Analog Input

Overview

Isolated chengetedzo chipingamupinyi padivi rekuona: PHD-11TD-21, analogi yekupinda uye inobuda, imwe chete yekupinza uye imwechete kubuda.

^ Iyo yakasarudzika chipingamupinyi inogona kutsaura uye kutumira iyo 4 ~ 20mA siginecha kana DC 4 ~ 20 mA siginecha inogadzirwa neinotumira munzvimbo ine njodzi kunzvimbo yakachengeteka. Kana iyo transmitter iri maviri-waya kana matatu-waya sisitimu, iyo yekuchengetedza inodzivirira inopa simba kune inotapurirana.

^ Ichi chigadzirwa chinoda ekunze 20-35VDC magetsi.

^ Ichi chigadzirwa chinotsigira HART chiratidzo uye yekubvisa alarm.

* Ongorora: Kana iwe uchida mamwe ma parameter echigadzirwa ichi, ndapota taura nerutsigiro rwedu rwehunyanzvi. Kana iyo yakabuda iri mamwe ma parameter, inoratidzwa nenhamba 9, uye iyo chaiyo parameter inoratidzwa mushure memuenzaniso nhamba.

^ Muenzaniso:kuisa 2-waya, 3-waya kana 4-20mA, yakabuda 2~10V.

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

* Bhazi magetsi emagetsi, ona appendix yeruzivo.

PHD-12TD-211

Maviri kana matatu-waya transmitter kana yazvino sosi yekupinda / 4 ~ 20mA inobuda 1 yekuisa 2 kubuda

Overview

PHD-12TD-211 ndeye yakasarudzika yekuona yekupedzisira chengetedzo barriers yakagadzirirwa yakanangana neanalog yekupinza uye kubuda.

PHD-22TD-2121

Maviri kana matatu-waya transmitter kana ikozvino sosi yekupinda

/ 4 ~ 20mA inobuda 2 zvinopinza 2 zvabuda

Overview

Isolated chengetedzo chipingamupinyi padivi rekuona: PHD-22TD-2121, maviri maviri ekuisa uye maviri akabuda ane analogi chiratidzo.

Surge Dziviriro Type Analogue Input Isolated Safety Barrier
PHD-11TD-21+ 1 kuisa uye 1 kubuda
PHD-12TD-211+ 1 yekupinda uye 2 zvabuda

Kupinza: maviri kana matatu-waya transmitter kana ikozvino sosi (HART dhijitari chiratidzo)
Kubuda: 4 ~ 20mA (HART digitaalinen chiratidzo)
