The Mitsubishi FX3U-16MT/ES is a compact and versatile Programmable Logic Controller (PLC) designed for small to medium automation tasks. Here’s a detailed breakdown of its features and specifications:

Model Breakdown:

• FX3U: Indicates the series, part of Mitsubishi’s advanced FX3U lineup with enhanced performance over older models (e.g., FX2N).

• 16: Total I/O points (8 inputs + 8 outputs).

• M: Denotes a “main unit” (standalone CPU with integrated I/O).

• T: Transistor output type (sink/source, DC loads).

• ES: AC power supply (100–240V AC, 50/60Hz).

Key Features:

1. I/O Configuration:

   • 8 Digital Inputs: 24V DC, typically with opto-isolation.

   • 8 Transistor Outputs: Sink/source type (supports DC loads, e.g., relays, solenoids).

     • Output Current: Up to 0.5A per point, 1.6A per common terminal.

     • High-Speed Switching: Suitable for pulse outputs (e.g., stepper/servo control).

2. Performance:

   • Processing Speed: 0.065µs per instruction (fast for small applications).

   • Memory: 64K steps of program memory, 4K data registers.

   • High-Speed Counters: Built-in for encoder input (e.g., up to 100kHz).

   • Pulse Outputs: Supports positioning control (e.g., 2-axis motion).

3. Power Supply:

   • AC Input: 100–240V AC, 50/60Hz (universal voltage range).

4. Expandability:

   • Expansion Modules: Connect additional I/O, analog, communication (e.g., FX3U-485ADP for RS-485), or special function modules.

   • Max Expansion: Up to 384 I/O points with extension units.

5. Communication:

   • Built-in Ports: RS-422 (programming) and USB (via FX-USB-AW adapter).

   • Protocols: Supports N:N Networking, MODBUS, and CC-Link via add-on modules.

6. Programming:

   • Software: GX Works2 or GX Developer (ladder logic, structured text).

   • Advanced Instructions: PID, matrix operations, and floating-point arithmetic.

Applications:

• Small Machinery: Packaging, conveyor systems.

• Motion Control: Stepper/servo motor positioning.

• Automated Systems: Sensor/actuator control, process automation.

Physical Specifications:

• Dimensions: 130mm (W) × 90mm (H) × 86mm (D).

• Mounting: DIN rail or panel-mounted.

Advantages:

• Compact Design: Ideal for space-constrained installations.

• Cost-Effective: Suitable for budget-conscious projects requiring reliable DC output.

• Flexibility: Expandable for future upgrades.

Limitations:

• AC Power Only: Not suitable for DC-powered systems.

• Limited Built-in I/O: Requires expansion for larger systems.

This PLC is a robust choice for applications demanding precision, speed, and scalability in a compact form factor. Always refer to the official Mitsubishi manual for wiring diagrams and detailed specifications.
