Product Description:

A component of the KL Analog Input Modules, the Beckhoff KL9570 operates at a nominal voltage of 50 V.

It also has 500 µF of capacitance to stabilize system voltage while preventing electrical losses. The module shows excellence in energy storage for both peak usage periods and braking situations, which makes it necessary for motion control systems and dynamic loading applications. The KL9570 offers strong electrical performance through its specifications of 10 A maximum ripple current at 100 kHz and less than 20 mΩ internal resistance at the same frequency to provide optimal energy buffering. Surge voltage protection integrated within the device protects connected electronic equipment from potential harmful overvoltage situations when the voltage exceeds 56 V. The ±2 V overvoltage control system manages the braking resistor clock rate through the 2-point control method, which adjusts according to load conditions to enhance system performance and energy efficiency. The ZB8110 constitutes the brake resistor recommendation for applications using this module. The module is appropriate for industrial applications because it weighs 65 grams while being durable and small.

The gadget retains storage readiness between -25°C and +85°C and operates correctly in temperatures between 0°C and 55°C. High vibration and shock resistance is demonstrated by this device, which also satisfies EN 60068-2-6 and EN 60068-2-27 requirements. To ensure interference-free operations, this module complies with EN 61000-6-2 and EN 61000-6-4 EMC requirements for immunity functions and emission control. K-bus can operate at relative humidity levels of up to 95% as long as there is no condensation, since it maintains an electrical separation from field potential rated at 1500 V. It can be purchased at Wake Industrial with a one-year warranty.
