PHD-11TC-33*
Mwachidule
Chotchinga chapayokha chachitetezo pakutha kuzindikira: PHD-11TC-33 *, kulowetsa chizindikiro cholumikizirana, kulowetsa kamodzi ndi kutulutsa kamodzi. Chotchinga chachitetezo chimatha kuzindikira kulumikizana kwapawiri kwa ma siginecha amitundu iwiri ya digito pakati pa mawonekedwe a RS485 mdera lowopsa ndi mawonekedwe a RS485 m'malo otetezeka.
Izi zimafuna magetsi akunja a 20-35VDC.
Chogulitsacho chili ndi chizindikiro cha chizindikiro (chachikasu)
Mu kalata yachitsanzo: PHD-11C-33* munthu "*" akuyimira magetsi operekedwa, ndipo malamulo ndi awa:
| Kodi | Kupereka magetsi, magetsi |
| Ayi | Palibe mphamvu zoperekedwa |
| A | 5 V |
| B | 6v ndi |
| C | 12 V |
| F | 24v ndi |
| H | Wogwiritsa ntchito |
* magetsi okwerera mabasi, chonde onani zowonjezera kuti mumve zambiri.
