EtherCAT I/O Module

EtherCAT I/O Modules for Industrial Real-Time Communication

An EtherCAT I/O module is a decentralized peripheral unit that transmits digital and analog signals from sensors and actuators to a central controller in real-time via the EtherCAT protocol. At IPC2U, you will find a wide selection of robust EtherCAT couplers and I/O terminals characterized by extremely low latency, simple wiring, and high noise immunity. Our modules enable high-precision data acquisition and control directly at the point of action, optimized for use in modern robotics and demanding mechanical engineering.

Scalable Peripherals for Your Automation Solution

In robotics, speed is everything. EtherCAT I/O modules form the bridge between the physical world and the digital control unit. Through decentralized installation in the field, you massively reduce wiring effort while simultaneously increasing signal quality.

  • Real-Time Performance: Benefit from cycle times in the sub-millisecond range – essential for synchronized motion sequences.

  • Modular Flexibility: Combine digital inputs (DI), digital outputs (DO), analog interfaces (AI/AO), as well as specialized modules for thermocouples or encoders.

  • Plug-and-Play Integration: Fast integration into existing EtherCAT networks thanks to ESI files (EtherCAT Slave Information) and standardized RJ45 cabling.

Robustness Meets Precision: EtherCAT in Harsh Environments

Our EtherCAT components have been specifically developed for industrial stresses. Whether in the control cabinet (IP20) or directly on the machine (IP67) – the galvanic isolation of the channels and the wide operating temperature range guarantee interference-free operation, even in environments with high electromagnetic loads from large motors or welding systems.

1. What are the advantages of EtherCAT compared to classic fieldbuses like PROFIBUS? 

EtherCAT uses the "processing on the fly" principle, where data packets are read and written while passing through the participants. This leads to nearly 100% bandwidth utilization and makes EtherCAT the fastest available Industrial Ethernet protocol for I/O applications.

2. Are the EtherCAT I/O modules from IPC2U compatible with masters from other manufacturers? 

Yes. Since we strictly adhere to the standard of the EtherCAT Technology Group (ETG), our modules are compatible with all common EtherCAT masters – whether you use a controller from Beckhoff (TwinCAT), CODESYS-based systems, or our own Intel x86 motion controllers.

3. How are the modules addressed in the network? 

EtherCAT modules do not require manual address assignment via DIP switches. Addressing occurs automatically through the physical position in the network (auto-increment) or via a unique device ID, which significantly simplifies commissioning and the replacement of modules.

4. Do the modules support "Hot Connect" for flexible machine concepts? 

Many of our EtherCAT solutions support Hot Connect functionalities. This allows parts of the system to be disconnected or added during ongoing operation, which is particularly important for modular robot cells and changing tool systems.
