Okutaho obumanyiso oburikutaanisa aha kabineti z'okutegyeka PLC

Omu by’okukora eby’amakorero, PLC (Programmable Logic Controller) ebishengye by’okutegyeka nibikora omurimo muhango, biine obujunaanizibwa bw’okutunga obumanyiso kuruga omu bikwato ebitari bimwe na bimwe ebirikumanyisa n’ebirikukora, n’okuhikiiriza okutegyeka okuhikire kw’omuringo gw’okukora ebintu kurabira omu mirimo y’omunda ey’okutegyeka. Kwonka omu nkora z‘omugasho, ebishengye by‘okutegyeka PLC nibikira kutunga embeera zitari zimwe na zimwe ezigumire ez‘amashanyarazi n‘ebizibu by‘okutabura obumanyiso, ekirikubaasa kureetera enkora y‘okutegyeka kutakora gye, okuremwa emirundi mingi, nangwa n‘okureetaho akabi aha bikwato n‘obukuumi bw‘abakozi. Nahabwekyo, okwongyeraho . akamanyiso akataanisiibweators kuhika aha kabineti z‘okutegyeka PLC kihindukire eky‘okushoboorora ekirikukirayo.

Emirimo mikuru y‘ebikwato ebirikutaanisa obumanyiso harimu okuzibira okujanjaara kw‘okutabura kw‘amashanyarazi, okukyendeeza aha kubaho kw‘okuremwa kw‘enkora, n‘okuha okwetaanisa omu mbeera y‘okuremwa kw‘ebikwato aha mwanya, okuzibira okujanjaara kw‘ebizibu omu nkora yoona ey‘okutegyeka. Omu kuhindura n‘okuhindura obumanyiso oburikutunga PLC kurabira omu bikwato bya semiconductor, bwanyima bakabitaanisa n‘okubihindura barikukoresa eby‘okukoresa eby‘okureeba nari eby‘amashanyarazi, kandi aha muheru bakabihindura n‘okubihindura kugaruka omu bumanyiso bw‘okubanza nari obumanyiso obutari bumwe na bumwe, omuringo ogu niguhamya okuhama n‘obuhikire bw‘obumanyiso, obwo n‘okuzibira okushiisha kw‘omutaano aha bumanyiso aha PLC- obumanyiso bw’okushoberwa. Okwongyera ahari ekyo, ebikwato ebirikutaanisa obumanyiso nabyo nibibaasa kuhikiiriza okuhindura obumanyiso, nk‘okuhindura obumanyiso kuruga omu nkoragana ya PT10 kuza omu bumanyiso bwa 4-20mA n‘okubuta omu nkora za PLC, omu muringo murungi okwetantara obutaikirizana ahagati y‘amashanyarazi n‘enshonga z‘amaani n‘okumaraho ekizibu ky‘okutaaha omu nshonga ahagati y‘ebikwato n‘ebikwato.

Omu mirimo emwe, nk‘omu nkora y‘okukora eby‘ekyoma, okupima n‘okutegyeka nibihikirizibwa kurabira omu PLC, ebikwato by‘okukora eby‘omu mwanya, n‘ebikwato by‘okukora eby‘omu mwanya. PLC neeteebwa omu kabineti y‘okutegyeka erikushangwa mita nka magana maingi kuruga aha mwanya (erikukora aha bwire bw‘obutagatsi bw‘omu kishengye), kandi ebikwato by‘okukora nari thermocouples kuruga omu mwanya nibireetaho obumanyiso kurabira omu waya kuza omu kabineti y‘okutegyeka omu kishengye ky‘okutegyeka. Omu bwire obu, akamanyiso akarikutaaha omu PLC kaine kwetaanisa kandi nikabaasa n’okwetaaga kuhindurwa, nk’okwetaanisa 4-20mA n’okukahindura 0-5V katakataahire omu PLC. Ebikwato ebirikuheza okwetaanisa n'okuhindura obumanyiso bw'okwotsya nibyetwa "obumanyiso bw'okwotsya obutagatsi" nari "obutagatsi bw'okwotsya". Omurimo gwayo omukuru nigutwariramu okwahukana kw‘akamanyiso k‘okutaaha n‘akamanyiso k‘okuruga, hamwe n‘okuhindura akamanyiso k‘okutaho akamanyiso k‘omutindo gwa mV kuruga omu thermocouple kuza omu kamanyiso k‘omutindo gw‘amakorero (4-20mA, 0-5V, 0-10V).

Omu bugufu, okutaho ebikwato ebirikutaanisa obumanyiso n‘eky‘omugasho munonga omu kutunguura okwesigwa kw‘enkora z‘okukora eby‘amakorero, okukyendeeza aha mibaro y‘okuremwa, okurinda eby‘okukoresa bya PLC, n‘okutunguura omutindo gw‘obumanyiso. Ni kimwe aha bintu bikuru kureeba ngu enkora z‘okutegyeka zaakora gye kandi zirikwesigwa .
