FX1N-60MR-001 Mitsubishi FX1N PLC Base Unit

Description

3. Key Technical Specifications

4. Product Introduction & Supply Chain Strategy

The Mitsubishi FX1N-60MR-001 is a compact PLC main unit engineered for small-to-medium industrial control applications, including packaging lines, material handling conveyors, and dedicated machine automation. Plant engineers depend on this controller for its high digital channel density, built-in high-speed counting capabilities, and reliable relay output switching for inductive AC/DC loads.

Because Mitsubishi has formally transitioned the FX1N line to End-of-Life (EOL) status, securing this specific unit as New Surplus provides a crucial operational buffer. Swapping a failed CPU with an unverified, worn refurbished unit risks immediate backplane faults, compromised memory retention, and worn output relay contacts. Maintaining genuine factory-sealed stock guarantees full internal relay lifespan, zero terminal screw degradation, and zero downtime while avoiding costly control panel re-engineering to newer FX3U or FX5U platforms.

5. Installation & Configuration Guide

Stage 1: Pre-Installation (Prep & Safety)

1. Enforce Lock-Out/Tag-Out (LOTO) procedures on the main 100–240V AC power distribution breaker feeding the target panel.
2. Put on an anti-static wrist strap anchored to a verified earth ground terminal.
3. Take high-resolution photos of all terminal block wiring and record expansion module alignment sequences before pulling the old unit.

Stage 2: Removal

1. Unplug the 8-pin mini-DIN programming cable and any attached BD extension boards or memory cassettes.
2. Disconnect all screw-terminal blocks or loosen individual terminal screws to release input, output, and power wiring harness leads.
3. Disengage the DIN-rail mounting clip at the bottom of the module housing and lift the main unit off the rail.

Stage 3: Installation (Clone & Seat)

1. Mount the FX1N-60MR-001 onto the DIN rail, pressing firmly until the mounting clip locks securely into place.
2. Reconnect any right-side expansion bus cables and re-seat optional top-mounted communication/analog BD boards.
3. Reattach wiring strictly according to the terminal map taken in Stage 1, ensuring 24 V DC sensor power polarities and AC line connections match OEM specifications.

Stage 4: Power-On & Testing

1. Verify AC line voltage measures between 100 V AC and 240 V AC before applying power.
2. Move the run/stop toggle switch on the PLC front panel to the STOP position.
3. Apply power and verify the POWER LED lights solid green without the BATT.V or ERROR LEDs illuminating red.
4. Download the ladder logic program via GX Developer or GX Works2 and toggle the switch to RUN. Confirm normal input/output LED activity.

6. Firmware/Software Versions & Upgrade Notes

• Software Compatibility: Fully compatible with Mitsubishi GX Developer (V7.0 and higher) and GX Works2 (V1.00 and higher).
• Memory Cassette Handling: If transferring a program via an external FX1N-EEPROM-8K cassette, always insert or remove the cassette while the PLC is completely powered off to prevent EEPROM corruption.
• Migration & Upgrade Caution: When converting ladder logic from an older -60MR-001 to a newer FX3U series replacement, review device memory maps (such as timers, counters, and auxiliary relays). Certain special data registers (D8000 series) differ across generations and require remapping before live execution.

7. Frequently Asked Questions (FAQ)

Q: Is this -60MR-001 unit brand new or pulled from an old production line?

This module is 100% genuine New Surplus stock. It has never been installed in an operational panel, never deployed on a plant floor, and is not a refurbished board. It remains in original factory packaging.

Q: Why pay a premium for New Surplus when cheaper refurbished controllers exist?

Refurbished PLC units often feature mechanically degraded internal relays, dried-out filtering capacitors, and worn terminal threads. Purchasing verified New Surplus guarantees 100% remaining relay contact life (rated for ~200,000 operations under full load) and eliminates unexpected downtime caused by internal component wear.

Q: The series is obsolete. How does having this spare help my facility?

Holding a factory-sealed -60MR-001 on-site acts as an immediate drop-in replacement policy. It prevents days or weeks of unscheduled downtime caused by sourcing rare legacy parts or spending thousands of dollars rewriting logic for newer PLC hardware formats.

Q: Can I use this relay output model to directly drive high-frequency pulse outputs?

No. The -MR model uses mechanical relay outputs, which are limited to slow switching speeds (~10 Hz maximum) to prevent premature contact burn-out. For high-speed pulse train outputs (e.g., driving stepper or servo drives), you must use a transistor output model like the -60MT.

Q: What warranty coverage comes with this module?

We back our Surplus PLC base units with a comprehensive 1-year replacement warranty. If the module exhibits any functional defects or hardware errors upon installation, we swap it directly from our warehouse inventory.
