Ho utloisisa Mefuta ea Input Terminal ea PLCs : Litlhaloso tsa mofuta oa mohloli - mofuta le sink - bakeng sa li-terminals tsa Siemens PLC tsa ho kenya li itšetlehile ka tataiso ea phallo ea hona joale sebakeng sa I - ntlha ea terminal ea PLC. (Tlhokomeliso: Sena se hanana le tlhaloso e sebelisoang ke Mitsubishi PLCs, e ipapisitseng le tataiso ea phallo ea hajoale boemelong ba COM.)

Mohloli - mofuta : Ha hona joale ho phalla ho tsoa ho I - ntlha, ho nkoa e le mohloli oa hona joale.

Sink - mofuta : Ha hona joale e phalla ho I - ntlha, e nkoa e le sebaka sa ho ea hona joale.

Ho kopanya NPN Sensors ho PLC (Mohloli - mofuta oa Input bakeng sa Siemens PLC) : Phallo ea hona joale: 24V + → COM terminal → I0.0 (hona joale e phalla ho tsoa ho I - point) → sensor out terminal → sensor 0V terminal → 0V.

Ho hokela PNP Sensors ho PLC (Sink - type Input for Siemens PLC) : Phallo ea hona joale: 24V + → sensor 24V → sensor out terminal → I0.0 (hona joale e phallela ho I - point) → COM → 0V.

Sehlopha sa li-Sensors

NPN (Mohloli - mofuta) : Ha e kentsoe, e hlahisa lets'oao la boemo bo tlase.

NPN - NO (Ka tloaelo Bula) : Ha ho tlhahiso ha e sa sebetsa; e hlahisa letshwao la boemo bo tlase ha e kentswe tshebetsong.

PNP - NC + NO (E Kopantsoeng ka Tloaelo e Bulehileng le e Tloaelehileng e Koetsoe) : Li-terminals tse peli tse hlahisoang (e 'ngoe e butsoe, e' ngoe e koetsoe).

Phapang ea Motheo lipakeng tsa PNP le NPN Sensors

Li-sensor tsa PNP le NPN ka bobeli ke li-switch-type sensors tse sebelisang saturation le cutoff ea transistors ho hlahisa linaha tse peli. Leha ho le joalo, lipontšo tse hlahisoang li fapane: NPN e hlahisa pontšo ea boemo bo tlaase (0V), ha PNP e hlahisa pontšo ea boemo bo phahameng (24V).

Li-sensor tsa PNP le NPN li arotsoe ka mefuta e tšeletseng:

NPN - NO (Ka tloaelo e Bulehile)

NPN - NC (Hangata E Koetsoe)

NPN - NC + NO (E Kopantsoeng ka Hangata e Bulehile 'me e Koetsoe ka Hangata)

PNP - NO (Ka tloaelo e Buloa)

PNP - NC (Hangata E Koetsoe)

PNP - NC + NO (E Kopantsoeng ka Hangata e Bulehile 'me e Koetsoe ka Hangata)

Li-sensor tsa PNP le NPN hangata li na le li-lead tse tharo: mohala oa phepelo ea motlakase (VCC), mohala oa 0V, le mohala oa tlhahiso ea mats'oao.

Mofuta oa PNP : Ha o hlahisoa, mohala o tsoa o hokahana le mohala oa phepelo ea motlakase (VCC), o ntša lets'oao le phahameng.

PNP - NO : Mohala oa kantle o bulehile (o khaotsoe ho VCC) ha o sa qala. Ha e hlahisoa, e hlahisa motlakase o tšoanang le mohala oa phepelo ea motlakase oa VCC (letšoao la boemo bo holimo).

PNP - NC : Mohala oa ho tsoa o hokahane le mohala oa phepelo ea motlakase oa VCC (o ntšang lets'oao la boemo bo holimo) ha o sa ts'oaroe. Ha e hlahisoa, mohala oa kantle oa buleha (o khaotsoe ho VCC).

PNP - NC + NO : E na le terminal e eketsehileng, e ka sebelisoang ha ho hlokahala.

Mofuta oa NPN : Ha o hlahisoa, mohala oa kantle o hokahana le mohala oa 0V, o ntša lets'oao la boemo bo tlase.

NPN - NO : Mohala oa kantle o bulehile (o khaotsoe ho 0V) ha o sa hlahisoa. Ha e hlahisoa, e hlahisa motlakase o tšoanang le oa mohala oa 0V (letšoao la boemo bo tlase).

NPN - NC : Mohala oa ho tsoa o hokahane le mohala oa 0V (o ntšang letšoao la boemo bo tlaase) ha o sa susumetsoe. Ha e hlahisoa, mohala oa kantle oa buleha (o khaotsoe ho 0V).

NPN - NC + NO : E ts'oana le NPN - NC + NO, e na le setsi sa tlatsetso sa kantle, se ka sebelisoang ha ho hlokahala.

Li-sensor tsa NPN li hlahisa lets'oao la boemo bo tlase (0V), ha li-sensor tsa PNP li hlahisa lets'oao le phahameng (24V).

Ka mohlala, haeba matla a motlakase a le 24V, mochine oa NPN o tla hlahisa 0V, ha mochine oa PNP o tla hlahisa 24V.

Ha o hokela ho kenyelletso ea PLC, haeba e le tlhahiso ea NPN, terminal ea COM ea PLC e lokela ho hokela ho 24V. Ka lehlakoreng le leng, haeba ke tlhahiso ea PNP, terminal ea PLC e lokela ho hokela ho 0V.

Ntho ea bohlokoa ke ho utloisisa hore na PNP le NPN li emela eng. P e emetse positive, mme N e emetse negative. PNP e bonts'a letšoao la boemo bo phahameng tlas'a maemo a tloaelehileng, 'me pontšo e fetoha e mpe ha e tsosoa. NPN e bonts'a letšoao la boemo bo tlaase tlas'a maemo a tloaelehileng, 'me pontšo e fetoha boemo bo phahameng ha e tsosoa. Sephetho sa li-switches tse haufi le li-switch tsa photoelectric lia tšoana, empa lipotoloho tsa bona tsa ho lemoha lia fapana. Ha e le lithapo tsa PLC, mefuta ea NPN hangata e sebelisoa hangata. Boholo ba li-PLC tsa Majapane tsa Chaena ke mofuta oa lefats'e kapa oa bokahohle, o ka sebelisang li-sensor tsa NPN ka kotloloho. Terminal e ntle ea switch ea proximity switch le photoelectric switch ea motlakase e hokahantsoe le phepelo e ntle ea motlakase, terminal e fosahetseng e hokahantsoe le terminal e tloaelehileng, 'me tlhahiso e hokahantsoe le terminal ea ho kenya PLC.

Ka kakaretso, bakeng sa switch - quantity input circuit of PLCs, Japanese Mitsubishi PLCs e bonahala e sebetsa haholo ebile e ka tšeptjoa ho feta tse ling tse tsebahalang tsa PLC tse kang Siemens. Lebaka le ka sehloohong ke hore li-PLC tsa Japane, ho kenyeletsoa Mitsubishi, li ntlafalitse moralo oo li ithutileng tsona
