It provides 16 built-in digital I/O points, including 8 inputs and 8 relay outputs, enabling control of both AC and DC loads without additional interface relays. Powered by 100–240 V AC, it can be connected directly to standard mains power. The TM221CE16R features fast input channels for high-speed counting, integrated serial communication ports for flexible connectivity, and a microSD card slot for program backup and data logging. Its modular design allows for expansion with Modicon TM3 I/O modules to accommodate growing system needs.
