AI895 Analog Input Module imatha kulumikizana mwachindunji ndi ma transmitters a 2-waya ndipo ndi kulumikizana kwina imatha kulumikizananso ndi ma transmitter 4 popanda kutaya mphamvu ya HART. AI895 Analog Input Module ili ndi mayendedwe 8. Gawoli limaphatikizapo zigawo zachitetezo cha Intrinsic Safety panjira iliyonse kuti zilumikizidwe kukonza zida m'malo owopsa popanda kufunikira kwa zida zina zakunja. Njira iliyonse imatha mphamvu ndikuwunika njira yotumizira mawaya awiri ndi kulumikizana kwa HART. Kutsika kwamagetsi komwe kumalowetsapo nthawi zambiri kumakhala 3 V, kuphatikizidwa ndi PTC. Ma transmitter pa tchanelo chilichonse amatha kupereka osachepera 15 V pa 20 mA loop pakali pano ku mphamvu zotumizira zovomerezeka za Ex ndipo amangokhala 23 mA pakudzaza. TU890 ndi TU891 Compact MTU itha kugwiritsidwa ntchito ndi gawoli ndipo imathandizira kulumikizana kwamawaya awiri pazida zopangira popanda ma terminals owonjezera. TU890 ya ma Ex applications ndi TU891 yamapulogalamu omwe si Ex.
Mbali ndi ubwino
• Makanema 8 a 4...20 mA, zolowetsa za unipolar zomaliza.
• Kuyankhulana kwa HART.
• Gulu limodzi la ma tchanelo asanu ndi atatu otalikirana kuchokera pansi.
• Mphamvu ndi kuwunika kwa Ex certified two-wire transmitters.
• Zolowetsa za analogi zosasunga mphamvu zamagwero akunja.
Ma MTU omwe amafanana ndi mankhwalawa
