ABB 3BSE071500R1 BC820K02 Na’urar Haɗa CEX-Bus

3BSE071500R1 BC820K02 yana raba CEX-Bus zuwa sassa guda biyu masu zaman kansu har zuwa tazarar mita 200 a tsakaninsu. Yana goyon bayan keɓaɓɓun hanyoyin sadarwa (redundant communication interfaces) da kuma cirewa/kunshewa yayin aiki (hot swap). Na’urar tana samun wuta daga mai sarrafawa ko kuma daga wutar waje 24V DC.

Tambayoyin Fasaha Masu Yawan Yi

Q1. Ina buƙatar wutar waje don tazarar igiya mai gajarta?
A1. A’a. Don tazara ƙasa da mita 50, CPU tana ba da wuta ga BC820 ta hanyar CEX-Bus. Yi amfani da wutar waje 24V idan tazara ta haura mita 50 ko kuma idan ana so a sami redundanci na wutar lantarki.

Q2. Zan iya amfani da igiyar CAT6 madaidaiciya ta yau da kullum don RCU Control Link?
A2. A’a. BC820 tana buƙatar igiyar crossover mai rufi da aka yi wayoyi T568A zuwa T568B. Igiyar madaidaiciya ba za ta yi aiki ba.

Q3. An amince da BC820 don wuraren haɗari Zone 1?
A3. A’a. BC820 tana da takardar shaidar cULus Class 1 Zone 2 kaɗai. Ba a ƙayyade ta don Zone 1 ba.
