Basic Information
Brand:ABB
Model:NDBU-85
Origin:Sweden
Weight:Approximately 0.72 kg
Dimensions:Approximately 26.3 cm×9.5 cm×5.5 cm
Technical Parameters
Communication Speed:Supports 1 Mbit/s,5 Mbit/s,and 10 Mbit/s communication speeds.The DriveWindow default setting is 1 Mbit/s.
Optical Power:The optical power value can be adjusted based on the length of the fiber optic cable to ensure stable communication.Compatible Devices:DC drives(such as the DCS 600)use 10Mbd optical transmitters/receivers,while ACS 600 products use both 5Mbd and 10Mbd optical transmitters/receivers.5Mbd and 10Mbd components cannot be mixed.5Mbd optical components must be used only with plastic optical fiber(POF)cables.
Features
Branch Connections:As a branching unit,it enables branch connections for signals within the system,enabling multiple devices to communicate with the main system.
Strong Compatibility:Compatible with devices from the ACS 800 and DCS 800 series,suitable for a variety of industrial automation scenarios.
