Product Description:

The Beckhoff EL9570 EtherCAT Terminal represents an efficient and reliable component intended for industrial automation.

The terminal works at 48 V DC voltage and has a 500 µF capacitance to provide powerful energy storage capabilities. The terminal ensures stability during fluctuating load conditions through its 10 A maximum ripple current, which operates at 100 kHz. The EL9570 demonstrates efficiency in energy regeneration and braking functions because it has an internal resistance of < 20 mΩ at 100 kHz. The terminal works with a chopper voltage set above 56 V because this defines operations in dynamic braking or energy recovery applications. System protection during voltage spikes and fluctuations comes from an overvoltage control range that extends to ±2 V. The braking resistor operates with a 2-point control method that provides adaptive braking through a load-dependent clock rate. The EL9576 from Beckhoff serves as the recommended replacement for new projects because it provides enhanced performance features for contemporary systems.

The EL9570 utilizes electrolytic capacitors to store energy efficiently while its built-in ESD protection component reaches 2 kV to boost terminal resistance to electrostatic discharges. This compact and lightweight terminal, with its 90 g weight, fits seamlessly into different industrial control systems because of its small physical form. The product functions from 0° C to 55° C of environmental temperature and accepts storage at temperatures between -25° C and +85° C, which ensures proper performance in a variety of industrial zones. The terminal ensures compliance with several global standards, including CE, CCC, ATEX, and IECEx, because of its certifications, which allow it to function in safety-critical hazardous environments. It can be purchased at Wake Industrial with a one-year warranty.
