Product Description:

The EK1501 coupler links control components over extended spans using light-based pathways. It is created by Beckhoff and by producing remarkable products, the company continues to have an impact on the growth of industrial technology.

The EK1501 coupler operates within an EtherCAT communication framework by using a 100BASE-FX optical standard as its medium for data exchange. It works with multi-mode glass fiber with a core/cladding ratio of 50/125 µm by enabling optical transmission up to a maximum range of 2000 meters between network stations. It accommodates up to 4096 configurable Ids by supporting broad addressability in extended industrial networks. Electrical isolation is rated at 500 V by providing separation across power contacts, supply voltage and Ethernet segments which supports signal safety in varied working conditions. The unit has a mass of only 190 grams which aids in making it suitable for cabinet-mounted industrial automation applications where weight consideration is part of the system design. It can function in an ambient temperature range from -25°C to +60°C and can be stored within a broader range of -40°C to +85°C by allowing for easy transportation and non-operational periods. The protocol in use is EtherCAT which offers a deterministic and real-time capable transmission method.

The EK1501 coupler’s is minimal with an approximate internal delay of 1 microsecond. Data exchange is conducted at a steady rate of 100 Mbit/s by ensuring consistency in signal throughput. The physical interface consists of two SC Duplex ports for bidirectional communication. Installation is flexible with an IP20 protection grading and compatibility with variable positions within enclosures. Certifications and compliance markings for the EK1501 include CE, CCC, UL, ATEX, and IECEx which showcases deployment across multiple international markets and within environments requiring explosion prevention.
