ABB IMDSI22I/O总线扩展电缆GE Fanuc提供五条预布线I/O总线扩展线缆。下图中列出了这些电缆的目录号和长度。如果需要列出的电缆长度以外的电缆长度，则可以构建自定义电缆以满足应用的需要。有关电缆类型和连接器的详细信息，请参阅“电缆”一章。请注意，相同的电缆可以用于扩展和远程底板，但是远程扩展系统中使用的电缆必须使用“电缆”一章中所述的电缆类型。3英尺电缆（IC693CBL300）可以用作定制电缆和远程底板之间的Y形适配器。远程和扩展机架之间的区别基本上，远程机架提供与扩展机架相同的功能，ABB IMDSI22但具有更长的距离（扩展机架为700英尺/213米，扩展机架为50英尺/15米）。为了尽量减少不平衡的接地条件，远程底板具有额外的隔离电路。当系统彼此相距很远且不共享同一地面系统时，可能会出现不平衡的地面条件。ABB IMDSI22
英文资料
I/O Bus Expansion Cables Five prewired I/O Bus Expansion cables are available from GE Fanuc. Catalog numbers and lengths of these cables are listed in the following figure. You can build custom cables to suit the needs of your application if cable lengths other than those listed are required. Refer to the “Cables” chapter for detailed information on cable type and connectors. Note that the same cables can be used with both Expansion and Remote baseplates, however the cables used in a remote expansion system must use the cable type described in the “Cables” chapter.The 3 foot cable (IC693CBL300) can be used as a Wye adapter between custombuilt cables and Remote baseplates.Differences Between Remote and Expansion Racks Basically, Remote racks provide the same functionality as Expansion racks, but with the longer distance (700 feet/213 meters verses 50 feet/15 meters for Expansion racks) capability. To minimize unbalanced ground conditions, Remote baseplates have extra isolation circuitry. Unbalanced ground conditions can occur when systems are located long distances from each other and do not share the same ground system.ABB IMDSI22
