Product Description:
The EKM1101 EK EtherCAT Coupler is manufactured by Beckhoff, which ensures robust operations within tough industrial conditions while offering scalable network connectivity. This coupler is particularly made for simple integration into complex EtherCAT networks. This coupler utilizes a shielded Ethernet or EtherCAT cable with a minimum of Cat 5 for ensuring data transmission at high fidelity levels.
Supported by 100BASE-TX, the EKM1101 coupler can accommodate up to a maximum of 100 meters between stations, hence supporting extensive coverage in industrial environments. This coupler features a twin RJ45 interface and facilitates bus connections securely and directly. This coupler is also capable of operating with the EtherCAT protocol and features an average delay time of 1 µs, which ensures ultra-fast communication and propagation for real-time applications. This coupler’s data rate of 100 Mbit/s is appropriate for time-critical automation tasks. The use of a shielded medium also minimizes electromagnetic interference to enhance this coupler’s communication reliability. This coupler supports mounting on a 35 mm DIN rail as specified in EN 60715, and it can be installed in variable positions to support flexible cabinet layout and system architecture.
The EKM1101 is capable of addressing up to 4.2 GB peripheral I/O signal points to significantly increase the number of addressable field signals. This coupler also provides 256 programmable IDs in a 16 x 16 configuration to facilitate precise and organized device addressing within large systems. In terms of power design, the maximum power dissipation in this coupler is 20 W, which varies with the given load and converted electrical power. This coupler consumes 500 V DC electrical insulation between the peripheral voltage, the system voltage, and the EtherCAT signal to protect inner electronics from cross-interference and voltage spikes.
Frequently Asked Questions about EKM1101:
