Product Description:
The EK EtherCAT Coupler EK1960-2608 is manufactured by Beckhoff and is a high-performance automation device used for fast communication and efficient control. This coupler offers a response time of ≤ 15 ms, normally 10 ms, for fast data communication via EtherCAT networks. This coupler features a maximum switching current (NO contact) of 8 A, which allows it to handle higher electrical loads.
The EK1960-2608 coupler features a release time of ≤ 5 ms, with a normal value of approx. 2 ms, for fast switching off of control signals to minimize switching delays. For general industrial use, this coupler can handle AC15 (230 VAC) applications with a continuous current of 3 A, which is suitable for relay-based as well as motor control applications. This coupler offers a low switching current of 10 mA minimum, with AgNi (silver-nickel) contacts, thereby providing reliability for low signal circuits. The switching capacity of this coupler complies with IEC/EN 60947-5-1, 250 VAC / 3 A for safety and compliance in controlled environments. The EK1960-2608 supports up to 20 switching cycles per second as its maximum switching frequency to enable high-speed actuation for applications where signals must change frequently.
This coupler’s EMC emission complies with EN 61000-6-4 to reduce electromagnetic interference in control cabinets. In terms of mechanical strength, this coupler meets EN 60068-2-6 vibration resistance for reliability under moving or vibrating installations. This EK EtherCAT Coupler EK1960-2608 has a protection rating of IP 20, as per IEC 60529, and is designed for indoor use, such as in switchgear cabins. This coupler weighs approximately 560 g to provide a balance between strength and its modular design. In terms of environmental durability, this coupler can be stored between the temperature ranges of -40 °C to +70 °C.
Frequently Asked Questions about EK1960-2608:
Q: Why does the EK1960-2608 use silver-nickel (AgNi) for contacts?
A: AgNi enhances electrical conductivity and durability, especially in high-frequency switching. It also reduces contact wear, improving long-term performance.
Q: How does the 20 switching cycles/sec frequency benefit system performance?
A: It allows rapid actuation of devices, ideal for systems requiring frequent signal updates. This minimizes latency in time-sensitive control operations.
Q: What role does EMC emission compliance (EN 61000-6-4) play in EK1960-2608?
A: It ensures the coupler does not interfere with nearby devices. This maintains communication reliability in densely packed control cabinets.
Q: How does the EK1960-2608 handle low current signals efficiently?
A: Its 10 mA minimum switching current allows it to detect and process weak signal levels. This is critical in sensor-based or low-voltage applications.
Q: Why is IP20 protection suitable for the EK1960-2608?
A: IP20 is appropriate for closed electrical enclosures, offering protection against touch and basic intrusion. It is not meant for open or wet environments.
