PHD-22HD-2121
Mwachidule
Chotchinga chapayokha chachitetezo kumbali yodziwika: PHD-22HD-2121, kuyika kwa analogi ndi kutulutsa, kuyika kwapawiri ndi kutulutsa kwapawiri.
Chotchinga chakutali chingathe kudzipatula ndikutumiza chizindikiro cha 4 ~ 20mA kapena chizindikiro cha DC 4 ~ 20 mA chopangidwa ndi chopatsira m'malo owopsa kupita kumalo otetezeka. Pamene transmitter ndi awiri waya kapena atatu waya dongosolo, chotchinga chitetezo chimapereka mphamvu kwa transmitter.
Izi zimafuna magetsi odziyimira pawokha.
Izi zimathandizira chizindikiro cha HART ndi alamu yolumitsa.
Zofotokozera
| Mphamvu yamagetsi | 20 ~ 35VDC, kugwiritsa ntchito mphamvu |

| Mphamvu ya insulation | Pakati pa mbali yotetezedwa mwakuthupi ndi mbali yosakhala yotetezeka (≥3000VAC / min); pakati pa magetsi ndi mbali yomwe si yotetezeka kwenikweni (≥1500VAC/min) |
| Insulation resistance | ≥100MΩ (pakati pa zolowetsa/zotulutsa/magetsi) |
| Miyeso yakunja | Makulidwe 15.8mm * m'lifupi 104.8mm * mkulu 116.1mm |
| Kugwirizana kwa electromagnetic | Malinga ndi IEC 61326-1 (GB/T 18268), IEC 61326-3-1 |
| Chizindikiro chosaphulika | [Exia Ga]IIC, [Exia Da]IIIC |
| Chitsimikizo chachitetezo chogwira ntchito | SIL2 malinga ndi IEC 61508 EN 61511 miyezo |
| Bungwe la Certification | CQST(China National Quality Supervision and Test Center for Explosion Protected Electrical Products) |
| Magawo ovomerezeka (pakati pa ma terminal 1-3) Magawo ovomerezeka (pakati pa ma terminal 2-3,2-1) | Um=250V Uo=7.2V Io=-- Po=-- Co=12μF Lo=-- Um=250V Uo=28V Io=93mA Po=0.65W Co=0.083μF Lo=4.2mH |
| Zofunikira za malo oyika | Itha kulumikizidwa ndi zida za 0 zone ndi ⅡA, ⅡB, ⅡC mpweya wowopsa |
| Mtengo wa MTBF | ≤100000h |
