Lub AI880A High Integrity Analog Input Module yog tsim los rau kev teeb tsa ib leeg thiab rov ua dua.Lub module muaj 8 tam sim no input channels.Lub input tsis kam yog 250 ohm.
Lub module faib cov khoom xa tawm sab nraud rau txhua tus channel.Qhov no ntxiv kev sib txuas yooj yim los faib cov khoom siv rau 2- lossis 3-xaim transmitters.Lub zog transmitter yog saib xyuas thiab tam sim no txwv.Tag nrho yim channel raug cais tawm ntawm ModuleBus hauv ib pab pawg.Lub hwj chim rau Module yog tsim los ntawm 24 V ntawm ModuleBus.
AI880A ua raws li NAMUR cov lus pom zoo NE43, thiab txhawb kev teeb tsa ntau dhau- thiab qis dua qhov txwv.
