I/O expansion modules are electronic devices that increase the number of input and output (I/O) ports available to a sensor and controller system. They act as an intermediary between the main controller and additional sensors or actuators, enabling expanded functionality and control capabilities Applications of I/O Expansion Modules: Industrial automation: Expanding I/O capabilities for complex machinery, process control systems, and data acquisition applications. Building automation: Adding additional sensors and actuators for controlling lighting, HVAC systems, and security features in smart buildings. Robotics and automation: Enabling control of various sensors and actuators in robots, autonomous vehicles, and other automated systems. Data acquisition systems: Expanding data collection capabilities by connecting additional sensors for monitoring and analysis purposes. Medical devices: Increasing functionality in complex medical equipment like infusion pumps, ventilators, and diagnostic instruments. Benefits of Using I/O Expansion Modules: Increased functionality: Enables connection of more sensors and actuators, expanding the capabilities of your sensor and controller system. Improved scalability: Allows for modular system expansion by adding I/O modules as needed, adapting to changing requirements. Enhanced system flexibility: Provides greater control options and simplifies system configuration for diverse applications. Some of I/O products are
