PHD-11TC-33*
A tlangpi in
PHD-11TC-33* pehtlaihnak signal cu a dang tein chiahmi himnak khamnak ah luhter a si, cu nih cun RS-485 Half Duplex digital signal nih tihnung hmun le a himnak hmun ah lam pahnih in pehtlaihnak a tuah khawh. Hi thilri nih hin amah tein thazaang peknak a herh, cun thazaang peknak, luhnak le chuahnak cu aa then.
Model cakuat ah: PHD-11C-33* cafang "*" nih pekmi voltage a aiawh, cun phunglam cu a tanglei bantuk in an si:
| Code | Pekmi voltage, current |
| A silo | Pekmi thazaang a um lo |
| A | 5V |
| B | 6V |
| C | 12V |
| F | 24V |
| H | Hmantu nih a fiantermi |
* bus dinhnak mei peknak, a tawinak caah appendix zoh.
| Supply voltage | 20~35V DC, Thazaang hmannak: ≤170mA (24V thazaang peknak, 5V/200mA thazaang phawtzamhnak.) |
| Luhternak hmelchunhnak | RS485 cheukhat-duplex digital signal |
| Chuahmi signal | RS485 cheukhat-duplex digital signal |
| Luhnak le chuahnak lam zat | 1 luhternak 1 chuahnak |
| Hman khawhmi lo thilri hna | RS485 cheukhat-duplex pehtlaihnak he thilri |
| kuatnak a tlai | ≤10 μs |
| Thlennak caan cohlan le kuat | ≥20ms |
| Khuacaan tahfung | Riantuannak lumnak: -20°C~+60°C, chiahnak lumnak:-40°C~+80°C |
| Aa pehtlaimi lumternak | 10%~95% RH ah ti a luang lo |
| Dielectric thazaang | A chunglei in a himmi lei le a him lomi lei karlak (≥ 3000VAC/min); thazaang peknak le a him lomi terminal (≥ 1500VAC/min) karlak ah |
| Insulation doh khawhnak | ≥100MΩ (luhnak/chuahnak/mei thazaang peknak karlak) |

| Electromagnetic aa tlaknak | IEC 61326-1(GB/T 18268) ning in, IEC 61326-3-1 |
| A puak kho lomi hmelchunhnak | [Ex ia Ga] IIC [Ex ia Da] ⅢC |
| Cawnnak Bu | CQST(Tuluk Ram puahnak in a himmi electric thilri hna caah tthatnak zohkhenhnak le hneksaknak hmun) |
| Terminal 1-2 | Um：250V AC/DC Uo=17.8V DC Io=260mA Po=1.2W Co=0.22μF Lo=0.25mH |
| Terminal 3-4 | Um：250V AC/DC Uo=7.7V DC Io=80mA Po=0.15W Co=6.9μF Lo=5mH |
| Install tuahnak hmun a herhmi | A himnak hmun ah chiah ahcun, Zone 0, IIC, Zone 20, le IIIC tiang tihnung hmun ah a chunglei himnak thilri hna he pehtlaih khawh a si |
| MTBF | ≤100000h |
Bialehnak: Power rail riantuannak cu thim khawhmi riantuannak a si, cun hmantu hna nih an langhter a hau
order tuah tikah mei thazaang peknak lam
Power rail pehtlaihnak thimnak cu "Annex" cahmai 89 ah zoh khawh a si
