Whakatakotoranga Hua
| Ngaohiko tuku | 20~35VDC, kohi hiko |
| Tohu whakauru | Whakawhiti whakapā/whakatata tata |
| Tuku ngaohiko mai i te taha pūoko i runga i te pae | 8V |
| Nga ahuatanga whakauru tohu | I runga i te waahi whakauru o naianei: >2.1mA, ko te tikanga ON; I runga-pae whakaurunga o naianei: Whakawhiti histeresis: 0.2ms |
| Ko nga ahuatanga putanga whakawhiti | NPN momo transistor emitter ranei kaikohi tuwhera ara iahiko putanga, puku kaha: putanga nāianei ≤20mA (1.2KΩ), roto 100mA mōrahi o nāianei. Kua rite ki te whakamarutanga o naianei poto |
| Whakawhitihia te mana i waenga i te waahanga hurihuri me te waa noa o nga putanga ec | Ina kei te "ON" te whakakā waea K1, kei te wahanga kōaro te putanga transistor ec I te wa i te "OFF" te whakakā waea K1, kei te wa noa te putanga transistor ec I te wa kei te "ON" te K2, ka tohua e te taiawhio te mahi whakaoho tohu rama whero |
| Te tohu mahi whakaoho marama | Naianei urunga mara>7mA, whakaoho iahiko-poto (SC), naianei whakaurunga kei runga i te pae |
| Te maha o te whakauru me te whakaputa | 1 whakauru 2 putanga |
| Nga taputapu mara e tika ana | Ko te whakapiri maroke, te whakawhiti tata NAMUR ranei i runga i te paerewa DIN 19234. |
| Tawhā pāmahana | Te pāmahana mahi: -20 ℃ ~ + 60 ℃, te pāmahana rokiroki: -40 ℃ ~ + 80 ℃ |
| Te haumākū o te hau | 10% ~ 95% RH me te kore te toha |
| Te kaha dielectric | I waenga i te taha haumaru me te taha haumaru-kore (≥ 3000VAC/min); i waenga i te tuku hiko me te tauranga haumaru-kore (≥ 1500VAC/min) |
| Te parenga whakaahuru | ≥100MΩ (i waenganui i te tāuru / putanga / tuku hiko) |
