Ultra-Compact Design for Space-Saving Installation:One of the smallest CPUs in the M238 series, ideal for space-constrained panels, compact machines, or embedded control systems.
Cost-Effective Entry-Level Controller:Among the most economical models in the series—delivers full PLC functionality (CPU + I/O + comms + display) at a low price point, reducing total system cost.
Integrated 16-Point Digital I/O for Simplified Wiring:Built-in 8 digital inputs + 8 transistor PNP outputs—meets basic logic control needs, reduces dependency on external modules, and simplifies wiring.
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.
