Zotchinga zachitetezo zokhazikika mbali yodziwika: PHD-12HF-277, zolowetsa ndi kutulutsa kwa digito, zolowetsa ndi kutulutsa kamodzi ndi zotulutsa ziwiri.
Chotchinga chodzipatulacho chingasinthe chosinthira chapafupi ndi cholumikizira cholumikizira m'dera loopsa kukhala chizindikiro cholumikizirana ndi cholumikizira ndikuchitumiza kumalo otetezeka.
Chotulutsira chotulutsa chili ndi switch yosankha ya "ON/OFF". Kuphatikiza apo, pali chizindikiro cholowetsa chizindikiro cha short-circuit kapena open-circuit alarm, derali limapereka mphamvu kwa sensa yolowetsa.
Chogulitsachi chikufunika magetsi odziyimira pawokha.
Chizindikiro cha momwe chizindikirocho chilili chimayikidwa mu kuwala kofiira ndi kwachikasu kuti chisonyeze momwe chotulutsira chotulutsira chikuyendera, pamene chili choopsa ndiye kuti kuwalako kumakhala kofiira, panthawi yogwira ntchito bwino kuwalako kumakhala kwachikasu.
| Mphamvu yoperekera | 20~35VDC, kugwiritsa ntchito mphamvu |
| Chizindikiro cholowera | Ma switch olumikizana ndi switch kapena ma switch apafupi (NAMUR) |
| Mphamvu ya sensa pamalopo | 8V |
| Makhalidwe olowera chizindikiro | Mphamvu yolowera pamalo: >2.1mA, chizindikiro cha ON; Mphamvu yolowera pamalo: |
| Zotuluka m'malo otetezeka | Nthawi yoyankhira: 20ms, mphamvu yoyendetsa: 250VAC/2A, 30VDC/2A yolemera pang'ono |
Nthawi zambiri zotulutsa zimakhala “Zotseguka”/“Zotsekedwa” | Pamene chosinthira cha dial K1, K3 chili kumbali ya "ON", kutulutsa kwa relay kumakhala "OFF" |
| Pamene chosinthira cha dial K1, K3 chili kumbali ya "OFF", kutulutsa kwa relay kumakhala "ON" | |
| Pamene chosinthira cha dial K2, K4 chili kumbali ya "ON", dera limasankha kusonyeza ntchito ya alamu ya LFD yofiira | |
| LFD | Mphamvu yolowera pamalopo>7mA, alamu yofupikitsa dera (SC), mphamvu yolowera pamalopo |
| Pa cholumikizira cha switch, ngati ntchito yozindikira kulumikizidwa ikufunika, choletsa cha 22KΩ chiyenera kulumikizidwa motsatizana kumapeto onse a switch (Chonde onani cholumikizira cha switch II mu chithunzi cha waya pansipa) | |
| Chiwerengero cha zolowera ndi zotuluka | 1 yolowera 2 zotuluka |
| Zipangizo zogwirira ntchito kumunda | Chosinthira cholumikizira chouma kapena cholumikizira cha NAMUR motsatira muyezo wa DIN 19234 |
| Gawo la kutentha | Kutentha kogwira ntchito: -20℃~+60℃, kutentha kosungirako: -40℃~+80℃ |
| Chinyezi chocheperako | 10% ~ 95% RH palibe kuzizira |
| Mphamvu ya dielectric | Pakati pa mbali yotetezeka mkati ndi mbali yotetezeka mkati (≥3000VAC/min); pakati pa magetsi ndi malo osungira magetsi otetezedwa mkati (≥1500VAC/min) |
| Kukana kutchinjiriza | ≥100MΩ (pakati pa zolowetsa/zotulutsa/magetsi) |
| Miyeso | Kunenepa 15.8mm * m'lifupi 104.8mm * kutalika 116.1mm |
| Kugwirizana kwa maginito amagetsi | Malinga ndi IEC 61326-1 (GB/T 18268), IEC 61326-3-1 |
| Chizindikiro chosaphulika | [Exia Ga]IIC, [Exia Da]IIIC |
| Bungwe lopereka satifiketi | CQST (China National Quality Supervision and Test Centre for Explosion Protected Electrical Products) (Malo Oyang'anira ndi Kuyesa Ubwino wa Zamagetsi Otetezedwa ndi Kuphulika) |
| Ma parameter ovomerezeka (pakati pa ma terminal 1-2) | Um：250VAC/DC，Uo=10.5VDC，Io=14mA, Po=37mW,Co=2.4μF,Lo=165mH. |
| Zofunikira pa malo okhazikitsa | Ikhoza kulumikizidwa ndi zida zomwe zili mu 0 zone ndi ⅡA, ⅡB, ⅡC mpweya woopsa Yoyikidwa pamalo otetezeka, imatha kulumikizidwa ndi zida zachitetezo zamkati m'malo oopsa mpaka Zone 0, IIC, Zone 20, ndi IIIC. |
