Expert Review

The FX2N-16MR-001 is a classic entry-level model in the FX2N series. With 8 inputs and 8 relay outputs, it is well suited for controlling motors, indicator lights, and contactors in small machines. The 0.08 μs instruction processing speed performs well among small PLCs. By adding expansion modules on the right side, I/O points can grow to 256, supporting future production line upgrades. The quick disconnect terminal block saves time during on-site maintenance.

Manager’s Insight

From a project perspective, this PLC offers excellent value. It connects directly to 220V mains power, eliminating the need for an additional power supply. The built-in 8K steps of memory handle most small to medium programs. If communication functions are needed later, adding a BD board provides RS-485 or RS-232 without replacing the main unit. Reliable and stable, it is a solid choice for long-term automation applications.

Typical Applications

• Small Packaging Equipment – Sealing machines, labeling machines, simple packing lines
• Conveyor Systems – Belt conveyors, sorting stop control
• HVAC Control – Fans, pumps, valve control
• Special Purpose Machines – Drilling machines, cutting machines, welding equipment
• Training & Education Platforms – PLC programming and logic control teaching

Frequently Asked Questions (FAQ)

• Does the FX2N-16MR-001 need a battery?
  The main unit uses RAM memory, so programs are lost after power loss. To retain programs, add an EEPROM cassette or a battery. An EEPROM cassette is recommended for maintenance-free operation.
• What load can the relay outputs handle?
  Each output handles up to 2A (250V AC or 30V DC). Suitable for contactors, solenoid valves, and indicator lights. Add a surge suppressor for inductive loads.
• Can it connect to an HMI?
  Yes. Add a BD board for RS-422 or RS-485 to connect to Mitsubishi or other brand HMIs. The programming port can also be used for communication.
• How do I add more I/O points?
  Connect FX2N series expansion modules to the right side of the main unit. Options include input modules, output modules, and mixed modules. Maximum I/O reaches 256 points.
• What are the purchase and delivery policies?
  A 12-month warranty covers non-artificial defects. Orders ship within 12-24 hours after payment. Shipping via FedEx, UPS, or DHL with tracking available worldwide.

Selection Guide

• Step 1 – Confirm I/O Count
  If your machine requires 8 inputs and 8 outputs or less, this model fits directly. Add expansion modules for more I/O points.
• Step 2 – Confirm Output Type
  Relay outputs suit AC loads or applications with low switching frequency. For high-speed pulse output to control servo or stepper motors, choose the transistor output model (MT).
• Step 3 – Confirm Communication Needs
  If communication with a host system or HMI is required, verify the needed interface (RS-232/RS-485) and select the appropriate BD board.
• Step 4 – Confirm Program Retention Method
  For program retention without a battery, select the EEPROM cassette to avoid regular battery replacement.
• Step 5 – Verify Stock & Lead Time
  Contact sales to confirm availability before ordering. Technical support is available for application questions.
