Chithunzi cha PH D-22T F-2727
Mwachidule
Chotchinga chapayokha chachitetezo kumbali yodziwika: PHD-22TF-2727, zolowetsa digito ndi zotuluka, zolowetsa ziwiri komanso zotulutsa ziwiri.
Chotchinga chodzipatula chimatha kutembenuza chosinthira choyandikira ndikulumikizana ndi malo owopsa kupita ku siginecha yolumikizirana ndi relay ndikutumiza kumalo otetezeka.
Cholumikizira chotulutsa chimakhala ndi chosinthira chosankha cha "ON/OFF". Kuphatikiza apo, pali cholumikizira cholumikizira chachifupi chozungulira kapena chotsegulira chozungulira, dera limapereka mphamvu kwa sensa yolowera.
Izi zimafuna magetsi akunja a 20-35VDC.
Chizindikiro cha chizindikirocho chimayikidwa mu kuwala kofiira ndi chikasu kuti zisonyeze momwe ntchitoyo ikugwiritsidwira ntchito, pamene ndi yowopsya ndiye kuwala kumakhala kofiira, panthawi yogwira ntchito nthawi zonse 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; zolowetsa pamalopo: |
| Kusintha kwa hysteresis: 0.2ms | |
| Relay linanena bungwe makhalidwe | Nthawi yoyankha: 20ms, kuyendetsa galimoto: 250VAC / 2A, 30VDC / 2A pansi pa katundu wotsutsa. |
| Linanena bungwe "ON"/"WOZIMA" kukhudzana kutembenuka ulamuliro | Pamene kuyimba kosinthira K1, K3 ili pa "ON" mbali, kutulutsa kwa relay ndi "WOZIMA". |
| Pamene kuyimba kosinthira K1, K3 ili pa "WOZIMA" mbali, kutulutsa kwa relay ndi "ON". | |
| Pamene dial switch K2, K4 ili pa "ON" mbali, dera limasankha kusonyeza red light relay alamu ntchito. | |
| Kuwonetsa ntchito ya alarm yopepuka | Zolowetsa pamalopo> 7mA, alamu yachifupifupi (SC), zolowetsa pamalopo |
| Kuti mulowetse ma switch, pomwe ntchito yozindikira kuti salumikizidwe ikufunika, choletsa cha 10KΩ chikuyenera kulumikizidwa mofananira malekezero onse a switch (Chonde onani cholumikizira II pazithunzi pansipa) | |
| Chiwerengero cha zolowetsa ndi zotuluka | 2 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 3-4,1-2) | 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 |
