MITSUBISHI MELSEC PLC FX3G-24M FX3S-30M FX3S-10MR FX3S-14MR-ES Programmable Controller Mitsubishi Electric FX3G FX3U FX3G-1DA FX3G-1AD

FX3G and FX3S are in current active production status from Mitsubishi Electric – unlike the legacy FX2N (mature/end-of-new-design), FX3G and FX3S carry full Mitsubishi Electric warranty, current firmware, and GX Works2 engineering tool support. Flextech quotes FX3G and FX3S models with same-day Klang Valley dispatch on standard configurations from Puchong, Selangor.

FX3G and FX3S Model Specifications

FX3G Compact PLC: 14-128 I/O Mid-Range

FX3G-24M (the “M” designates the main unit, suffix R = relay, T = transistor) provides 24 I/O in a compact DIN rail housing – the entry FX3G main unit for Malaysian machine automation requiring USB programming, RS-422 communication, and optional analog and Ethernet expansion.

High-speed pulse output on FX3G-24MT: The transistor output variant provides 3-axis simultaneous pulse output at 100 kHz – used for stepper motor driver and compatible servo drive step/direction positioning. A Malaysian packaging machine with 3 positioning axes (X, Y, and index table) can use a single FX3G-24MT as the motion controller, eliminating a dedicated motion module for applications where 100 kHz pulse rate is sufficient.

Ethernet option: FX3G-ENET-ADP adapter plugs into the FX3G left-side communication port, adding 10BASE-T/100BASE-TX Ethernet for SCADA Modbus TCP connectivity, GX Works2 remote programming, and MELSOFT Navigator HMI connection. This is the only way to add Ethernet to FX3G – the FX3S platform does not support Ethernet expansion.

FX3G Analog Expansion Modules

FX3G-1DA (1-channel analog output):

• Output range: 0-10 VDC or 4-20 mA (switch-selectable)
• Resolution: 12-bit (0-4,095 counts over the output range)
• Common use: inverter speed reference (4-20 mA → FREQROL analog input), proportional valve control (0-10 V → valve amplifier)
• Mounts directly on FX3G right-side port – no extension cable required

FX3G-1AD (1-channel analog input):

• Input range: 0-10 VDC or 4-20 mA (switch-selectable)
• Resolution: 12-bit (0-4,095 counts)
• Common use: pressure transmitter feedback (4-20 mA), thermocouple amplifier output (0-10 V), load cell signal conditioner
• FX3G PLC PID ladder instruction reads FX3G-1AD value → computes output → writes to FX3G-1DA → adjusts FREQROL speed → closed-loop process control

Malaysian machine builders use FX3G + FX3G-1AD + FX3G-1DA as a complete single-PLC closed-loop process controller for temperature, pressure, or flow control loops in packaging, food processing, and chemical applications.

FX3S Compact PLC: 10-30 I/O Entry Compact

FX3S-10MR – the smallest FX3 main unit: 10 I/O (6 inputs + 4 relay outputs) in a 60 mm DIN rail width. Suited for Malaysian simple machine safety logic, indicator sequencing, and 2-4 relay output control where FX3G’s 24 I/O minimum exceeds requirements.

FX3S-14MR-ES – 14 I/O (8 inputs + 6 relay outputs) with the -ES (European Safety) compliance documentation package: CE marking, EMC declaration of conformity (EN 61131-2), and RoHS documentation. -ES models are specified by Malaysian OEM machine builders supplying CE-required European or Australian markets where the complete CE compliance documentation set is required for machine technical file.

The FX3S does not support right-side analog expansion (FX3G-1DA/1AD are not compatible with FX3S). For FX3S analog requirements, use FX3S-CNV-ADP + external analog I/O unit on RS-485, or upgrade to FX3G platform.

Programming

FX3G and FX3S use GX Works2 – the current Mitsubishi IEC 61131-3 programming tool for FX-series (ladder, SFC, structured text). Built-in USB mini-B port on both FX3G and FX3S connects to laptop without dedicated RS-422 programming cable. GX Works2 provides simulation mode (offline program test without PLC hardware) – useful for Malaysian machine builders commissioning programs before machine delivery.

Mitsubishi FX3G FX3S FAQ

What is the I/O count and output type of the FX3G-24M?

24 total I/O: 14 inputs + 10 outputs. FX3G-24MR = relay outputs. FX3G-24MT = transistor sink, enables 3-axis 100 kHz pulse output for stepper/servo positioning.

What is the maximum I/O for FX3G?

128 total I/O with expansion units. Main unit available in 14-80 I/O configurations.

Does FX3S-14MR-ES support Modbus TCP?

No Ethernet on FX3S. Supports RS-485 Modbus RTU via FX3S-CNV-ADP + adapter. For Ethernet, upgrade to FX3G + FX3G-ENET-ADP.

What does -ES suffix mean on FX3S-14MR-ES?

European Safety compliance package – CE marking, EMC declaration (EN 61131-2), RoHS documentation. Required for Malaysian OEM machines supplied to European or CE-required markets.

What analog expansion is available for FX3G?

FX3G-1DA (1-ch analog output, 0-10V/4-20mA), FX3G-1AD (1-ch analog input, 0-10V/4-20mA). Both mount directly on FX3G right-side expansion port. Not compatible with FX3S.
