Ab Analog RTD Module 1756-IR6I

The Allen-Bradley 1756-Ir6i ndi njira yokwanira yoyeserera. Ichi ndi gawo lodziwika bwino lomwe limagwiritsidwa ntchito pokana matani oyang'ana masinthidwe (RTD).

Module ya 1756i imapereka mafomu awiri monga mawonekedwe a zigawo komanso njira yoyandama. Mukamasankha njira zophatikizira, mawonekedwe ophatikizidwa ndi magwiridwe osiyanasiyana amalowetsa, nosech zosefera, komanso zitsanzo za nthawi. Njira yoyandama imaphatikizapo zinthu zonsezi pogwiritsa ntchito kutentha kwa kutentha, ma alamu a ma alarm, owonjezera, komanso kusefera kwa digalo. Ilinso ndi malo ophatikizira kutentha monga Celsius kapena Fahrenheit. Pali magawo anayi (4) omwe angakhale nawo kwa gawo limodzi kuphatikiza 1 mpaka 487 m ?; 4 mpaka 2000 m?; Ndi 8000 m?;. Izi zimapangitsa zizindikiro zochepa komanso zokwanira zodziwika ndi gawo. Ili ndi sikisi (6) zonse zokhazokha za payekha komanso chisankho 16. Kusintha kwenikweni kumaphatikizapo 7.7 m? 15 m? / Pang'ono kwa 2-1000 ohms, 30 m? Kusefa kwa mzere wa nodule. Onetsetsani kuti mwasankha zosefera zomwe zikugwirizana kwambiri ndi zomwe akuyembekezera kuti agwiritse ntchito. Zosefera za digito zimachepetsa deta pochotsa phokoso pazomwe zimayambitsa njira iliyonse.
Mbali ya 176-IR6I imalola gawo lomwe limayambira nthawi zambiri zimasonkhanitsidwa kuchokera kuwunikira njira zake zonse zoyambitsa. Kuti muthandizire multicast, kukonzanso nthawi yeniyeni (RTS) ndi nthawi yofunsidwa (RPI) nthawi (RPI).

Zotetezedwazo zimaphatikizidwanso ndi gawo ili monga kupezeka kwapamwamba / zopitilira muyeso, gawo la gawo lomwe limagwiritsidwa ntchito kuwunika ngati sigiriki yopitilira muyeso. Njira ya ma arms imagwiranso ntchito mofananamo njira zomwe zimapangidwira zimaperekedwa ndi wogwiritsa ntchito. Alangizi ophatikizidwa amalola gawo lomwe lingawone kukula kapena kuchepa kwa nthawi yokhazikika. Voter Alamu imapezeka pokhapokha pogwiritsa ntchito malo oyandama. Waya wolumikizidwa ndi waya umapereka chiuno chokwanira. Itha kuzindikira ngati RTB kapena waya mu gawo lasambitsidwa.

Zolakwika zazing'ono zopweteka mu 10-Ohm Copper RTD imatha kulipidwa ndi gawo la 10 ohms yolumikizitsa. Mitundu ya sensor imatha kupangidwanso pa njira iliyonse yomwe ili mu gawo. Izi zimayang'ana chizindikiro cha analog kukhala mtengo kutentha.

The Allen-Bradley 1756-Ir6i ndi gawo laurlogix lomwe limagwiritsidwa ntchito kulandira zizindikiro chifukwa cha zojambulazo (RTD). Gawo ili ndi la gulu la analog ndipo limagwiritsidwa ntchito makamaka pakugwiritsa ntchito kutentha.

Zimavomereza zizindikiro zochokera ku mitundu ya RTD monga platinam 100, 200, 500, 1000? , alpha = 385; Platinamu 100, 200, 500, 1000? Platinamu, alpha = 3916; Nickel 120?, Alfa = Nickel 100, 120, 200, 500? , Alpha = 618 ndi mkuwa 10?. Gawoli limagwirizana ndi kugwiritsa ntchito waya ndi waya ndi waya ndi 4. Ntchito za RTD popereka zonena zina zomwe zimachitika pamoto wina. Tebulo la RTD limagwiritsidwa ntchito kuzindikira zotulutsa zogwirizana. Ndi kugwiritsa ntchito gawo ili, mtundu wosankhidwa wa RTD umasankhidwa kuti azigwira ntchito modekha. Kusankhidwa kumapangidwa pogwiritsa ntchito mapulogalamu a RSLOGX 5000 kapena Studio 5000 yolembetsa.

Ma module amathandizira kusanja kwa ogwiritsa ntchito kumasiyana motengera kuchuluka kofotokozedwa. Kwa 1 - 487? Ndipo -32768 ikuwerengedwa pomwe kutembenuka kwakukulu ndi kusatsegula ndi 507.862? ndi ziwerengero za 32767. Kwa 2 - 1000 ?, 2? -32668 ndi 1016.502? 327777 Chiwerengero, kwa 4 - 2000?, 4? -32668 ndi 2033.70 ndipo? 327777 ikuwerengedwa. Pomaliza kwa 8 - 4020?, 8? - Kodi kuwerengera 32768 ndi 4068.392? ndi ziwerengero 37777.

Kusintha konse kwa gawo ili ndi 16 nthambi. Muli muyeso weniweni, izi zimamasulira mpaka 7.7 m? / Pang'ono kwa 1 ... 487?; 15 m? / Pang'ono kwa 2 ... 1000?; 30 m? / Pang'ono kwa 4 ... 2000? ndi 60 m? / pang'ono kwa 8 ... 4020?.
