Replacement & Compatibility FAQ
Q: Can FX3U-32MT replace FX2N-32MT directly?
A: Yes. The FX3U-32MT/ES is a direct upgrade with the same I/O count and mounting footprint. Program migration is straightforward using GX Works2.
Q: What is the difference between FX2N-32MT and FX2N-32MR?
A: The MT variant uses transistor (solid-state) outputs suitable for high-speed switching and DC loads. The MR variant uses relay outputs suitable for AC loads and higher current switching.
Q: Is the FX2N-32MT still in production?
A: The FX2N series has been phased out by Mitsubishi Electric. The FX3U/FX3G series are the recommended successors. Konmask.com maintains stock of genuine FX2N units for maintenance and replacement needs.
Q: Can I use a Delta DVP32ES200T as a replacement?
A: Functionally similar in I/O count and transistor output, but requires reprogramming in Delta’s WPLSoft/ISPSoft. Not a plug-and-play replacement — suitable for new installations only.
Q: What programming cable do I need?
A: Use the SC-09 RS-422 cable or USB-SC09-FX USB adapter for GX Developer / GX Works2 connection.
