PHM-7530 Ex. Imojuli yokufaka ye-analog yamatjhaneli amathathu
Ukuhlolisisa umkhiqizo
Ingatjhugulula isignali yamanje yamatjhaneli amathathu endaweni eyingozi ehlukanisiweko ibe ziimpawu zedijithali, begodu ngokuya kwephrothokholi ye-MODBUS RTU inikela amasignali wedijithali ku-PHM7100, i-PLC nofana iinhlelo zekhomphyutha ezibambako.
Iinkomba zethekhnikhi
| Isisetjenziswa samandla | 20~35VDC |
| Ukukhipha kwamandla ngamandla anikelweko | Lokha isekhethi nayikhipha i-20mADC, ivoltheji enikelweko ingaphezu kwe-16VDC Input Two, three-wire system nofana i-DC 4~20mA DC |
| Faka | Isistimu yeentambo ezimbili, ezintathu nofana i-DC 4~20mA DC |
| Inembo | 0.1% |
| Isikhathi sokuphendula | ≤10ms |
| Inomboro yesiteshi | 3 amatjhaneli |
| Isisetjenziswa sokuthintana | RS485 |
| Iphrothokholi yokukhulumisana | I-MODBUS RTU |
| Amandla we-dielectric | ≥2500VAC (itheminali ephephileko nengaphephiko) |
| Ukujamelana nokuvikela | ≥100MΩ |
| Iinsetjenziswa ezisebenzako | Ama-transmitter amabili nofana amathathu anentambo nofana amatshwayo we-DC, umkhiqizo lo ungahlanganiswa nemikhiqizo evela kubakhiqizi abanengi (ABB, Fisher, Rosemount, Honewe11 kanye ithekhnoloji engeniswako 1151, i-EJA, i-SMAR neminye imikhiqizo) |
| Ipharamitha yokutjhisa | Izinga lokutjhisa lokusebenza eliragela phambili: -20°C~+60°C, izinga lokutjhisa lokugcina: -40°C~+85 |
| Umswakama womoya | 10%~95%RH ukungatjhuguluki |
| Isibonakaliso esivikela ukuqhuma | [Exia Ga] IIC |
| Imingcele yokuqinisekisa (hlangana namatheminali 1-2, 4-5 no-7-8) | Um=250V Uo=10.5V Io=15m Co=1.7μF Lo=100mH Po=39.4mW |
| Imingcele yokuqinisekisa (hlangana namatheminali 2-3, 5-6 kanye no-8-9) | Um=250V Uo=28V Io=93mA Co=0.05μF Lo=2.4mH Po=0.65mW |
| Iimfuneko zendawo yokufaka | Ingahlanganiswa namathulusi ase-0 zone nge-IIA, IIB, IIC igesi eyingozi |
Ubunjalo bomkhiqizo
- 1.Ukusetjenziswa kwamandla aphasi, ukutjhuguluka kwezinga lokutjhisa eliphasi, ukulinganisa okuzenzakalelayo.
- 2.Sekela iplagi etjhisako
- 3.Iphrothokholi yokukhulumisana ye-MODBUS RTU iyasekelwa, begodu izinga lokukhulumisana liphezulu ukuya ku-115200bps.
- 4.Sekela ukuphakelwa kwamandla nokukhulumisana ngeendlela ezimbili: isitimela sokufaka ngemuva kanye netheminali.
- 5.Ihlanganiswe isetjenziswa ne-PHM-7100 ukusekela i-MODBUS TCP/IP, ukwenzela bona kube lula ukufakwa nokugcinwa, begodu nokwenza ngcono ukusebenza kokudluliswa kwedatha.
