Pehea e helu ai i nā hui i koi ʻia:
| Kaʻanuʻu | Ka helu ʻana | Laʻana |

（ʻO ka ʻāpana kea o ke kaula mea hana pālua）
Ma ke kaula ʻo Dingzun,Hana mākou i nā kaula pālua he nui i nā helu maʻamau (2, 4, 6, 8, 10, 12, 16, 20, 24, 30, 36, 48, 50, 60, 100 mau pālua) a me kekahi helu maʻamau āu e kuhikuhi ai.
- KaʻAnuʻu Hana 2: Koho i ka Nui o ke Alakaʻi Kūpono (AWG / mm²)
Hoʻoholo ka nui o ke alakaʻi i ke kū'ē ʻana o ka loop, kahi e hoʻopilikia pololei ai i ka mamao e hiki ai iā ʻoe ke holo i kahi loop 4-20mA a i ʻole ke kamaʻilio kikohoʻe.
Papa 2: Koho ʻana i ka nui o ke alakaʻi - 18 a 24 AWG (0.5 a 2.5 mm²)
| Ka nui o ke alakaʻi | AWG | Ke kū'ē (Ω/km) | Ka mamao maʻamau o ka loop 4-20mA (ma 24V, 250Ω ukana) | Noi maikaʻi loa |
| 0.5 mm² | 20 AWG | ~33 Ω/km | 500-800 mika | Holo pōkole a waena, pili i ke kumukūʻai |
| 0.75 mm² | 18-19 AWG | ~24 Ω/km | 800-1,200 mika | Kūlana maʻamau no ka hapa nui o nā mea hana ʻoihana |
| 1.0 mm² | 17-18 AWG | ~18 Ω/km | 1,200-1,500 mika | Nā holo lōʻihi, nā pōʻai kū'ē kiʻekiʻe |
| 1.5 mm² | 16 AWG | ~13 Ω/km | 1,500-2,000+ mika | Nā holo lōʻihi loa, nā mea hana makewai mana |
| 2.5 mm² | 14 AWG | ~8 Ω/km | >2,500 mika | Nā noi kūikawā (mamao loa) |
Pehea e helu ai i ka lōʻihi o ka loop (4-20mA):
Ua kaupalena ʻia ka loop 4-20mA e ke kū'ē ʻana o ka loop holoʻokoʻa = ke kū'ē ʻana o ke kaula (nā ʻaoʻao ʻelua) + ke kū'ē ʻana o ka ukana (250Ω maʻamau) + ke kū'ē ʻana o ka pale (inā hoʻohana ʻia).
| Palena | Haʻilula | Laʻana |
| Ke kū'ē ʻana o ka loop kiʻekiʻe loa (ma ka lako 24V) | (Vsupply - Vmin_device) / 0.02A | (24V – 12V) / 0.02A = 600Ω |
| E hoʻemi i ka ukana a me ke keʻakeʻa | 600Ω – 250Ω (kaumaha) – 50Ω (pale) = 300Ω | Loaʻa no ke kaula |
| Ke kū'ē ʻana o ke kaula (kaʻahele a puni) | 2 × R_km × Ka mamao (km) | 2 × 24Ω/km × 1.2km = 57.6Ω |
| Ka mamao loa no 0.75mm² (18 AWG) | Ke kū'ē'ē o ke kaula i loa'a / (2 × R_km) | 300Ω / (2 × 24Ω/km) =6.25 km? Kiʻekiʻe loa - e nānā i ka hāmeʻa |
*(Nānā: Ua kaupalena ʻia ka mamao kūpono o 4-20mA e ka mana o ka hāmeʻa a me ka capacitance, pinepine 800-1,500m max no 18 AWG)*
No nā Hōʻailona Kikohoʻe (RS485, Modbus):
| Ka nui o ke alakaʻi | Ka mamao loa (ma 9.6 kbps) | Kumu Hoʻemi |
| 24 AWG (0.2mm²) | 1,200 mika (maʻamau RS485 max) | Ka hiki ke hoʻemi a me ka hōʻemi ʻana |

| 18-20 AWG | 1,200 mika | ʻAʻole pono ka mānoanoa ma ke ʻano uila; e hoʻohana no ka ikaika mechanical |
Manaʻo:No ka hapa nui o nā mea hana ʻoihana (4-20mA, RS485, RTD, thermocouple),0.75mm² – 1.0mm² (18 AWG)ʻo ia ke koho maʻamau - ke kaulike ʻana i ke kumukūʻai, ka hiki ke mamao, a me ka ikaika mechanical. E hoʻohana i nā nui nui no nā loop lōʻihi loa a i ʻole kahi e hopohopo ai ka ikaika huki mechanical.
Ma ke kaula ʻo Dingzun,Hāʻawi mākou i nā kaula pālua he nui me 18 AWG (0.75mm²) ma ke ʻano maʻamau, me 16 AWG (1.5mm²), 20 AWG (0.5mm²), a me nā ana maʻamau i loaʻa no kāu helu ʻana i ka lōʻihi o ka loop.

Ka Noʻonoʻo Kūikawā no nā Pālua He nui - Crosstalk:
Ke kaʻana like nā hui he nui i ke kaula like, hiki i nā hōʻailona mai kekahi hui ke hoʻopili capacitively i nā hui pili (crosstalk). ʻO ka hopena:
