XB-EC-12 ctrlX I/O EtherCAT Extension Module

📦 Product Overview: ctrlX I/O XB-EC-12

The XB-EC-12 is a specialized interface module within the ctrlX I/O system designed to extend the local EtherCAT bus. Its primary function is to provide an external RJ45 port that allows for the continuation of an EtherCAT network to another I/O station or a third-party EtherCAT device. This makes it an essential component for distributed automation architectures where I/O modules are spread across different cabinets or machine sections.

🔹 1. Description

The XB-EC-12 (Material Number: R911400262) acts as an EtherCAT junction or branch terminal. It converts the internal LVDS (Low-Voltage Differential Signaling) backplane communication of a ctrlX I/O station back into standard Ethernet physical layer signals via an RJ45 socket. This allows for a flexible topology, enabling users to move from a standard linear structure into a star or tree topology depending on the network master's capabilities.

🔹 2. Key Functions

🚀 EtherCAT Extension: Allows for the connection of further EtherCAT slaves (additional I/O stations, drives, or sensors) via standard industrial Ethernet cables.

📡 Topology Versatility: Enables the creation of branches in an EtherCAT network, which is particularly useful for modular machine builds.

🛠️ Compact Design: Fits seamlessly into the ctrlX I/O lineup with a slim 20mm housing, maintaining consistent aesthetics and mechanical installation.

🛡️ Intelligent Processing: The module automatically detects the connection of a subsequent participant and activates the EtherCAT port accordingly.

💾 Visual Diagnostics: Features integrated LED indicators for Link and Activity status directly on the RJ45 port for easy on-site troubleshooting.

🔹 3. System Integration

📏 Installation: Snap-on mounting to a 35mm DIN rail. It must be placed at the right-hand end of a ctrlX I/O block or at the specific point where a network branch is required.

🔗 Power Supply: Draws its logic power from the internal bus system (UL), so no additional external wiring is required for the module's core operation.

⚙️ Configuration: Handled via the ctrlX I/O Engineering tool or any standard EtherCAT master configuration software using the appropriate ESI file.
