Hybrid Output Design: Transistor + Relay Outputs:Built-in 8 transistor PNP outputs + 8 dry-contact relay outputs—enables control of both high-speed digital loads (e.g., sensors, indicators) and high-current or AC loads (e.g., contactors, solenoids, small motors)—eliminates need for external relay modules.
Integrated 24-Point I/O for Space & Cost Savings:Total of 24 built-in I/O points: 16 DI + 8 PNP DO + 8 Relay DO—reduces dependency on external modules, saves panel space, and lowers total system cost.
Built-in 4-Channel Configurable Analog Inputs:Supports 0–10 V or 0/4–20 mA signals, directly connecting temperature, pressure, and flow sensors—ideal for process control without additional analog modules.
Dual Communication Ports with Industry-Standard Protocols:Equipped with Ethernet + RS-485, supporting Modbus TCP, Modbus RTU, CANopen Master, and optional EtherNet/IP—enables seamless integration with HMIs, drives, SCADA, and other controllers.
Onboard 3-Line Text Display & Navigation Buttons:Integrated 3-line LCD display + 5 navigation keys—allows local monitoring, parameter setting, scheduling, and diagnostics without an external HMI—reducing system cost and complexity.
Expandable with Up to 7 TM2 I/O Modules:Supports up to 7 TM2 series expansion modules on the right side—provides flexibility for system scalability and future upgrades.
