PHD-11TD-21

Chidule

Chotchinga chachitetezo chodzipatula pambali yodziwira: PHD-11TD-21, cholowetsa ndi kutulutsa kwa analogi, cholowetsa chimodzi ndi chotulutsa chimodzi.

^ Chotchinga chodzipatulacho chingathe kusiyanitsa ndi kutumiza chizindikiro cha 4 ~ 20mA kapena chizindikiro cha DC 4 ~ 20 mA chopangidwa ndi chotumizira pamalo oopsa kupita kumalo otetezeka. Pamene chotumiziracho chili ndi waya ziwiri kapena waya zitatu, chotchinga chotetezeka chimapereka mphamvu kwa chotumiziracho.

^ Katunduyu amafunikira magetsi akunja a 20-35VDC.

^ Katunduyu amathandizira chizindikiro cha HART ndi alamu yochotsa ma alarm.

* Dziwani: Ngati mukufuna magawo ena a chinthuchi, chonde funsani chithandizo chathu chaukadaulo. Ngati zotsatira zake ndi magawo ena, zikuwonetsedwa ndi nambala 9, ndipo magawo enieniwo akuwonetsedwa pambuyo pa nambala ya chitsanzo.

Chotchinga chodzitetezera chodzipatula cha analog chimapereka mphamvu yodzipatulakupereka ma transmitter awiri ndi atatu m'malo oopsa.

Chizindikiro cha 4~20mA chopangidwa ndi chotumizira kapena gwero lamagetsi chimatumizidwa kuchokera kudera loopsa kupita ku gawo lotetezeka, motero chimayendetsa katunduyo m'dera lotetezeka. Pa ma transmitter awiri kapena atatu a waya kapena zizindikiro zamagetsi, chotchinga ichi chachitetezo chimathandizira kulumikizana kwa mbali ziwiri kwa chizindikiro cha digito cha Hart chomwe chili pamwamba pa chizindikiro cha 4~20mA ndipo chili ndi ntchito ya alamu yosweka ya waya.

Chogulitsachi chimafuna magetsi odziyimira pawokha, okhala ndi magetsi odziyimira pawokha, malo olowera, ndi malo otulutsira.
