Easy integration of Danfoss VLT frequency inverters

Would you like to connect Danfoss frequency inverters from the VLT series to AS-Interface? Simply by plug-and-play via their standard RS485 interface? Then use our ASi-5 motor module BWU4980. Simply connect the module with the two wires to the RS485 terminals in the Danfoss VLT frequency inverter, and you're done. Thanks to ASi, the power supply and communication of the module is carried out via a single cable.



One Ethernet node for more than 100 frequency inverters

Fig.: More than 100 Danfoss VLT frequency inverters (e.g.,VLT® AQUA Drive FC 202, VLT® AutomationDrive FC 301/FC 302, VLT® Decentral Drive FCD 302, VLT® Midi Drive FC 280, VLT® HVAC Basic Drive FC 101) can be efficiently wired on just one Ethernet node.
