MX3G PLC + HMI All-in-One Controller

The MX3G PLC + HMI all-in-one controller is a compact industrial automation solution designed for users who need reliable PLC control with integrated touchscreen HMI functionality. Compatible with Mitsubishi-style programming environments such as GX Developer 8.86 and GXWorks2, this device offers strong flexibility for factory automation, machine control, and industrial monitoring applications.

One of the biggest strengths of this controller is its powerful 32-bit military-grade CPU, which delivers fast processing speeds and stable performance even in environments with high electromagnetic interference. This makes it suitable for demanding industrial applications where reliability is important.

The unit supports Ladder Diagram and SFC programming languages, making it accessible for technicians already familiar with Mitsubishi FX-series PLC systems. The included TPWorks HMI software adds convenient visualization and control options for operators.

Communication capabilities are another major advantage. The controller supports RS232, RS485, MODBUS, and Mitsubishi programming protocols, allowing easy integration with inverters, external HMIs, sensors, and other industrial equipment. The multiple programming ports, including Type-C connectivity, also improve convenience during setup and maintenance.

Performance features are impressive for this class of controller. It supports high-speed counting and pulse outputs up to 100KHz, making it suitable for motion control, encoder reading, and positioning systems. The analog expansion capability is also flexible, supporting multiple analog inputs and outputs with 12-bit precision.

The wiring design is practical and installer-friendly thanks to the 3.81 pitch pluggable terminals, which simplify installation and maintenance work. Users can also choose between transistor outputs, relay outputs, or mixed configurations depending on project requirements.

Security is another standout feature. The built-in 8-bit encryption system helps protect ladder logic programs from unauthorized access or copying, which is valuable for OEM machine manufacturers and industrial system integrators.
