IIOT Enabled PLC based Elevator Control Application Training System

FEATURES

The PLC (Allen-Bradley/Siemens) system is equipped with 20 digital inputs, 12 digital outputs, 4 analog inputs, and 2 analog outputs, providing the necessary I/O capabilities for various industrial automation tasks. It also features Ethernet communication support, enabling seamless integration into industrial networks for remote monitoring, control, and diagnostics. The system comes with licensed PLC programming software, allowing users to program the PLC using standard languages such as ladder logic or structured text. It includes a 4-floor model designed for training purposes to observe the PLC and electromechanical applications together. The system is designed in a transparent structure to examine the mechanical and electronic systems. Real-world components like DC motors, limit switches, proximity sensors, toggle switches, selector switches, visual and audio indicators, relays, contactors, and voltage displays offer students hands-on, practical experience with equipment they might encounter in the field. The system also allows elevator process monitoring and control from anywhere using mobile devices and applications.
