AB Analogi RTD gawo 1756-IR6I

Allen-Bradley 1756-IR6I ndi gawo la analogi yoyezera kutentha.Iyi ndi gawo la analogi lomwe limagwiritsidwa ntchito ndi Resistance-Temperature Detectors (RTD).

Module ya 1756-IR6I imapereka mitundu iwiri ya data monga mawonekedwe ophatikizika ndi mawonekedwe oyandama.Posankha mtundu wamtundu uliwonse, zophatikizika zimakhala ndi magawo angapo olowetsa, zosefera, ndi zitsanzo zenizeni.Njira yoyandama imaphatikizapo zinthu zonsezi ndikuwonjezera kutentha, ma alarm, ma alarm, ndi kusefa kwa digito.Ilinso ndi gawo la kutentha losankhidwa kukhala Celsius kapena Fahrenheit.Pali Zinayi (4) zotheka athandizira ranges kwa gawo kuphatikizapo 1 mpaka 487 m?, 2 kuti 1000 m ?;4 mpaka 2000 m?;, ndi 8 mpaka 4000 m?;.Magawo awa amawonetsa ma siginecha ochepera komanso opitilira muyeso omwe angawoneke ndi module.Ili ndi zolowetsa zisanu ndi chimodzi (6) payekhapayekha za RTD komanso malingaliro a 16 bits.Kusintha kwenikweni kumaphatikizapo 7.7 m?bit kwa 1-487 Ohms;15 m?/bit kwa 2-1000 Ohms, 30 mKusefa kwa phokoso la sefa ya module ya notch.Onetsetsani kuti mwasankha zosefera zomwe zimagwirizana kwambiri ndi ma frequency akuyembekezeredwa a pulogalamuyo.Zosefera za digito zimasamutsa deta pochotsa zodutsa phokoso panjira iliyonse yolowetsa.
Chiwonetsero chanthawi yeniyeni cha 1756-IR6I chimalola ma module ambiri omwe adasonkhanitsa kuchokera pakusanthula njira zake zonse.Kuti mutsegule ma multicast, sinthani nthawi ya Real-Time Sampling (RTS) ndi nthawi yofunsira Packet Interval (RPI).

Zida zachitetezo zimaphatikizidwanso ndi gawoli monga kuzindikira kwapansi / kupitirira-kuchuluka, mawonekedwe a module omwe amagwiritsidwa ntchito poyang'anira ngati chizindikiro cholowa chikugwera kupyola malire omwe amaikidwa ndi zolembera.Ma alarm a ndondomeko amagwira ntchito mofananamo komabe malire a ndondomeko amaikidwa pamanja ndi wogwiritsa ntchito.Alamu yamtengo wophatikizika imalola gawoli kuti lizindikire kuchuluka kwachangu kapena kuchepa mkati mwa nthawi yochepa yodziwika.Ma alarm amangopezeka pamapulogalamu ogwiritsira ntchito poyandama.Kuzindikira kwa waya kumapereka kukwanira kwa mawaya a loop.Ikhoza kuzindikira ngati RTB kapena waya mu module yachotsedwa.

Zolakwa zazing'ono mu 10-ohm copper RTD zitha kulipidwa ndi gawo la 10 ohms offset gawo.Mitundu ya masensa imathanso kukhazikitsidwa panjira iliyonse mu gawoli.Izi zimayika chizindikiro cha analogi kukhala mtengo wa kutentha.

Allen-Bradley 1756-IR6I ndi gawo la ControlLogix lomwe limagwiritsidwa ntchito kulandira ma sign kuchokera ku Resistance Temperature Detectors (RTD).Gawoli ndi la gawo la analogi lolowera ndipo limagwiritsidwa ntchito makamaka poyezera Kutentha.

Imavomereza zizindikiro zotsutsa kuchokera ku mitundu ya RTD monga Platinum 100, 200, 500, 1000?, alpha=385;Platinum 100, 200, 500, 1000 ?Platinamu, alpha=3916;Nickel 120 ?, alpha=672, Nickel 100, 120, 200, 500 ?, alpha=618 ndi Copper 10 ?.Gawoli limagwira ntchito ndi 3-Waya ndi 4-Waya RTD.RTD imagwira ntchito popereka kukana kwapadera pa Kutentha kwapadera.Tebulo la RTD limagwiritsidwa ntchito kuzindikiritsa zomwe zikugwirizana ndi Resistance.Pogwiritsa ntchito gawoli, mtundu wa RTD wosankhidwa umasankhidwa kuti mugwire bwino ntchito.Kusankhidwa kumapangidwa pogwiritsa ntchito RSLogix 5000 kapena Studio 5000 Logix Designer Programming software.

Ma modules Lowetsani chizindikiro kwa kutembenuka kwa wosuta amasiyana malinga ndi mtundu womwe wafotokozedwa.Kwa 1 - 487 ?, Chizindikiro Chotsika ndi kutembenuka kwa ogwiritsa ntchito ndi 0.859068653?ndi -32768 amawerengera pomwe Chizindikiro Chapamwamba ndi kutembenuka kwa ogwiritsa ntchito ndi 507.862?ndi ma 32767.Kwa 2 - 1000 ?, 2?-32768 kuwerengera ndi 1016.502 ?Kuwerengera 32767, Kwa 4 - 2000?, 4?-32768 kuwerengera ndi 2033.780 ndi ?Zithunzi za 32767Pomaliza kwa 8 - 4020 ?, 8 ?- ndi mawerengedwe 32768 ndi 4068.392?ndi 32767 chiwerengero.

Kusamvana kwathunthu kwa gawoli ndi 16 Bits.Mumuyeso weniweni, izi zimamasulira ku 7.7 m?/bit kwa 1…487 ?;15m?/bit kwa 2…1000 ?;30m?/bit kwa 4…2000?ndi 60 m?/bit kwa 8…4020?.
