Technical Overview of the EtherCAT Coupler
The FUJI FTT1604-G02 functions as a dedicated EtherCAT coupler module for distributed I/O systems. This component establishes the critical link between the EtherCAT fieldbus network and connected terminal devices. The module converts 100BASE-TX Ethernet telegrams into the internal signal representation for seamless data exchange. It enables real-time communication with minimal cycle times for time-critical automation tasks.

Communication Capabilities and System Integration
The module provides two RJ45 interfaces for network connectivity. One port connects the coupler to the master controller, and the other forwards communication to additional EtherCAT slaves. This design supports flexible line and star topology configurations for diverse system architectures. The FUJI FTT1604-G02 supports Distributed Clock (DC) synchronization with cycle times down to 125 µs for highly precise motion control applications.
Physical Characteristics and Installation
This coupler features a compact DIN-rail mounting design for standard industrial control cabinets. The module supports a wide input voltage range from 18 to 30 VDC with typical power consumption of approximately 2W. The device incorporates diagnostic LEDs that provide visual status indication for network activity, communication status, and system errors. The rugged enclosure meets IP20 protection standards and operates reliably across temperatures from 0 to 50°C.
