()Chingwe cholumikizira zida zamitundu yambiri）
Pa Dingzun Cable,Timapanga zingwe zamitundu yambiri m'mawerengedwe okhazikika (2, 4, 6, 8, 10, 12, 16, 20, 24, 30, 36, 48, 50, 60, 100) ndi chiwerengero chilichonse chomwe mwasankha.
- Gawo 2: Sankhani Kukula Koyenera kwa Kondakitala (AWG / mm²)
Kukula kwa kondakitala kumatsimikiza kukana kwa lupu, komwe kumakhudza mwachindunji kutalika komwe mungathe kuyendetsa lupu ya 4-20mA kapena kulumikizana kwa digito.
Gome 2: Kusankha Kukula kwa Kondakitala – 18 mpaka 24 AWG (0.5 mpaka 2.5 mm²)
| Kukula kwa Kondakitala | AWG | Kukana (Ω/km) | Mtunda Wozungulira wa 4-20mA (pa 24V, 250Ω katundu) | Ntchito Yabwino Kwambiri |
| 0.5 mm² | 20 AWG | ~33 Ω/km | Mamita 500-800 | Kuthamanga kwafupipafupi mpaka kwapakati, kotsika mtengo |
| 0.75 mm² | 18-19 AWG | ~24 Ω/km | Mamita 800-1,200 | Muyezo wa zida zambiri zamafakitale |
| 1.0 mm² | 17-18 AWG | ~18 Ω/km | Mamita 1,200-1,500 | Kuthamanga kwautali, ma loops oletsa kwambiri |
| 1.5 mm² | 16 AWG | ~13 Ω/km | Mamita 1,500-2,000+ | Zipangizo zothamanga kwambiri, zodzaza ndi mphamvu |

Momwe Mungawerengere Kutalika Kwambiri kwa Chizunguliro (4-20mA):
Chizunguliro cha 4-20mA chimachepetsedwa ndi kukana konse kwa chizunguliro = kukana kwa chingwe (njira zonse ziwiri) + kukana kwa katundu (250Ω yachizolowezi) + kukana kwa zotchinga (ngati zagwiritsidwa ntchito).
| Chizindikiro | Fomula | Chitsanzo |
| Kukana kwakukulu kwa kuzungulira (pa mphamvu ya 24V) | (Vsupply – Vmin_device) / 0.02A | (24V – 12V) / 0.02A = 600Ω |
| Chotsani katundu ndi chotchinga | 600Ω – 250Ω (katundu) – 50Ω (chotchinga) = 300Ω | Ikupezeka pa chingwe |
| Kukana kwa chingwe (ulendo wobwerera) | 2 × R_km × Mtunda (km) | 2 × 24Ω/km × 1.2km = 57.6Ω |
| Mtunda waukulu wa 0.75mm² (18 AWG) | Kukana kwa chingwe komwe kulipo / (2 × R_km) | 300Ω / (2 × 24Ω/km) =6.25 km? Pamwamba kwambiri - onani chipangizocho |
*(Dziwani: Mtunda wothandiza wa 4-20mA umachepetsedwa ndi mphamvu ya chipangizo ndi mphamvu yake, nthawi zambiri 800-1,500m pa 18 AWG)*
Za Zizindikiro Za digito (RS485, Modbus):
| Kukula kwa Kondakitala | Mtunda Waukulu (pa 9.6 kbps) | Cholepheretsa |
| 24 AWG (0.2mm²) | Mamita 1,200 (muyezo wa RS485 wopitilira) | Kuchuluka kwa mphamvu ndi kuchepa kwa mphamvu |
| 22 AWG (0.34mm²) | Mamita 1,200 | Chomwecho - mtunda osati kukana komwe kumachepetsa mphamvu ya baud |
| 18-20 AWG | Mamita 1,200 | Chokhuthala sichikufunika pamagetsi; gwiritsani ntchito mphamvu ya makina |
Malangizo:Pa zida zambiri zamafakitale (4-20mA, RS485, RTD, thermocouple),0.75mm² – 1.0mm² (18 AWG)ndiye chisankho chokhazikika - kulinganiza mtengo, kuthekera kwa mtunda, ndi mphamvu ya makina. Gwiritsani ntchito kukula kwakukulu pazitali kwambiri kapena pamene mphamvu yokoka ya makina ndi nkhani yaikulu.
