ABB NDCU-21C Precision Drive Control Unit for Industrial Automation

In stock

The ABB NDCU-21C is a robust network distribution and control unit designed for industrial automation. Key specs include: 24 VDC power supply, up to 8 Ethernet ports, and support for Modbus TCP/IP and PROFINET protocols. It’s commonly used in process control, power distribution, and manufacturing automation. Compared to the ABB NBRA-656C, the NDCU-21C offers more Ethernet ports but lacks the NBRA-656C’s built-in firewall. Unlike the ABB RINT-6611C, which focuses on remote I/O, the NDCU-21C provides broader network distribution capabilities.
