Cost-Effective Entry-Level CPU:One of the most economical models in the Modicon M238 series—ideal for budget-sensitive applications requiring basic automation functionality, reducing total system cost.
Integrated 24-Point Digital I/O for Space & Wiring Savings:Built-in 16 digital inputs + 8 transistor PNP outputs—meets control needs of small machines without additional I/O modules, saving panel space and reducing wiring complexity.
Built-in 4-Channel Configurable Analog Inputs:Supports 0–10 V or 0/4–20 mA signals, directly connecting common sensors (temperature, pressure, level)—eliminates need for external analog modules and improves integration.
Onboard 3-Line Text Display & Navigation Buttons:Features a 3-line LCD display + 5 navigation keys—enables local monitoring, parameter setting, diagnostics, and scheduling without an external HMI—significantly lowering system cost.
Dual Communication Ports with Industry-Standard Protocols:Equipped with Ethernet + RS-485, supporting Modbus TCP, Modbus RTU, CANopen Master, and optional EtherNet/IP—ensures seamless connectivity with HMIs, drives, and SCADA systems.
Expandable with Up to 7 TM2 I/O Modules:Supports up to 7 TM2 series expansion modules on the right side—provides flexibility for future upgrades and more complex control requirements.
