Installation Guide

Follow these steps to install the FX2N-48MT-001 properly.

1. Mounting: Install the unit on a DIN rail or use M4 screws.

2. Spacing: Keep at least 50 mm space above and below.

3. Wiring: Use 0.75 to 1.5 mm² copper wires for terminals.

4. Grounding: Connect a dedicated ground with 100Ω or less.

5. Power Connection: Connect the L and N terminals to AC supply.

6. Input Wiring: Connect sensors to the input terminals X000 to X027.

7. Output Wiring: Connect loads to output terminals Y000 to Y027.

Do not run input wires in the same conduit as high-power cables. This prevents noise interference. Always turn off power before wiring the FX2N-48MT-001.

Frequently Asked Questions (FAQ)

1. Can the FX2N-48MT-001 replace an older FX2N-32MT unit?
Yes, the FX2N-48MT-001 offers more I/O points. It is backward compatible in programming. You may need to adjust the wiring layout.

2. What is the output current rating for each transistor point?
Each output point on the FX2N-48MT-001 handles 0.5 A. The total common terminal handles 0.8 A maximum.

3. Does this PLC support real-time clock functions?
No, the base FX2N-48MT-001 lacks a built-in clock. You need an optional FX2N-8AV-BD adapter for clock functions.

4. How do I connect a programming PC to this unit?
Use an FX-232AWC or FX-USB-AW cable. Connect to the built-in RS-422 programming port. Then use GX Developer or GX Works2 software.

5. What happens during a power failure to the FX2N-48MT-001?
The unit saves the current program and data to EEPROM. It automatically resumes operation when power returns. No data loss occurs.
