ABB AI880A 3BSE039293R1 Mojule wa Kenyo ya Analoge e Phahameng
AI880A High Integrity Analog Input Module e etselitsoe hore ho be le tlhophiso e le 'ngoe le e sa hlokahaleng. Mojule o na le likanale tse 8 tsa hona joale tsa ho kenya. Ho hanyetsa ho kenya ke 250 ohm.
Mojule o aba phepelo ea transmitter ea kantle ho mocha ka mong. Sena se eketsa khokahano e bonolo ho aba phepelo ho li-transmitters tsa terata tse 2 kapa tse 3. Matla a transmitter a laoloa mme hona joale a na le moeli. Likanale tse robeli li qheletsoe ka thoko ho ModuleBus ka sehlopha se le seng. Matla ho Module a hlahisoa ho 24 V ho ModuleBus.
AI880A e lumellana le khothaletso ea NAMUR NE43, 'me e ts'ehetsa meeli e ka lokisoang ho feta le ka tlase ho mefuta.

Lipotso tse atisang ho botsoa ka sehlahisoa ke tse latelang:
-ABB AI845 ke eng?
ABB AI845 ke mojule oa ho kenya analog o fetolelang matšoao a analog ho data ea dijithale eo sistimi ea taolo e ka e sebetsanang. Hangata e sebelisoa ho hokahanya le li-sensor le lisebelisoa tse hlahisang matšoao a analog, joalo ka li-sensors tsa mocheso (RTDs, thermocouples), li-transmitters tsa khatello, le lisebelisoa tse ling tse amanang le ts'ebetso.
-Ke mefuta efe ea lipontšo tsa ho kenya e ka sebetsanang le module ea AI845?
Lipontšo tsa hona joale (4-20 mA, 0-20 mA).
Voltage (0-10 V, ± 10 V, 0-5 V, joalo-joalo) lipontšo
Resistance (RTDs, thermistors), ka tšehetso ea mefuta e itseng e kang 2, 3, kapa 4-wire RTDs
Thermocouples (e nang le matšeliso a batang a batang le linearization)
-Litlhoko tsa matla bakeng sa AI845 ke life?
AI845 e hloka phepelo ea motlakase ea 24V DC hore e sebetse.
