24V - lub hauv paus ntawm lub hwj chim ntsuas tshuab

Hauv plawv ntawm txhua fais mov tam sim no measuring system yog lub hwj huam mov 24V. Yog tsis muaj kev koom tes los ntawm lub caij nws yog tsis yooj yim sua kom ua hauj lwm tej voj. Nws khiav hauj lwm kuj yog raws li nram no: tag nrho cov hluav taws xob yog sau sequentially nyob rau hauv ib tug loj nplhaib, uas yeej tam sim no (feem ntau ib tug 4-20 MA). Lub hwj chim mov yog 24 V voltage qhov chaw. Tus nqi ntawm cov tam sim no sensor hloov nyob rau hauv ib lub parameter. Nyob rau hauv lub analog tswv yim ua hauj lwm pab raws li lub receiver muaj xws li. Los ntawm cov saum toj no nws yog tseeb hais tias los ntawm nws cov high-zoo thiab txhim khu kev qha cov lag luam nyob rau hauv lub lag luam los ntawm lwm cov Cheebtsam ntawm lub system.

shemotehnicheskogo siv

Muaj pes tsawg leeg ntawm tej kev ntaus muaj xws li cov nram qab no modules:

• Fuse mus.
• Kauj ruam-down transformer.
• Diode choj.
• Lim.
• tswj tsev.

Fuse - ib tug fuse, uas tiv thaiv tus ntaus ntawv tiv thaiv overload. Thaum lub tswv yim no yog siab tam sim no, nws yuav hlawv, yuav ua rau tag nrho cov system yog de-energized. Nyob rau hauv cov ntaub ntawv no, tag nrho cov Cheebtsam nyob twj ywm ua hauj lwm. Ib tug transformer muaj ob coils. Cov Thawj zaug ntawm lawv - yog thawj (nws tau txais kev pab 220), thiab lwm yam - lub theem nrab, uas puv 24B. Hais tias yog, nws cia li yuav luag lowers tus voltage. Diode choj ntawm lub ac teeb liab ua rau lawm. Lim stabilizes tag nrho cov zis tsis vim muaj ntau yam smoothing hloov mus hloov los. Qhov kawg tivthaiv - cov tswj tsev - yuav tsuas muaj nyob rau hauv xws niaj hnub pab kiag li lawm raws li lub hwj huam mov 24V. nws ntsuas saib tso zis Pib ntsais koj teeb. Yog hais tias lawv tuaj tsis pub dhau ntau yam, de-ceev tam sim no lub voj. Nyob rau tib lub sij hawm, qhov teeb meem no yog tswj raws li ntev raws li lawv tus nqi tsis rov qab mus rau qub.

kev yam ntxwv

• Qhov siab tshaj plaws tso zis tam sim no.
• Lub hwj chim mov muaj peev xwm.
• Tus xov tooj ntawm cov zis raws.
• Ingress pab tiv thaiv.
• Mount hom.
• Ua hauj lwm ntau yam kub.

Thawj ob tsis muaj sib xyaw. Piv txwv li, yog tias lub siab tshaj plaws pub tso zis tam sim no 22mA, lub hwj chim ib yam yuav ces mus txog 5,28 watts (22 ma multiplied by 24, tam sim no rau voltage). Yuav kom txo tau qhov chaw, uas yog koom nyob rau hauv xws li nyob rau hauv lub xab khoom, siv multichannel qhov chaw. Nws yog tsis txhaum nyob rau hauv tus neeg mob qhov twg lub system muaj ib tug plurality ntawm kev ntsuas tsis. Enclosure denoted los ntawm cov tsiaj ntawv «IP» thiab hais txog zauv index. Lub siab dua nws yog, qhov ntau muaj kev ruaj ntseg txhua yam hauv yog kev tiv thaiv. Qhov no tus nqi yog tsim nyog them sai sai mus thaum yuav khiav lag luam nyob rau hauv hostile ib puag ncig (xws li, tshuaj los yog metallurgical industries). Los ntawm hom ntawm fastening xws li yog ob hom: cov ntsia hlau thiab DIN rail mounting. Cov Thawj zaug ntawm lawv - yog outdated kev hloov kho uas maj mam tawm mus ntawm kev siv. Cov yav tas yog mounted rau ib tug tshwj xeeb khib, thiab hais tias hnub no tau los ua ib lub tsib facto txheem. Qhov kawg parameter, uas characterizes lub hwj huam mov 24B - ib tug ntau yam ntawm kev khiav hauj lwm kub. Nws yog tsim nyog them sai sai yog hais tias koj npaj yuav khiav lag luam nyob rau hauv ib co huab tej yam kev mob (piv txwv li, thaum tus nqi ntawm no parameter yuav poob rau rho tawm 40-50 degrees Celsius).

Yuav ua li cas los xaiv?

xaiv algorithm xws li nram qab no. Txiav txim seb tus xov tooj ntawm cov neeg siv thiab lawv tag nrho muaj peev xwm. Xav hais tias yuav tsum tau ua hauj lwm nrog ib tug haib solenoid valve rau 100W thiab tam sim no nyob rau ntawm lub ncov load nyob rau hauv 5A. Nws yog pom zoo kom noj fais fab cia ntawm txog 20%. Ua li no, muab los ntawm 1.2 100W, 120W tau - lub hwj chim, qhia tias peb lub hwj chim mov 24V 5A (120W / 24V) yuav cia li xws li ib tug ua tau zoo. Nws yog vim hais tias ntawm pab kiag li lawm nrog nta thiab yuav tsum tau xaiv. Tom ntej no, koj yuav tsum nqa mus rau hauv tus account lub operating tej yam kev mob thiab kub, yog tias tsim nyog.

Yuav kom saib lub ntsab lug

24V - qhov no yog ib tug tseem ceeb heev tivthaiv ntawm cov niaj hnub automation tshuab. Yog tsis muaj lawv nws tsis yooj yim sua kom tiav cov hauj lwm ntawm tej xab system niaj hnub no. Los ntawm lawv xaiv yuav tsum tau mus heev kom huv si. Nyob rau hauv cov ntaub ntawv ntawm breakage ntawm xws tivthaiv tej zaum yuav ua rau kev puas tsuaj thiab lwm qhov chaw ntawm lub cev.
