan): Wax soo saar ah ma jiro marka aan la hawlgelin; waxay soo saartaa calaamad hoose marka la hawlgeliyo.

NPN - NC (caadi ahaan xiran): Waxay soo saartaa calaamad hoose marka aan la hawlgelin; wax soo saar ah ma jiro marka la dhaqaajiyo.

NPN - NC + MAYA (Lagu daray Caadi ahaan Furan iyo Caadi ahaan xiran) : Laba terminal wax soo saar (mid furan, mid xiran).

PNP (Sink-nooca): Marka la hawlgeliyo, waxay soo saartaa calaamad heer sare ah.

PNP - MAYA (Caadi ahaan Furan): Wax soo saar ah ma jiro marka aan la hawlgelin; soo saara signal heer sare ah marka la hawlgeliyo.

PNP - NC (Caadily xiran): Waxay soo saartaa calaamad heer sare ah marka aan la hawlgelin; wax soo saar ah ma jiro marka la dhaqaajiyo.

PNP - NC + MAYA (Lagu daray Caadi ahaan Furan iyo Caadi ahaan xiran) : Laba terminal wax soo saar (mid furan, mid xiran).

Farqiga aasaasiga ah ee u dhexeeya PNP iyo NPN Sensors

Dareemayaasha PNP iyo NPN labaduba waa dareemaha nooca beddelka ah ee isticmaala saturation iyo goynta transistor-ka si ay u soo saaraan laba gobol. Si kastaba ha ahaatee, calaamadaha wax soo saarka ayaa ka soo horjeeda: NPN waxay soo saartaa calaamad hoose (0V), halka PNP ay soo saarto calaamad heer sare ah (24V).

Dareemayaasha PNP iyo NPN waxaa loo kala saaraa lix nooc:

NPN - MAYA (caadiyan furan)

NPN - NC (caadiyan xiran)

NPN - NC + MAYA (Lagu daray Caadi ahaan Furan iyo Caadi ahaan Xidhan)

PNP - MAYA (caadiyan furan)

PNP - NC (caadiyan xidhan)

PNP - NC + MAYA (Lagu daray Caadi ahaan Furan iyo Caadi ahaan Xidhan)

Dareemayaasha PNP iyo NPN waxay sida caadiga ah leeyihiin saddex hoggaan: khadka sahayda korantada (VCC), khadka 0V, iyo xariiqda soo saarista calaamadda.

Nooca PNP: Marka la kiciyo, xariiqda bannaanku waxay ku xidhmaysaa khadka korantada (VCC), isaga oo soo saaraya calaamad heer sare ah.

PNP - MAYA: Khadka bannaanku wuu furan yahay (oo ka go'ay VCC) marka aanu kicin. Marka la kiciyo, waxay soo saartaa isla danab la mid ah kan khadka korontada VCC (calaamadaha heerka sare).

PNP - NC : Khadka dibadda ayaa ku xiran khadka korontada VCC (soo saaraya calaamad heer sare ah) marka aan kicin. Marka la kiciyo, khadka bannaanku wuu furan yahay (oo ka go'ay VCC).

PNP - NC + MAYA: Waxay leedahay terminal dheeraad ah oo dibadda ah, kaas oo loo isticmaali karo haddii loo baahdo.

Nooca NPN : Marka la kiciyo, xariiqda dibadda ayaa ku xireysa xariiqda 0V, soo saarista calaamad hoose.

NPN - MAYA: Khadka dibadda ayaa furan (oo ka go'ay 0V) marka uusan kicin. Marka la kiciyo, waxay soo saartaa danab la mid ah xariiqda 0V (calaamadaha heerka hoose).

NPN - NC : Xariiqda dibadda waxay ku xiran tahay xariiqda 0V (soo saarida calaamad hoose) marka aan kicin. Marka la kiciyo, xariiqda dibadda ayaa furan (laga jaray 0V).

NPN - NC + MAYA: Si la mid ah NPN - NC + MAYA, waxay leedahay terminal dheeraad ah oo dibadda ah, kaas oo loo isticmaali karo hadba sida loogu baahdo.

Dareemayaasha NPN waxay soo saaraan calaamad hoose (0V), halka dareemayaasha PNP ay soo saaraan calaamad heer sare ah (24V).

Tusaale ahaan, haddii tamarta dareemaha ay tahay 24V, dareeme NPN wuxuu soo saari doonaa 0V, halka dareeme PNP uu soo saari doono 24V.

Marka lagu xidho gelinta PLC, haddii ay tahay wax-soo-saarka NPN, gelinta PLC-ga COM waa in lagu xidhaa 24V. Taa beddelkeeda, haddii ay tahay wax-soo-saarka PNP, gelinta PLC waa in lagu xidhaa 0V.

Furaha ayaa ah in la fahmo waxa PNP iyo NPN ay matalaan. P waxay u taagan tahay togan, N waxay u taagan tahay diidmo. PNP waxay tusinaysaa calaamada heerka sare ee xaaladaha caadiga ah, calaamaduna waxay noqotaa mid xun marka la kiciyo. NPN waxay tusinaysaa calaamada heerka hoose ee xaaladaha caadiga ah, calaamaduna waxay noqotaa heer sare marka la kiciyo. Soo saarida furayaasha u dhow iyo furayaasha korantada sawirku waa isku mid, laakiin wareegyadooda ogaanshaha way kala duwan yihiin. Xagga xadhkaha PLC, noocyada NPN ayaa inta badan la isticmaalaa. Inta badan PLC-yada Japan ee Shiinaha waa nooc - nooc ama nooc caalami ah, kaas oo si toos ah u isticmaali kara dareemayaasha NPN. Terminal-ka togan ee is-beddelka dhow iyo sahayda koronto-is-beddelka sawir-qaadista waxay ku xiran tahay korontada togan, terminalka taban wuxuu ku xiran yahay terminalka caadiga ah, wax-soo-saarka wuxuu ku xiran yahay terminal-gelinta PLC.

Marka la soo koobo, wareegtada wax gelinta tirada PLC-yada, Japanese Mitsubishi PLCs waxay u muuqdaan kuwo wax ku ool ah oo la isku hallayn karo marka loo eego qaar ka mid ah PLC-yada caanka ah sida Siemens. Sababta ugu weyn ayaa ah in PLC-yada Japan, oo ay ku jiraan Mitsubishi, ay hagaajiyeen naqshadda ay barteen
