Ngā Pūrongo Hua

I roto i ngā taiao ahumahi morearea kei reira te hau mura, te kohu me te puehu mura e tūpono tonu ana ki te pahūtanga, ko te taura haumaru ā-roto (IS) he mea nui hei whakahaere haumaru hangarau mō ngā taputapu iti-mana, ngā whakawhitiwhiti kōrero me ngā ara iahiko whakahaere. He rerekē ki ngā taura whānui noa, ko ngā taura haumaru ā-roto he mea hanga hei whakawhāiti i te tukunga hiko i raro i ngā āhuatanga mahi noa me ngā āhuatanga hapa, me te whakakore i ngā pūtake mura pea.

Me kikorangi mārama ngā taura haumaru ā-roto (RAL 5015) e ai ki te IEC 60079-14 hei tautuhi i ngā wāhi morearea.
Mā tēnei waehere tae ā-ture ka taea e ngā kaimahi hiko te wehewehe tonu i ngā taura hiko IS mai i ngā taura hiko ehara i te IS, ā, ka ārai i te hononga tūpono o te hiko morearea.
Akohia ngā whakaritenga me ngā tūponotanga.

Kua hangaia he taura haumaru ā-roto (IS) hei kawe i te pūngao hiko iti e kore e mura i roto i ngā hau pahū.

He rerekē ngā taura ātete-pahū e mau ana ngā pahūtanga, ka ārai katoa ngā taura IS i ngā mura. Akohia te whakamāramatanga o te taura IS, ngā whakaritenga hanga, te waehere tae kikorangi o te takotoranga, me ngā tawhā hinonga e ai ki te IEC 60079-11.

Kāore e taea e te taura haumaru ā-roto te whakaputa, te penapena rānei i te kaha hiko e ranea ana hei mura i roto i ngā hau pahū. Akohia te whakamāramatanga, te mahi a ngā arai whakawhāiti-kaha, te hiranga o te kaha iti (C) me te kaha iti (L), me te take e hiahiatia ai te waehere tae kikorangi puta noa i te ao mō ngā whakaurunga wāhi morearea.

Ka whakawhāitihia e te taura taputapu Haumaru ā-roto (IS) te kaha hiko hei ārai i ngā pahūtanga i ngā wāhi morearea. Kāore i rite ki ngā hoahoa ātete-pahūtanga (Ex-d) e mau ana i ngā pahūtanga, ka aukatihia e ngā taura IS te mura mā te whakahaere i te ngaohiko/iahiko. Akohia ngā uhi kikorangi, ngā whakaritenga ārai, me ngā tawhā hinonga e ai ki te IEC 60079-11.

Ka whakawhāitihia e ngā taura Haumaru ā-roto (IS) te pūngao hiko hei ārai i te mura i roto i ngā hau keri pahū. Kei roto ko ngā tawhā capacitance/inductance whakahaeretia me te waehere tae kikorangi-mārama e ai ki te IEC 60079-11, ngā kōwhiringa parepare kua tirotirohia ngā whakatauranga Ex-ia/Ex-ib, me ngā hoahoa taura pūoko ngāwari mō te tutuki i ngā whakaritenga haumaru keri whenua.

He maha ngā taura papatahi (rīpene/FFC) he mea penapena wāhi, he mea tino pai mō te mahi karetao me te aunoatanga. Kei roto ko te whakamarumaru FEP (-90°C ki te +200°C), ngā kōwhiringa kawe (CU/TC/SPC/NPC), me te parenga ārai, ārai kore rānei. Kei roto i tēnei aratohu te tuku raraunga tere-teitei, ngā painga hoahoa kiato, me ngā paearu whiriwhiri mō ngā tono karetao uaua.

Kāo, ehara te RS485 me te CAT6 i te mea ōrite. Kua hangaia ngā taura RS485 mō ngā whakawhitiwhiti kōrero ā-ahumahi tawhiti (1,200m) me te aukati 120Ω mō ngā whatunga Modbus RTU. Kua hangaia ngā taura CAT6 mō te Ethernet tere-teitei (100m, aukati 100Ω) i roto i ngā taiao tari/LAN. Ka whakatauritehia e tēnei aratohu neke atu i te 12 ngā tawhā matua hei āwhina i ngā kaihangarau ki te tautuhi tika.

He rerekē ngā mahi a ngā taura RS485 me ngā taura Ethernet i roto i ngā whakawhitiwhiti kōrero ā-ahumahi. Ka whakatauritehia e tēnei aratohu ō rātou whakaritenga, ngā whakaritenga tiaki, me ngā tono tino pai hei āwhina i a koe ki te whiriwhiri tika.

Kimihia te take Ngā taura RS485 ko rātou ngā kaiārahi mākete i roto i te aunoatanga ahumahi. Akohia te pārongo mō te aukati (120Ω), ngā rauemi tiaki, me pēhea te whiriwhiri i te ine tika mō ngā pūnaha Modbus me CANopen.
