Product Description

Beckhoff Automation is an engineering company that has been producing innovative solutions to improve industrial production and processing systems for more than three decades. The company has the finest group of production engineers and has developed a reliable production process that ensures that all its products meet international quality and safety standards. The EK1521-0000 is a 1-port EtherCAT junction with a multi-mode fiber-optic connection. This product is part of the EK EtherCAT Coupler series designed by the reputable Beckhoff company; it is designed to enable the configuration of EtherCAT star topologies using the 100BASE-FX glass fiber hardware. The combination of several units of this device can be used to establish a modular EtherCAT start hub.

The EK1521-0000 features an SC duplex socket, which, in conjunction with a compatible EtherCAT coupler, makes the conversion from 100BASE-TX to 100BASE-FX hardware possible. Also, the use of this product with the EK1521 coupler makes it possible to reach a distance of about 2 kilometers without any significant reduction in communication efficiency. Configuration is not required for the EK1521-0000 before use; also, the approximately measured delay for the product is about 1 microsecond. The housing of this product is a compact terminal housing with signal LEDs for diagnostic purposes; also, the housing material is polycarbonate, which is known for its high mechanical strength and lightweight.

The EK1521-0000 should be installed on a 35 millimeters DIN rail which conforms to EN 60715 with lock. The product also permits side-by-side mounting through the use of a doubling slot and key connection. The wiring of connection cables into the EK1521-0000 is done with a specific push-in connection. The total weight of this product is about 65 grams.
