Mitsubishi Electric FX2N-80MT-ES/UL FX2N Series Micro PLC Base Unit

Description

Configured to deliver fast execution and dense local physical points, the Mitsubishi Electric FX2N-80MT-ES/UL serves as a high-density processing core within the FX2N micro PLC family. This unit integrates internal memory capacity, specialized high-speed counters, and dual-axis positioning outputs into a compact footprint. Designed for high-duty cycle industrial environments, it features a robust internal power supply and sink-logic transistor outputs suitable for driving interface relays, solenoids, and stepper/servo motor drives.

Product Features

• High-Density I/O Layout: Equipped with 40 digital inputs (24 VDC, Sink logic) and 40 digital outputs (Transistor, Sink logic) in a single modular base unit.
• Fast Logic Execution: Processes basic sequence instructions at 0.08 microseconds, ensuring precise real-time responsiveness for highly dynamic machine processes.
• Expandable Program Capacity: Features a standard 8000-step RAM memory (battery-backed) that can be expanded to 16000 steps using optional EEPROM or EPROM cassettes.
• Integrated Motion Controls: Provides two independent 20 kHz pulse train outputs (PLSY/PLSR instructions) for basic dual-axis positioning applications.
• Flexible Signal Terminations: Outfitted with removable M3 screw terminal blocks to allow rapid field pre-wiring and minimize downtime during maintenance cycles.

Applications

• Packaging and Labeling Machinery: Synchronizes continuous feed-rolls and quick-action cutting mechanisms using built-in high-speed counters.
• Multi-Axis Material Handling: Manages local conveyor routing, sorting systems, and small-scale gantry positioning coordinates.
• Automated Assembly Stations: Controls pneumatic actuators, monitors safety limit switches, and interfaces with indexing rotary tables.
• Specialized OEM Equipment: Operates as a standalone machine controller in commercial food processing, textile machines, and custom tooling units.

Alternative Models & Compatibility

When replacing legacy FX series systems, note that the FX2N-80MT-ES/UL is specifically configured for NPN/Sink inputs and NPN/Sink transistor outputs. For installations demanding source (PNP) logic output control, the alternative model FX2N-80MT-ESS/UL should be sourced to prevent mismatched polarity on field relay manifolds or servo inputs.

Application Pitfalls & Engineering Notes

Ensure that the total power drawn from the 24 VDC auxiliary service terminals does not exceed 460 mA. Overloading this channel will cause the internal power supply to enter over-current protection mode, causing intermittent system shutdowns. For extensive sensor networks, always route field sensor power through an independent, external 24 VDC industrial power supply with a common ground reference to the controller's 0V terminal.

Commissioning & Wiring Tips

When utilizing high-speed counters (up to 60 kHz) on inputs X000 through X007, route high-speed encoder signaling wires inside dedicated, shielded twisted-pair cables. Ground the shield at the PLC-side chassis terminal only. Avoid laying encoder cables parallel to high-current power lines or AC motor drive leads within the wire duct to prevent high-frequency noise from corrupting pulse counts.
