ABB RETA-01 EtherNet Adapter — Compact Drive Network Interface
The RETA-01 from ABB adds an EtherNet port to ABB drives. It sits in the drive option slot. It speaks EtherNet/IP and Modbus/TCP. This lets a PLC or master station control the drive over Ethernet. The module carries a 34-pin parallel bus connector and an RJ-45 port. An 8-way DIP switch selects the intranet IP address. The control board supplies 380 mA at 5 V. The unit is IP20 rated and follows the drive’s own ambient limits. Its minimum estimated lifetime is 100 000 h. All materials are UL/CSA-approved. The RETA-01 meets EN 50081-2 and EN 50082-2 EMC standards. It is a practical choice for engineers who need EtherNet/IP on an ABB drive without extra gateways.

FAQ
Q: What is the main difference between RETA-01 and RETA-02?
A: RETA-01 supports EtherNet/IP and Modbus/TCP. RETA-02 supports Modbus/TCP and PROFINET IO. Pick based on your master protocol.
Q: How do I set the IP address on the RETA-01?
A: Use the 8-way DIP switch for the intranet address. Then finish network settings through drive parameters.
Q: Which cable type works best near drives and contactors?
A: Use CAT 5 STP or CAT 5 FTP. Both resist electrical noise better than plain UTP.
Q: Is a refurbished RETA-01 reliable?
A: Yes when tested. We verify each unit before shipment and cover it with a 12-month warranty.
Q: What should I check before buying?
A: Confirm drive option slot support, protocol needs, and cabinet space. Contact us for help.
