2. Key Selling Points

1. High-Performance Compact PLC Controller:The TM221CE24U belongs to the Modicon M221 series, a powerful and compact programmable logic controller (PLC) designed for small to medium-sized automation systems and standalone machine control, offering a cost-effective intelligent control solution.

2. Integrated 24 Digital I/O Points (Relay Outputs):Features 24 built-in digital I/O points, typically configured as 14 inputs + 10 relay outputs, ideal for medium-complexity control tasks such as packaging machines, material handling, and HVAC systems—reducing dependency on external modules and simplifying system architecture.

3. Relay Outputs for AC/DC Load Control:Equipped with relay outputs (24 V DC / 250 V AC, 2 A), capable of driving both DC and AC loads (e.g., contactors, solenoid valves, indicator lights, small motors), offering high drive capacity and electrical isolation—ideal for diverse industrial applications.

4. 24V DC Power Supply with Wide Voltage Range:Rated supply voltage is 24 V DC, with an operating range of 20.4–28.8 V, accommodating common power fluctuations in industrial environments for stable and reliable operation.

5. Built-in Ethernet Communication Port:Includes 1 Ethernet port (RJ45) supporting Modbus TCP, enabling seamless connectivity with HMIs, SCADA systems, supervisory computers, or cloud platforms for remote monitoring and data exchange.
