AO845 / AO845A Analog Output Module rau daim ntawv thov ib zaug lossis rov ua dua muaj 8 unipolar analog tso zis raws. Lub module ua tus kheej-diagnostic cyclically. Module diagnostics muaj xws li:
- Sab nraud Channel yuam kev tau tshaj tawm (tsuas yog tshaj tawm ntawm cov channel nquag) yog tias cov txheej txheem fais fab mov uas muab qhov hluav taws xob rau cov khoom siv hluav taws xob tsawg dhau, lossis cov zis tam sim no tsawg dua li qhov tso zis tawm tus nqi thiab cov khoom tso tawm tus nqi> 1 mA (qhib Circuit Court) .
- Internal Channel yuam kev raug tshaj tawm yog tias qhov tso zis hluav taws xob tsis tuaj yeem muab tus nqi tam sim no. Nyob rau hauv ib tug redundant khub lub module yuav raug txib kom yuam kev xeev los ntawm tus tswv ModuleBus.
- Module yuam kev yog qhia nyob rau hauv cov ntaub ntawv ntawm tso zis Transistor yuam kev, luv Circuit Court, Checksum yuam kev, Internal fais fab mov yuam kev, xwm txheej Link yuam kev, Watchdog los yog tsis ncaj ncees lawm OSP cwj pwm.
Nta thiab cov txiaj ntsig
- 8 channels ntawm 4...20 mA
- Rau ib daim ntawv thov los yog redundant
- 1 pawg ntawm 8 channel cais tawm hauv av
- Analog inputs yog luv Circuit Court ruaj ntseg rau ZP lossis +24 V
- HART hla kev sib txuas lus
