The Beckhoff FC9004 Ethernet Card is a versatile 4-channel PCI network interface card designed to extend the connectivity of Beckhoff Industrial PCs in automation systems. With support for all Ethernet-based protocols and four independent 100BASE-T ports, the FC9004 provides engineers with a flexible and high-performance solution for managing multiple real-time communication tasks within one industrial PC.

Built on the IEEE 802.3 Ethernet standard, the card enables communication across a wide range of fieldbus systems, including EtherCAT, PROFINET, Ethernet/IP, and Modbus TCP. This universality ensures that the FC9004 can be deployed in mixed-protocol environments, making it highly suitable for both new installations and retrofit projects where multiple Ethernet systems need to coexist.

Each of the four Ethernet interfaces operates at 10/100 Mbit/s, offering sufficient bandwidth for deterministic real-time communication in demanding automation tasks. With support for cable lengths up to 100 m per port, the card provides the flexibility to connect devices across large production floors, distributed I/O systems, or modular machinery layouts.

The PCI interface ensures straightforward integration with Beckhoff Industrial PCs and other compatible systems. Once installed, the FC9004 works seamlessly with Beckhoff TwinCAT software, allowing engineers to configure communication parameters, assign ports to specific fieldbus protocols, and perform diagnostics directly from the control environment. This integration reduces setup time and enhances system transparency.

In terms of design, the FC9004 is built for industrial-grade reliability, supporting an operating temperature range of 0…55 °C. Its robust construction makes it suitable for deployment in machine automation, process control, packaging systems, and building automation—anywhere reliable Ethernet communication is required.

The card’s multi-channel design makes it particularly advantageous for applications requiring network segmentation or redundancy. For example, one port can be dedicated to EtherCAT I/O devices, another to supervisory control systems, and others to PROFINET or Ethernet/IP devices. This consolidation reduces the need for multiple separate NICs, simplifying system architecture and lowering hardware costs.

Typical use cases for the FC9004 include high-performance machine controllers, distributed EtherCAT networks, hybrid communication setups, and PC-based control systems where multiple Ethernet protocols must be supported simultaneously. Its ability to unify multiple communication roles within a single card makes it an indispensable tool for complex automation systems.

In summary, the Beckhoff FC9004 Ethernet Card provides four PCI-based Ethernet ports, universal protocol support, and industrial reliability in one compact solution. With its 10/100 Mbit/s capability, 100 m cable reach per channel, and seamless TwinCAT integration, it delivers the flexibility and performance needed to meet the communication demands of modern automation environments.
