Chotchinga chapayokha chachitetezo kumbali yodziwika: PHD-12TF-288, kuyika kwa digito ndi zotuluka, kulowetsa kamodzi ndi kutulutsa kawiri.
^ Chotchinga chakutali chingathe kusintha kusinthana kwapafupi ndi kulowetsamo kukhudzana ndi malo owopsa ku chizindikiro cha transistor ndikuchipereka kumalo otetezeka. The linanena bungwe transistor pakati pa ec okonzeka ndi kusankha lophimba wa "inverted gawo / wamba gawo" , Komanso, pali athandizira chizindikiro yochepa dera kapena lotseguka dera alamu chizindikiro, dera amapereka athandizira kachipangizo magetsi.
^ Chogulitsachi chimafuna magetsi akunja a 20-35VDC.
^ Chizindikiro cha chizindikirocho chimayikidwa mu kuwala kofiira ndi chikasu kuti chisonyeze momwe ntchitoyo ikugwiritsidwira ntchito, pamene ili yowopsya ndiye kuwala kumakhala kofiira, panthawi yogwira ntchito bwino kuwala kumakhala kwachikasu.
* Mphamvu zamabasi, chonde onani zowonjezera kuti mumve zambiri.
| Mphamvu yamagetsi | 20 ~ 35VDC, kugwiritsa ntchito mphamvu |
| Lowetsani chizindikiro | Sinthani cholumikizira / pafupi |
| Supply voltage from the sensor side on site | 8v ndi |
| Mawonekedwe a ma sign | Zolowetsa patsamba:> 2.1mA, zikutanthauza ON; Zomwe zalowa patsamba: |
| Kusintha kwa hysteresis: 0.2ms | |
| Mawonekedwe a Transistor | NPN mtundu transistor emitter kapena wokhometsa lotseguka dera linanena bungwe, galimoto mphamvu: linanena bungwe panopa ≤20mA (1.2KΩ), mkati pazipita panopa 100mA. Zokhala ndi chitetezo chanthawi yayitali |
| Kusintha kowongolera pakati pa gawo lotembenuzidwa ndi gawo labwinobwino lazotulutsa ec | Pamene dial switch K1 ili pa "ON", transistor linanena bungwe ec ali mu inverted gawo |
| Choyimba choyimba K1 chili pa "ZOZIMA", zotulutsa za transistor ec zili mu gawo labwinobwino | |
| Pamene K2 ili "ON", chigawocho chidzasankha alamu yowonetsera kuwala kofiira | |
| Kuwonetsa ntchito ya alarm yopepuka | Zolowetsa m'munda> 7mA, alamu yachidule (SC), malo olowera patsamba |
| Chiwerengero cha zolowetsa ndi zotuluka | 1 kulowetsa 2 kutulutsa |
| Zogwiritsidwa ntchito kumunda | Kuyanika kowuma kapena kusintha koyandikira kwa NAMUR molingana ndi muyezo wa DIN 19234. |
| Kutentha kwa parameter | Kutentha kwa ntchito: -20 ℃ ~ + 60 ℃, kutentha kosungira: -40 ℃ ~ + 80 ℃ |
| Chinyezi cha mpweya | 10% ~ 95% RH popanda condensation |
| Mphamvu ya dielectric | Pakati pa mbali yotetezedwa mwakuthupi ndi mbali yosakhala yotetezeka (≥ 3000VAC / min); pakati pa magetsi ndi ma terminal omwe si otetezeka kwenikweni (≥ 1500VAC/min) |
| Insulation resistance | ≥100MΩ (pakati pa zolowetsa/zotulutsa/magetsi) |
| Miyeso yakunja | Makulidwe 12.5mm x m'lifupi 108mm x mkulu 118mm |
| Kugwirizana kwa electromagnetic | Malinga ndi IEC 61326-1 (GB/T 18268), IEC 61326-3-1 |
| Chizindikiro chosaphulika | [Exia Ga]IIC |
| Chitsimikizo chachitetezo chogwira ntchito | SIL3 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 3-4) | Uwu = 250V Uo=10.5V Ine = 15mA Ko=1.7μF Lo=150mH Po=39.4mW |
| Zofunikira za malo oyika | Itha kulumikizidwa ndi zida za 0 zone ndi ⅡA, ⅡB, ⅡC mpweya wowopsa |
| Mtengo wa MTBF | ≤100000h |
