We maintain a comprehensive lab stocked with actual industrial automation equipment. Multiple VFDs from 0.5HP to 10HP, several PLC models from different manufacturers, various HMI panels, and complete servo systems are available for hands-on practice. You do not watch demonstrations on a screen – you physically wire drives, program PLCs, design HMI screens, and troubleshoot real faults. This practical experience is what makes you job-ready from day one.
Brand-Neutral Comprehensive Training
Unlike brand-specific training centers that teach only one manufacturer’s products, we train you on equipment from all major brands. In real industrial work, you encounter Siemens today, Allen Bradley tomorrow, and Delta next week. Our multi-brand approach makes you versatile and employable anywhere. You learn the fundamental principles that apply across all brands, plus brand-specific features of each major manufacturer.
