Product Description:
The EL6751-1005 is a communication terminal manufactured by Beckhoff within the EL EtherCAT Terminals series. The unit functions as a CANopen interface that allows an EtherCAT controller to oversee external CAN networks, providing a gateway for distributed sensors and actuators used in automated machines. This arrangement lets one control platform exchange data with CANopen devices without adding a separate standalone gateway.
Its bus connector is a D-Sub, 9-pin socket, a physical layout chosen for secure shielding and quick attachment of standard CAN cables. Status LEDs on the housing supply immediate diagnostic feedback for run and error conditions. The terminal offers one communication channel and can be configured as master, manager, or slave to fit mixed topologies. The supported fieldbus protocol is CANopen, enabling standardized device profiles for sensors, drives, and I/O modules. Up to 127 downstream nodes may be addressed, allowing sizable sub-networks on a single terminal. Control electronics draw 230 mA from the EtherCAT E-bus, so the system power feed must account for this load. Galvanic isolation of 500 V separates the CAN side from internal logic, which helps reduce ground-loop effects and improves noise immunity.
Its enclosure carries a protection rating of IP20, making it suitable for cabinets where no liquid exposure is expected. Compact proportions of 24 mm x 100 mm x 52 mm conserve rail space while still leaving room for airflow. The housing snaps onto a 35 mm DIN rail, and the installation position can be horizontal or vertical. Polycarbonate construction provides electrical insulation and resists common workshop chemicals. Field conductors are landed through front-facing push-in terminals, allowing solid or ferruled wires to be inserted without tools and maintaining consistent contact force under vibration.
