Kuyika kwa Analogi

Mwachidule

Chotchinga chapayokha pachitetezo chodziwikiratu: PHD-11TD-21, kuyika kwa analogi ndi kutulutsa, kulowetsa kamodzi ndi kutulutsa kamodzi.

^ Chotchinga chokhacho chingathe kudzipatula ndikutumiza chizindikiro cha 4 ~ 20mA kapena DC 4 ~ 20 mA chizindikiro chopangidwa ndi chotumizira pamalo owopsa kupita kumalo otetezeka. Pamene transmitter ndi mawaya awiri kapena atatu-waya dongosolo, chotchinga chitetezo amapereka mphamvu kwa transmitter.

^ Chogulitsachi chimafuna magetsi akunja a 20-35VDC.

^ Chogulitsachi chimathandizira chizindikiro cha HART ndi alamu yodula.

* Zindikirani: Ngati mukufuna magawo ena amtunduwu, chonde lemberani thandizo lathu laukadaulo. Ngati zotulukazo ndi magawo ena, zimawonetsedwa ndi nambala 9, ndipo magawo enieni amawonetsedwa pambuyo pa nambala yachitsanzo.

^ Chitsanzo:kulowetsa 2-waya, 3-waya kapena 4-20mA, kutulutsa 2 ~ 10V.

^ Chitsanzo:PHD-11TD-29 (2-10V)

* Mphamvu zamabasi, onani zowonjezera kuti mumve zambiri.

PHD-12TD-211

Ma transmitter awiri kapena atatu kapena magwero apano / 4 ~ 20mA kutulutsa 1 kulowetsa 2 kutulutsa

Mwachidule

PHD-12TD-211 ndi chotchinga chakutali chodziwikiratu chomwe chimapangidwira kuti chizilowetsamo ndi kutulutsa kwa analogi.

PHD-22TD-2121

Ma transmitter awiri kapena atatu kapena magwero apano

/ 4 ~ 20mA kutulutsa 2 zolowetsa 2 zotuluka

Mwachidule

Chotchinga chapayokha chachitetezo kumbali yodziwika: PHD-22TD-2121, kulowetsa kwapawiri ndi kutulutsa kwapawiri ndi chizindikiro cha analogi.

Surge Protection Type Analogue Input Isolated Safety Barrier
PHD-11TD-21+ 1 zolowetsa ndi 1 kutulutsa
PHD-12TD-211+ 1 zolowetsa ndi 2 zotuluka

Zolowetsa: mawaya awiri kapena atatu kapena gwero lapano (chizindikiro cha digito cha HART)
Kutulutsa: 4 ~ 20mA (chizindikiro cha digito cha HART)
