ABB 07NG20 GJR5221900R2

Digital input module yog ib qho tseem ceeb hauv kev tswj hwm automation. Nws lub luag haujlwm tseem ceeb yog hloov cov teeb liab digital ntawm cov khoom siv sab nraud rau hauv lub teeb liab uas lub kaw lus tswj tau lees paub thiab ua tiav, kom paub meej qhov kev saib xyuas thiab kev tswj hwm ntawm qhov system. Nws tuaj yeem sau ob lub xeev cov cim ntawm lub cuab yeej sab nraud, xws li nias lossis tso lub pob, qhib thiab tawm ntawm qhov txwv hloov, qhov tshwm sim thiab tsis tshwm sim ntawm lub sensor, thiab lwm yam, thiab hloov mus rau hauv cov teeb liab digital. (feem ntau yog sawv cev los ntawm 0 thiab 1) thiab xa mus rau qhov system tswj. Piv txwv li, ntawm ib qho kev sib dhos automated, cov khoom tuaj txog nrhiav pom tau txuas nrog los ntawm cov khoom siv digital. Thaum cov khoom mus txog qhov chaw teev tseg, lub sensor tau tshwm sim, thiab cov khoom siv digital nkag mus ntes cov teeb liab thiab ceeb toom rau kev tswj hwm kom ua haujlwm tom ntej.

Lub module xa cov cim digital sau los tswj cov tshuab xws li programmable logic controllers (PLCs) thiab cov khoos phis tawj uas siv cov qauv kev sib txuas lus. Piv txwv li, nyob rau hauv ib tug ntse Hoobkas Rhiav, ib tug loj tus naj npawb ntawm cov input modules yog faib nyob rau hauv ntau yam kev sib txuas. Cov ntaub ntawv khaws tseg yog sib npaug sib kis thiab tshuaj xyuas thiab ua tiav los ntawm lub hauv paus tswj hwm kom ua tiav qhov kev saib xyuas hauv nruab nrab thiab kev tswj hwm ntawm cov txheej txheem tsim khoom.
Hauv ib puag ncig kev lag luam, kev khiav hauj lwm voltage thiab tam sim no ntawm cov khoom siv sab nraud hloov pauv tau zoo heev, thiab muaj kev cuam tshuam electromagnetic. Cov khoom siv hluav taws xob digital tuaj yeem cais tawm sab nraud los ntawm cov kab hluav taws xob sab hauv ntawm kev tswj hwm los tiv thaiv kev cuam tshuam sab nraud thiab qhov txawv txav tsis zoo thiab tam sim no los ntawm kev puas tsuaj rau kev tswj hwm, thiab txhim kho kev ruaj ntseg thiab kev ntseeg siab ntawm lub system. Piv txwv li, hauv cov nroj tsuag metallurgical, nyob rau hauv muaj zog electromagnetic cuam tshuam, kev tiv thaiv kev sib cais ntawm cov tswv yim digital tuaj yeem ua kom muaj kev ua haujlwm zoo ntawm kev tswj hwm.
