Description

Designed to handle complex control tasks in demanding industrial environments, the FX3U-128MT/ES-A functions as a high-performance, compact base controller within the Mitsubishi Electric MELSEC FX3U series. This main unit is equipped with a high density of integrated points, featuring 128 local I/O channels split evenly between digital inputs and transistor outputs. It features high-speed processing capabilities, an integrated real-time clock, and a large program capacity, making it suitable for high-speed positioning, machine synchronization, and advanced factory automation systems.

The unit operates on a wide-range AC power supply and can be seamlessly expanded to manage up to 384 I/O points when paired with modular extension blocks or special function adapters. High-speed counter inputs and three integrated pulse outputs provide built-in multi-axis positioning and motion control without requiring dedicated motion modules.

Features

  • 64 integrated 24 VDC digital inputs, configurable for sink or source wiring.
  • 64 integrated transistor (source) outputs, suitable for high-speed switching and interface routing.
  • Built-in 100-240 VAC wide-range power supply.
  • Integrated program memory of 64,000 steps EEPROM with slot expansion for optional memory cassettes.
  • Three independent, high-speed pulse outputs (up to 100 kHz) for direct servo and stepper motor control.
  • Expandable local configuration up to 256 I/O points, or up to 384 I/O points with CC-Link network integration.
  • Integrated serial communication interface with options for secondary RS-232, RS-485, or RS-422 adapter boards.
  • Integrated real-time clock and password-protected program access.

Applications

  • High-speed packaging and labeling machinery
  • Conveyor and material handling control systems
  • Multi-axis positioning and assembly equipment
  • Pumping, water treatment, and environmental control systems
  • Specialized textile and printing machinery

Installation Guidelines

To ensure reliable operation and thermal management, install the base unit horizontally on a flat surface or standard 35 mm DIN rail. Provide at least 50 mm of clearance space above and below the unit for adequate ventilation. Verify that the power supply wiring is connected to the designated L and N terminals, and ensure a dedicated Class D ground (100 Ohms or less ground resistance) is connected to the protective earth terminal. Route high-voltage AC power cables separately from low-voltage DC input/output signals to prevent electromagnetic interference.

What is the total I/O capacity of the FX3U-128MT/ES-A base controller?

The FX3U-128MT/ES-A features 128 integrated local I/O points (64 digital inputs and 64 transistor outputs) and is expandable up to 384 I/O points through extension blocks or network connection.

Are the digital inputs configured for sink or source logic?

The 64 integrated digital inputs are versatile and can be wired for either sink or source configuration depending on the external 24 VDC sensor wiring.

What is the output type used in this PLC unit?

The unit features 64 source-type transistor outputs, which are designed for high-speed switching and external interface connections.

Does this model support high-speed positioning tasks?

Yes, the FX3U-128MT/ES-A includes three integrated high-speed pulse outputs (up to 100 kHz) suitable for controlling servo drives and stepper motors directly.
