Product Description

The EJ1101 is an EtherCAT Coupler by Beckhoff that links the EtherCAT protocol at the fieldbus level with EtherCAT plug-in modules. This coupler features two external RJ45 sockets that facilitate flexible connections directly on the signal distribution board. The module supports a maximum distance of 100 meters between stations when utilizing the 100BASE-TX connection standard. This ensures reliable data transmission and maintains signal integrity over this distance. The coupler is designed to use industrial Ethernet/EtherCAT cables, with a minimum specification of Category 5 (Cat. 5). The use of shielded cables enhances protection against electromagnetic interference, ensuring high signal quality.

The EJ1101 coupler offers a typical delay of just 1 microsecond, ensuring rapid communication between connected devices. It supports data transfer rates of 100 Mbit/s, facilitating high-speed communication within the system. The module comes equipped with two external ID switches that allow for easy configuration and identification of individual modules within the EtherCAT network, supporting the implementation of customized setups tailored to specific application requirements. For enhanced reliability, the coupler is equipped with diagnostic capabilities that monitor for overvoltage and under-voltage conditions, providing real-time monitoring of power supply conditions.

The module offers versatile installation options, including control cabinet feed-throughs and housing installations. This flexibility allows for seamless integration into various system configurations. It is suited for -25°C to +60°C conditions, providing flexibility in operating environments. It also boasts a high tolerance for humidity of up to 95% but is susceptible to damage if exposed to moisture. With an IP 20 protection rating, the coupler is intended for installation in controlled settings, such as inside control cabinets, safeguarding it from dust and water ingress. Wake Industrial offers this Beckhoff controller module with a one year warranty.
