EK1501 Beckhoff EtherCAT Coupler With ID Switch 24VDC Terminal Modules Up To 65,534

1.Overview of the EK1501 Beckhoff

2.Core Features:

1. Core Tasks
Connect EtherCAT Terminals (ELxxxx) to a 100BASE-FX fiber optic network, enabling ultra-long-distance, interference-resistant distributed I/O stations.
Converts upper-layer Ethernet messages into E-bus signals, automatically mapping the complete process image without configuration.

2. Key Parameters

EMC: EN 61000-6-2 (Immunity) / EN 61000-6-4 (Emission)
Certifications: CE, UL, CCC, ATEX, IECEx
Ex Marking: II 3 G Ex ec IIC T4 Gc / Ex ec IIC T4 Gc, suitable for use in Zone 2 explosive gas environments

3. Main Features

20 km cascading of single-mode fiber, saving repeater and fiber optic cable costs
Hardware-based real-time forwarding with a period jitter of < 1 µs, enabling high-speed closed-loop control
Built-in 2 A E-bus power supply, capable of directly driving 30-40 standard digital terminals
3-digit ID dial for device grouping, quick location, and hot-swappable maintenance
Independent system/field power supply, supporting mixed-voltage I/O modules
Wide operating temperature, vibration resistance, and electromagnetic interference resistance make it suitable for demanding applications such as power generation, oil and gas, rail transit, and tunnels
Configuration-free plug-and-play: TwinCAT automatically identifies topology and terminal models, ensuring zero-programming during commissioning
EK1501 (multimode 2 km) and EK1501-0010 (single-mode 20 km) has the same parameters except for the fiber specifications and distance. Users can freely choose according to the wiring environment.

The EK1501 fiber optic coupler is suitable for a variety of industrial automation scenarios:

Widely distributed systems: These include wind farms and large production lines, where long-distance, interference-resistant communication is critical.

Environmentally sensitive to electromagnetic interference: Fiber optic communication is inherently immune to electromagnetic interference, making it suitable for use in environments such as high-voltage facilities and welding equipment.

Systems requiring flexible topologies: These include automated production lines requiring complex wiring configurations such as star and tree topologies.

Applications requiring high scalability: These include large machinery or process control systems requiring a large number of distributed I/O points.
