I loko o nā wahi ʻoihana weliweli kahi e hoʻoulu ai ke kinoea lapalapa, ka mahu a me ka lepo lapalapa i nā pilikia pahū mau, hōʻike ke kaula palekana kūloko (IS) i kahi kaohi palekana ʻenekinia koʻikoʻi no nā mea hana mana haʻahaʻa, kamaʻilio a me nā kaapuni kaohi. ʻAʻole e like me nā kaula kumu maʻamau, ua hoʻolālā ʻia nā kaula palekana kūloko e kaupalena i ka hoʻokuʻu ʻana o ka ikehu uila ma lalo o nā kūlana hana maʻamau a me nā hewa, e hoʻopau ana i nā kumu hoʻā ahi hiki ke hiki.

Pono nā kaula palekana kūloko he uliuli māmā (RAL 5015) e like me IEC 60079-14 no ka ʻike ʻana i nā wahi weliweli.
ʻAe kēia code kala i koi ʻia i nā mea uila e hoʻokaʻawale koke i nā kaapuni IS mai nā kaula mana ʻaʻole IS, e pale ana i ka pili ulia pōpilikia o ka ikehu weliweli.
E aʻo i nā koi a me nā ʻokoʻa.

Ua hoʻolālā ʻia kahi uwea palekana kūloko (IS) e lawe i ka ikehu uila i kaupalena ʻia ʻaʻole hiki ke hoʻā i nā lewa pahū.

ʻAʻole e like me nā kaula pahū e loaʻa ana nā pahū, pale loa nā kaula IS i nā huna ahi. E aʻo i ka wehewehe ʻana o ke kaula IS, nā koi kūkulu ʻana, ke code kala ʻulaʻula polū, a me nā palena o nā mea e like me IEC 60079-11.

ʻAʻole hiki i kahi uwea palekana maoli ke hoʻoulu a mālama paha i ka ikehu uila lawa e hoʻā ai i nā lewa pahū. E aʻo i ka wehewehe ʻana, pehea e hana ai nā pale e kaupalena ana i ka ikehu, no ke aha he mea nui ka capacitance haʻahaʻa (C) a me ka inductance haʻahaʻa (L), a no ke aha e koi ʻia ai ke code kala polū ma ka honua holoʻokoʻa no nā hoʻonohonoho wahi weliweli.

Hoʻopaʻa ka uaea mea kani Intrinsically Safe (IS) i ka ikehu uila e pale aku i nā pahū ma nā wahi weliweli. ʻAʻole e like me nā hoʻolālā pale pahū (Ex-d) i loaʻa nā pahū, hoʻōki nā uaea IS i ka hoʻā ʻana ma ka kaohi ʻana i ke au uila/au. E aʻo e pili ana i nā ʻūpā polū, nā koi pale, a me nā palena o ka hui e like me IEC 60079-11.

Hoʻopaʻa nā kaula Intrinsically Safe (IS) i ka ikehu uila e pale aku i ka hoʻā ʻana i nā lewa eli pahū ana. Loaʻa iā lākou nā palena capacitance/inductance i kāohi ʻia me ke kala polū māmā-uliuli e like me IEC 60079-11, nā koho pale i pale ʻia e like me nā helu Ex-ia/Ex-ib, a me nā hoʻolālā kaula sensor maʻalahi no ka mālama ʻana i ka palekana o ka eli ʻana ma lalo o ka honua.

ʻO nā kaula pālahalaha (ribbon/FFC) he mau ʻākoakoa multi-conductor e mālama ana i ka wahi, kūpono no ka robotics a me ka automation. Loaʻa iā lākou ka FEP insulation (-90°C a i +200°C), nā koho conductor (CU/TC/SPC/NPC), a me ka pale pale ʻia a pale ʻole ʻia paha. Uhi kēia alakaʻi i ka hoʻoili ʻikepili wikiwiki, nā pono hoʻolālā compact, a me nā pae koho no nā noi robotic koi.

ʻAʻole, ʻaʻole like ʻo RS485 a me CAT6. Ua hoʻolālā ʻia nā kaula RS485 no ke kamaʻilio ʻoihana mamao loa (1,200m) me ka impedance 120Ω no nā pūnaewele Modbus RTU. Ua hoʻonohonoho ʻia nā kaula CAT6 no ka Ethernet wikiwiki (100m, 100Ω impedance) ma nā wahi keʻena/LAN. Hoʻohālikelike kēia alakaʻi i nā palena koʻikoʻi he 12+ e kōkua i nā ʻenekinia e kuhikuhi pololei.

Hoʻohana nā kaula RS485 a me Ethernet i nā kumu like ʻole i ke kamaʻilio ʻoihana. Hoʻohālikelike kēia alakaʻi i kā lākou mau kikoʻī, nā koi pale, a me nā noi kūpono e kōkua iā ʻoe e hana i ke koho kūpono.

E ʻike i ke kumu Nā kaula RS485 ʻo lākou nā alakaʻi mākeke i ka automation ʻoihana. E aʻo e pili ana i ka impedance (120Ω), nā mea pale, a pehea e koho ai i ke ana kūpono no nā ʻōnaehana Modbus a me CANopen.
