He aha tō mōhio ki ngā PLC o ngā mīhini waiariki?

I roto i te reo houmīhini waiarikiHe maha ngā pūnaha, he maha ngā rōpū piha matatini, ngā whakawhiti pēhanga, ngā whakawhiti tata, etc. e whakauruhia ana.

He tino uaua te whakaurunga i waenganui i ēnei pūwhitinga whakahaere. Nō reira, mēnā ka whakamahia te tikanga whakahaere whakapā noa, ka nui te rōrahi o te arawhata, ā, he uaua rawa te waea, kāore e pai ki te tiaki i muri mai me te pūmautanga mahi o te pūnaha mīhini hanga whao.

Ko te mana o te relay ka tutuki ma te waea taputapu, a ko te arorau whakahaere ka hangaia e te raupapa, te hononga whakarara ranei o nga whakapiri miihini o te relay me te mahi hysteresis o te relay roa.

Ka taea anake e ia te whakaoti i te mana arorau kua whakatūria. Ka whakamahia e te PLC ngā wāhanga ngohengohe hei whakahaere, ka taea te whakarerekē i te hōtaka, he tere ake te tere whakahaere, ā, he teitei ake te pono. E kore e taea e te reira anake oti mana arorau, engari mahi hoki tātaitanga raraunga me te kōrero.

Ka taea e te pūnaha mana hiko PLC me te whakatika waipēhi te whakatutuki i nga momo taputapu me nga taputapu penei i te huringa momo tere, me te tohu teitei o te mahi aunoa me te whakakapi ngawari. Na reira, i roto i ngā tono whakaputa, ahakoa he iti ngā huinga o ngā hua pēhi, he motuhake hoki i roto i ngā whakaritenga, ka taea tonu e te mīhini hauā te whakaatu i ngā āhuatanga o te kaha nui me ngā painga ohaoha pai.

I roto i te hanga o te kirihou hou, kua whakakapia te mana o ngā pūnaha mīhini hanga whao hydraulic e te mana PLC hei utu o te mana relay tuku iho.

Nā te mea he mahi o te pūnaha whakahaere PLC e kore e taea e ngā pūnaha whakahaere tūhono noa te ōrite. Kei a KY Pneumatic Nail ngā tau 30 o te pūkenga rangahau motuhake me te whanaketanga ngaio i roto i ngā mīhini waipēhi. Nau mai ki te ako atu me te tono!
