PHD-11TD-21

Dulmar Guud

Caqabadda badbaadada ee go'doonsan ee dhinaca ogaanshaha: PHD-11TD-21, gelinta iyo wax soo saarka analogga ah, gelinta hal iyo wax soo saar hal.

^ Caqabadda go'doonsan waxay go'doomin kartaa oo u gudbin kartaa calaamadda 4 ~ 20mA ama calaamadda DC 4 ~ 20 mA ee uu soo saaro gudbiyaha aagga khatarta ah aagga badbaadada leh. Marka gudbiyuhu yahay nidaam laba-silig ah ama saddex-silig ah, caqabda badbaadada ayaa siisa koronto gudbiyaha.

^ Badeecadani waxay u baahan tahay koronto dibadeed oo ah 20-35VDC.

^ Alaabtan waxay taageertaa calaamadda HART iyo digniinta goynta.

* Fiiro gaar ah: Haddii aad u baahan tahay xuduudo kale oo badeecadan ah, fadlan la xiriir taageeradayada farsamada. Haddii wax soo saarku yahay xuduudo kale, waxaa lagu tilmaamayaa lambarka 9, xuduudaha gaarka ahna waxaa lagu tilmaamayaa lambarka moodeelka ka dib.

Caqabadda badbaadada ee go'doonsan ee la geliyo ee analogga ah waxay bixisaa awood go'doon ahsahayda laba iyo saddex qalab gudbiye oo ku yaal meelaha khatarta ah.

Calaamadda 4 ~ 20mA ee uu soo saaro gudbiyaha ama isha hadda jirta waxaa laga gudbiyaa aagga khatarta ah una gudbiyaa wax soo saarka aagga badbaadada leh, taasoo keentay in culaysku ku socdo aagga badbaadada leh. Laba ama saddex gudbiye oo silig ah ama calaamadaha isha hadda jira, caqabaddan badbaadada waxay taageertaa isgaarsiinta laba-geesoodka ah ee calaamadda dijitaalka ah ee Hart ee ku dul taal calaamadda 4 ~ 20mA waxayna leedahay shaqo digniin ah oo jabaysa silig.

Badeecadani waxay u baahan tahay koronto madax-bannaan, oo leh koronto go'doonsan, gelinta, iyo terminaalka wax soo saarka.
