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.

Empirical Engineering Insights
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.
Installation Guidelines
CRITICAL WARNING
Isolate and lock out all AC mains power (100-240 VAC) feeding the controller before mounting or starting any wiring terminations. Work with insulated hand tools only. Verify that all terminal block retaining screws are securely tightened to prevent loose connections from causing thermal faults or arc damage.
1
Chassis Mounting: Install the main unit vertically onto a standard 35 mm DIN rail or bolt it securely using the integrated mounting brackets inside a well-ventilated, IP54-rated metal enclosure.
2
Ground Connection: Establish a dedicated low-resistance system ground path using a minimum of 2.0 mm² (14 AWG) wire connected directly to the protective earth terminal.
3
Input and Output Wiring: Strip the wire leads to a length of 6 mm, apply crimped bootlace ferrules, and insert them into the removable screw terminal blocks. Tighten the M3 terminal screws to a torque range of 0.5 to 0.8 N-m.
4
Pre-Power Inspection: Double-check all power supply connections on L and N before flipping the breaker. Power up the unit and verify that the "POWER" LED status light on the front panel remains solid green.
