Product Description:
The Beckhoff KS3403 belongs to KS Digital Input Modules for industrial uses.
This module enables detailed energy analysis through its three voltage and three current measurements, which support both energy control mechanisms and real-time machine performance monitoring needs. The KS3403 evaluates diverse electrical parameters from current through to power factor (cos φ), effective power, voltage peak values, and frequency, alongside energy monitoring and current peak measurements. With 500 V AC maximum voltage support, this measurement device offers 16-bit resolution processing (21-bit internal), which delivers an entire error range of 0.5% for current and voltage and 1% total. The module achieves accurate measurement results through true RMS processing of data sampled at a fast rate of 64,000 samples per second. The data gets refreshed every 50 milliseconds (customizable time) to provide systems controllers with real-time measurement feedback. The input resistance operates at a 500 kΩ voltage level and 33 mΩ current resistance to support diverse industrial measurement applications.
The K-bus maintains a strong electrical separation of 1500 V to both field potential and system components, thus assuring protection from interference while ensuring safety during operation. The process image of the module features 16-bit data values followed by 8-bit status inputs that operate in a configuration identical to its output data and control parameters to enhance Beckhoff’s automation architecture integration. The module possesses power-efficient operation from its 115 mA current usage and consists of dimensions measuring 12 mm x 100 mm x 68 mm for compact installation. The device achieves global approval through CE, UKCA, UL, and EAC standards to deliver accurate, high-speed energy monitoring and analysis features for industrial systems. It can be purchased at Wake Industrial with a one-year warranty.
