EB/DNET-CXB

The backbone side of the EXTEND-A-BUS must adhere to standard ARCNET® cabling rules. Companion AI ARCNET active hubs are available for extending the backbone cabling. Hubs are cascaded to achieve the maximum distance: up to 6 km when using coaxial cabling and ten active hubs or up to 4.8 km when using a fiber optic backbone and two active hubs.

Features:

• Extends the length of DeviceNet™ networks up to 6 km
• Fully DeviceNet compliant
• Fiber optic or coaxial cabling
• Star, bus or distributed-star topology
• Variable data rates up to 500 kbps
• Low-voltage AC- or DC-powered
• Panel-mount or DIN-rail mount
