EJ1100 - Beckhoff EtherCAT Plug-in Module

The Beckhoff EJ1100 EtherCAT Plug-in Module serves as a key component for linking EtherCAT plug-in modules (EJxxxx) to 100BASE-TX Industrial Ethernet networks. It features dual RJ45 interfaces and supports distances of up to 100 m using shielded Cat.5 cables, making it ideal for flexible plant layouts. With a high data transfer rate of 100 Mbit/s and a typical delay of only 1 µs, it ensures low-latency communication for time-critical automation processes. The unit is powered by 24 V DC (-15%/+20%) and supplies up to 2200 mA E-bus current, providing stable performance across multiple connected devices.

The EJ1100 is engineered for industrial reliability with 500 V electrical isolation between power contact, supply voltage, and EtherCAT signals. Its polycarbonate housing (44 x 66 x 55 mm) is designed for integration on signal distribution boards, featuring signal-specific mechanical coding for error-free installation. The module is certified to CE and UL standards, conforms to EMC immunity/emission norms (EN 61000-6-2/EN 61000-6-4), and meets vibration/shock resistance requirements per EN 60068-2-6/27. Operating across a temperature range of -25°C to +60°C, it offers dependable use even in demanding factory environments.

In real-world use, the Beckhoff EJ1100 EtherCAT Plug-in Module is commonly deployed in machine building, packaging systems, robotics, and modular control cabinets. Its plug-in design reduces wiring complexity, enabling faster system assembly and maintenance. Integration with TwinCAT makes setup straightforward, while diagnostic features ensure easy monitoring during operation. For engineers and automation designers, the EJ1100 provides a robust, future-ready solution that supports scalable and efficient control architectures, strengthening Beckhoff’s reputation for innovative industrial connectivity solutions.
