Tirohanga
Ko te whakakoi i te whakawhiti i te whakawhiti whakawhiti tohu whakaputa ka huri i te tohu whakauru o te whakapiri whakawhiti, te whakawhiti tata ranei ki te putanga whakawhiti ma te wehe. Ka kitea nga hapa o te raina ma te whakaputanga rei motuhake (he kowhiringa) ka whakaatuhia ma nga rama rama i runga ake o te waahanga. Ka whakamahia te whakahuri o te kōwae ki te whiriwhiri i te wahanga o te hongere me te mea e hiahiatia ana te mahi kimi hapa raina.
Me whakakaha motuhake tenei hua, ka wehea te tuku hiko, te whakaurunga me te putanga.
Whakatakotoranga
| Whakauru | |
| Tohu whakauru | Whakawhiti hoapā/whakawhiti tata |
| Te ngaohiko tuku o te pūoko | Mo te 8V |
| Awhe auau whakauru | ≤5kHz |
| Ngā āhuatanga tāuru/putanga: | |
| I runga i te waahi whakauru o naianei | > 2.1mA, kua katia te putanga, e tohu ana i te ON; Ina |
| Putanga ka tuwhera/katia noa te mana whakahuri ahua | 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 LFD rama whero |
| Putanga | |
| Tohu putanga | Transistor, rere whakaoho (he kowhiri) |
| Putanga huanga | NPN momo transistor emitter ranei kaikohi tuwhera iahiko putanga |
| Te kaha o te taraiwa | Putanga o nāianei ≤ 20mA (1.2k Ω), mōrahi o nāianei ā-roto 100mA, rite rawa ki te tiaki iahiko-poto o nāianei |
| Tawhā taketake | |
| Ngaohiko tuku | 20~35VDC |
| Kohi hiko | |
| tohu LED | Kakariki: Tohu hiko Kōwhai: Puta whakawhiti i roto i te ahua mahi noa Whero: Tohu LFD, whakaoho hapa raina |
| Tawhā pāmahana | Te pāmahana mahi: -20 ℃ ~ + 60 ℃, Te pāmahana rokiroki: -40 ℃ ~ + 80 ℃ |
| Te haumākū pātahi | 10% ~ 95% RH kore tōhau |
| Te kaha o te whakamatao | ≥2000VAC/min(i waenganui i te whakauru/putanga/putanga hiko) |

1. Ko te mana o te hiko hiko he mahi whiriwhiri. Me tohu nga kaiwhakamahi i te aratau tuku hiko ina ota. Tirohia te taapiri i te wharangi 89.
Raina Hapa Rapunga
Ka taea e nga kaiwhakamahi te kowhiri i te taha "ON" o te whakawhiti i te tihi o te waahanga kia taea ai te mahi rapunga he me te tohu i te whakaoho ma te rama rama whero. I runga i te waahi whakaurunga o naianei>7mA, whakaoho ara iahiko poto (SC); I runga i te waahi whakaurunga o naianei
