Product Details

00-20-4A-C6-FE-1F is an industrial ethernet network card and reliable lan interface module marked with unique hardware MAC address, the OUI prefix 00-20-4A belongs to an industrial network vendor, widely fitted on PLC, motion controller, embedded IPC and field bus gateway. This industrial ethernet adapter establishes 10/100 Mbps Ethernet link to exchange real-time I/O data, setpoint values, alarm messages and diagnostic information between local control hardware and SCADA, HMI or upper host. It supports TCP/IP, Modbus TCP and other common industrial Ethernet protocols, with auto-negotiation and auto MDI/MDI-X function for convenient commissioning. Equipped with standard RJ45 port and link / activity LED indicators, technicians can quickly verify network connection status and locate communication faults. Designed with reinforced PCB, surge and ESD protection circuits, this ethernet network card can sustain stable transmission in environments with vibration, dust and electromagnetic interference on production floors. As a hard-to-source industrial spare, this lan interface module serves as a drop-in replacement to restore Ethernet communication for legacy automation controllers.

Supported Functions

This ethernet network card handles Ethernet packet sending and receiving for the host industrial controller. The lan interface module transmits discrete signals, analog process data and fault codes over Ethernet, and receives remote operator commands from supervisory systems. This industrial ethernet adapter supports static IP assignment, ARP, ping diagnostic and socket communication; it detects link loss and reports network failure to the main CPU. When communication is interrupted, it holds the last valid process data to avoid sudden disturbance to the running process. It works together with PLC, remote I/O racks and HMI panels to build an Ethernet-based distributed automation network.

Core Functions

As a dedicated LAN hardware interface, this ethernet network card provides physical Ethernet connectivity for legacy embedded controllers, converting internal parallel bus signals into standard Ethernet frames. Its unique fixed MAC address guarantees unambiguous node identification on plant network, which is critical for legacy system configuration and IP binding. This industrial ethernet adapter works as a direct spare to rebuild stable high-speed network communication for ageing automation equipment.
