Mitsubishi MELSEC FX-series compact PLCs hold the largest installed base of any compact PLC platform in Malaysian manufacturing – established across automotive, F&B, rubber processing, semiconductor, and general automation between 1995 and 2026. Flextech provides FX2N (for installed base spare and expansion), FX3G (current generation mid-range), and FX3S (current generation entry compact) with genuine Mitsubishi Electric authentication and quotation within 24-48 hours from Puchong, Selangor.

FX-Series PLC Overview: Three Generations in Malaysian Plants

Mitsubishi FX2N Series: Legacy Compact PLC

Mitsubishi FX2N is the previous-generation MELSEC compact PLC – in production status “mature” (Mitsubishi continues to supply spare units and expansion modules, but FX2N is not specified for new machine designs). FX2N covered 24-256 total I/O with a large Malaysian installed base in machines built between 1995 and 2010.

FX2N-64MR – the 64 I/O relay output main unit: 32 DC 24V inputs, 32 relay outputs (250 VAC or 30 VDC rated). The most common FX2N model in Malaysian maintenance procurement, used as direct replacement for failed main units on legacy machinery.

FX2N-128MR – the maximum I/O FX2N compact main unit: 64 inputs + 64 relay outputs. Used in Malaysian packaging, automotive jig, and assembly machine applications where 128 I/O fits within a single main unit without expansion.

FX2N-48ES/UL – an I/O expansion unit (not standalone PLC): adds 48 I/O points to FX2N or FX3U main units. The /UL suffix indicates dual CE and UL certification – specified for Malaysian OEM machines exported to the USA and Canada, where UL 508A panel certification requires UL-rated automation components.

FX2N programming uses MELSEC Medoc or GX Works2 (ladder + SFC). Connection to laptop via dedicated RS-422 programming cable (SC-09 or FX-USB-AW USB adapter).

Mitsubishi FX3G Series: Current-Generation Mid-Range Compact PLC

Mitsubishi FX3G is the current-generation compact PLC successor to FX2N – 14 to 128 total I/O with built-in USB programming port (no dedicated cable required), 3-axis 100 kHz high-speed pulse output for stepper and servo driver step/direction control, and optional Ethernet communication module (FX3G-ENET-ADP) for SCADA connectivity.

FX3G-24M – 24 I/O main unit (14 inputs + 10 relay or transistor outputs). The FX3G entry model for Malaysian machine builders requiring a compact 24 I/O PLC with USB programming and high-speed pulse capability. Suffix variants: FX3G-24MR (relay output), FX3G-24MT (transistor sink output for stepper/servo driver).

FX3G-1DA – 1-channel 12-bit analog output expansion: 0-10 V or 4-20 mA selectable. Used for inverter speed reference (4-20 mA to FREQROL analog input) and process setpoint (0-10 V to pneumatic proportional valve or PID controller). Mounts on FX3G right-side expansion connector without additional power supply.

FX3G-1AD – 1-channel 12-bit analog input expansion: 0-10 V or 4-20 mA selectable. Used for process transmitter feedback (pressure, flow, temperature) to FX3G PLC PID loop. Resolution: 12-bit = 4,096 counts over the 4-20 mA range = 3.9 µA per count.

Mitsubishi FX3S Series: Entry Compact PLC

Mitsubishi FX3S covers 10-30 I/O – the entry-level FX3 compact PLC for simple Malaysian machine logic applications where FX3G’s 24-axis minimum is more I/O than required.

FX3S-10MR – 10 I/O (6 inputs + 4 relay outputs). Suitable for Malaysian simple machine safety interlock, sequential control, and indicator light sequencing applications where ladder logic complexity is low and I/O count is below 16.

FX3S-14MR-ES – 14 I/O (8 inputs + 6 relay outputs), CE-marked (ES suffix = European Standards compliance package). The -ES suffix models carry additional EMC documentation and CE declaration of conformity – required for Malaysian OEM machine builders supplying European markets.

Programming and Compatibility

All FX3G and FX3S models program with GX Works2 (Mitsubishi’s current IEC 61131-3 programming environment supporting ladder, SFC, structured text, and FBD). GX Works2 is not used for iQ-R or iQ-F platforms (those use GX Works3). The FX3G/FX3S USB mini-B port connects directly to a standard laptop USB port – no RS-422 cable or USB adapter required.

Mitsubishi FX-Series PLC FAQ

What is the difference between Mitsubishi FX2N and FX3G?

FX2N: legacy (RS-422 only, no USB), relay outputs, up to 256 I/O, stocked for spare/replacement. FX3G: current generation, built-in USB, 100 kHz HSP output, optional Ethernet, 14-128 I/O, for new builds.

What FX2N models does Flextech stock in Malaysia?

FX2N-48ES/UL (48 I/O expansion, CE+UL), FX2N-64MR (64 I/O relay), FX2N-128MR (128 I/O relay). Sourced for legacy installed base spare and replacement.

What are FX3G-1DA and FX3G-1AD expansion modules?

FX3G-1DA: 1-channel analog output (0-10V / 4-20mA) for inverter speed reference or process setpoint. FX3G-1AD: 1-channel analog input (0-10V / 4-20mA) for process transmitter feedback to PLC PID.

Is the FX2N-48ES/UL a standalone PLC?

No. It is an I/O expansion unit – adds 48 I/O points to an FX2N or FX3U main unit. /UL suffix = UL certification for USA/Canada export machine compliance.

What programming software does the FX3G use?

GX Works2 – ladder, SFC, structured text. USB mini-B direct laptop connection, no special cable required.
