All-in-One Controller with 32 Built-in Digital I/O Points:Integrated 16 digital inputs (DI) + 16 transistor PNP outputs (DO)—eliminates the need for additional I/O modules in most small machine applications, reducing system cost and wiring complexity.
Built-in 4-Channel Configurable Analog Inputs:Supports 0–10 V or 0/4–20 mA signals, compatible with common sensors (temperature, pressure, flow)—reduces the need for external analog modules and enhances system integration.
Dual Communication Interfaces with Industry-Standard Protocols:Equipped with 1 Ethernet port (10/100 Mbps) and 1 RS-485 port, supporting Modbus TCP, Modbus RTU, EtherNet/IP (with license), and CANopen Master—enables seamless connectivity with HMIs, SCADA systems, drives, and other devices.
Onboard Human-Machine Interface (HMI):Features a built-in 3-line text display and 5 navigation buttons, allowing local monitoring, parameter adjustment, and diagnostics without an external HMI—significantly improving commissioning and maintenance efficiency.
Hot-Swappable Expansion Capability:Supports up to 7 TM2 series I/O expansion modules mounted on the right side, with hot-swap support—enables easy upgrades or replacements without shutting down the system, minimizing downtime.
High-Performance Processor for Fast Response:Powered by a high-speed processor with fast scan cycles—ideal for real-time control applications such as packaging, sorting, and filling machines.
