DI880 yog 16 channel 24 V dc digital input module rau kev teeb tsa ib zaug lossis rov ua dua. Lub input voltage ntau yog 18 mus rau 30 V dc thiab cov input tam sim no yog 7 mA ntawm 24 V dc Txhua qhov input channel muaj cov txwv tam sim no, EMC tiv thaiv Cheebtsam, input state indication LED thiab optical isolation barrier. Muaj ib qho tam sim no txwv transducer fais fab tso zis rau ib lub tswv yim. Qhov Sequence of Event Function (SOE) tuaj yeem sau cov xwm txheej nrog kev daws teeb meem ntawm 1 ms. Cov xwm txheej kab tuaj yeem muaj txog 512 x 16 txheej xwm. Lub luag haujlwm suav nrog Shutter lim rau kev tawm tsam ntawm cov xwm txheej tsis xav tau. SOE muaj nuj nqi tuaj yeem tshaj tawm cov xwm txheej hauv qab no hauv cov lus tshwm sim - Channel tus nqi, Queue tag nrho, Synchronization jitter, Tsis paub meej lub sijhawm, Shutter lim nquag thiab Channel yuam kev.
Nta thiab cov txiaj ntsig
- 16 raws rau 24 V dc inputs nrog tam sim no sinking
