TM221CE24R belongs to Schneider Modicon M221 integrated programmable logic controller series, a core compact industrial PLC specially designed for small & medium automated machinery and distributed on-site control systems. Equipped with 14 digital inputs, 10 relay outputs and 2 built-in analog input channels, it adopts 256KB program & data memory to execute logic judgment, timing counting, motion positioning and signal interlock control. It collects field sensor switch signals and analog voltage data, drives solenoid valves, indicator lights, contactors and small loads via relay outputs. With Ethernet, Serial and USB multi communication ports, it realizes data upload, remote monitoring and program download. It supports expansion of TM3 series I/O modules to expand control points, widely used to build stable and miniaturized automation control solutions for standalone equipment and small production lines.
