24V - isiseko lweenkqubo yokulinganisa kwamandla

Xa intliziyo nayiphi na inkqubo yokulinganisa yangoku zombane unikezelo ke 24V supply amandla. Ngaphandle inxaxheba element akunakwenzeka ukuba basebenze nayiphi loop. Yaso ephambili yokusebenza ngolu hlobo lulandelayo: zonke izixhobo zekhompyutha ziqokelelwe nangendlela ecwangciswe kakuhle ngokulandelelana kwi khonkcweni linye ezinkulu, apho ujikeleza yangoku (uninzi ngokuqhelekileyo a 4-20 MA). Umbane yi-24 V umthombo wamandla ombane. Ubungakanani utshintsho isivamvo yangoku kuxhomekeka kwi parameter. Xa igalelo analog lisebenza ngumamkeli isilawuli-mveliso. Ukusuka apha ngasentla kucacile ukuba wayo ezikumgangatho ophezulu kunye nokusebenza oluthembekileyo kuxhomekeke ukusebenza kwamanye amacandelo nkqubo.

ukuqaliswa shemotehnicheskogo

Ukubunjwa sixhobo ibandakanya ezi modyuli zilandelayo:

• links fuse.
• Inyathelo-phantsi sombane.
• Diode kwebhulorho.
• Icebo lokucoca ulwelo.
• unit control.

Fuse - ifuse, olukhusela icebo overload. Xa igalelo na ngoku eliphezulu, litshise phandle, ebangela yonke le nkqubo sele de-amandla. Kule meko, onke amacandelo zisebenza. A transformer ali-jiko ezimbini. Eyokuqala kuzo - primary (it wakhonza 220), kunye nezinye - secondary jikisa 24B. Oko kukuthi, yena kanye nje lihlisa ombane. Diode ibhulorho yomqondiso ac yenza ngokusisigxina. Icebo lokucoca omeleza zonke iparameters imveliso ngenxa yokuguquguquka ezahlukeneyo emlungisa. Icandelo lokugqibela - iyunithi yolawulo - ingafumaneka kuphela izixhobo zale mihla ezifana 24V supply amandla. ulinganisa signal kwimveliso. Ukuba beza ngaphakathi kuluhlu, de-ngaphakathi yomtya yangoku. Ngelo xesha, le meko igcinwa nje ixabiso labo ingabuyeli eqhelekileyo.

iimpawu technical

• Imveliso yangoku eliphezulu.
• Unikezelo amandla amandla.
• Inani lamajelo kwimveliso.
• Protection lingenwe.
• Mount Type.
• Operational uluhlu lobushushu.

Imida ezimbini zokuqala zihlobene. Umzekelo, ukuba isilinganiselo 22mA imveliso ngoku, iyunithi amandla kuya kufika watts 5.28 (22 ma liphindaphindwe-24, i yangoku kwamandla). Ukunciphisa isithuba, nto leyo inxaxheba izixhobo ezinjalo nekhabhathi lokulinganisa, sebenzisa imithombo kwamajelo. It onesizathu kwiimeko apho le nkqubo iqulethe ezininzi parameters yomlinganiselo. Indawo luchazwa yi ngoonobumba «IP» kunye index lwamanani. I aphezulu oko, le yonke ekhuselekileyo ngakumbi ngaphakathi likhuselwe. Eli xabiso kuyimfuneko ukunikela ingqalelo ziya kusebenza xa kwiindawo ezikhohlakeleyo (umzekelo, zeekhemikali okanye amashishini metallurgical). Xa uhlobo beqwalasele izixhobo ezinjalo kweentlobo ezimbini: Screw kunye Din kaloliwe engathethekiyo. Eyokuqala kuzo - na utshintsho lixesha esigcina aphume ukusetyenziswa. ZifunwaEzokugqibela zidweliselwe ekhwele nedawo okhethekileyo, yaye namhlanje uye waba umgangatho de facto. Parameter wokugqibela, nto leyo ubonakalise unikezelo lwamandla 24B - uluhlu kwamaqondo zokusebenza. Kuyimfuneko ukunikela ingqalelo kuphela xa uceba ukusebenza kwezinye iimeko ezinzima (umzekelo, xa ixabiso le parameter angehla Degrees 40-50 Celsius).

Indlela ukukhetha?

algorithm Ukhetho Izixhobo ezinjalo hlobo. Ukumisela inani labasebenzisi kunye nesakhono sabo setotali. Zicingele kulindeleke ukuba basebenze kunye onamandla solenoid vana ku 100W kwaye ngoku umthwalo lokubeka emgangathweni 5A. Kuyanconywa ukuba amandla bucala malunga ne-20%. Ukuze wenze oku, phinda ngo 1.2 100W, 120W ukufumana - amandla, ebonisa ukuba unikezelo amandla ethu 24V 5A (120W / 24V) iya kuba nje umsebenzi onjalo. Kungenxa izixhobo kunye neempawu kwaye kufuneka ekhethiweyo. Okulandelayo, kufuneka uthathe ingqalelo iimeko lobushushu yokusebenza, xa kukho imfuneko.

Ngamafuphi

24V - oku licandelo ebaluleke kakhulu kweenkqubo esizisebenzelayo mihla. Ngaphandle kwabo ke akunakwenzeka ukuba ukugqibezela umsebenzi nayiphi na inkqubo yokulinganisa namhlanje. Xa ukhetho lwabo kufuneka wasondela ngocoselelo kakhulu. Kwimeko breakage kwicandelo hlobo kunokukhokelela umonakalo kunye nezinye iindawo nkqubo.
