The FX3GA-40MT-CM belongs to Mitsubishi's FX3GA series. This model is a third-generation standard PLC. It combines basic control functions with flexible expansion capabilities. Many engineers choose it for small to medium automation tasks. The transistor sink outputs make it ideal for fast switching applications.
This PLC has a total of 40 input and output points. Specifically, it provides 24 digital input points and 16 digital output points. The output form is transistor output with sink type (drain). This allows direct connection to DC loads like solenoids, LEDs, and small relays.
Power supply is AC100-240V, covering standard industrial mains. Power consumption is only 37W, keeping energy use low. The unit weighs just 0.7 kg. Outline dimensions are 130mm wide, 90mm high, and 86mm deep. Therefore, it fits easily into crowded control panels.
For memory, the FX3GA-40MT-CM includes an EEPROM memory cartridge. It supports program transfer functions without a battery. This makes maintenance simple and worry-free. Built-in program memory holds 32000 steps. Basic instruction speed is 0.21 microseconds per instruction. Application instruction speed is 0.5 microseconds per instruction.
The FX3GA-40MT-CM offers generous internal resources. Auxiliary relays total 7680 points. Timers are available up to 320 points. Counters reach 235 points. Data registers provide 8000 points. Additionally, extended registers offer 24000 points. Extended file registers add another 24000 points. These capacities support complex control logic easily.
Internal consumption currents are clearly specified. DC5V internal consumption is 100mA. DC24V internal consumption is 125mA. The built-in power supply can also power some external devices. However, for larger loads, use an external power supply. This ensures stable operation of the FX3GA-40MT-CM.
The FX3GA-40MT-CM is highly scalable. You can connect up to 16 expansion modules. The maximum control points reach 128 points locally. Furthermore, when using CC-Link remote I/O, you can control up to 256 points. Total remote I/O points including CC-Link, AnyWireASLINK, and Bitty series can reach 512 points. This flexibility allows system growth over time.
Outline dimensions are exactly 130 x 90 x 86 mm (WxHxD). Weight is 0.7 kg. Operating ambient temperature ranges from 0°C to 55°C. Storage temperature ranges from -20°C to 70°C. Humidity should stay between 10% and 90% without condensation. Additionally, the unit meets various international standards. This makes it suitable for export and global applications.
First, disconnect all power before starting installation. Next, mount the FX3GA-40MT-CM on a DIN rail or using direct screws. Leave at least 50mm of free space above and below for ventilation. Then, connect AC power to the L and N terminals. The ground terminal must connect to a proper earth ground.
For input wiring, use 24V DC sinking or sourcing sensors. The built-in 24V DC supply can power these sensors up to 400mA. For output wiring, connect transistor sink outputs to DC loads. Each output can handle up to 0.5A. Protect inductive loads with freewheeling diodes.
Finally, after wiring, power up the unit. The PWR LED should light green. Connect programming software via the USB-A Mini port or RS422 port. GX Works2 or GX Developer works perfectly with this Mitsubishi FX3GA-40MT-CM.
This PLC excels in high-speed positioning and repetitive motion control. For instance, it works well in pick-and-place machines, small CNC systems, and labeling equipment. Additionally, it fits conveyor sorting systems, packaging machinery, and automatic test equipment. Because of the transistor outputs, you can achieve fast on-off cycles without relay wear.
The FX3GA-40MT-CM offers excellent value for small-scale control. It requires no battery, so maintenance costs are lower. The built-in EEPROM retains programs even during power loss. Moreover, its high-speed execution handles precise timing tasks easily. Compared to relay output models, transistor outputs last longer in high-frequency applications.
Overseas-oriented products meet various international standards. Therefore, you can use this PLC in different countries without compliance issues. The free combination of FX3G basic units (14/24/40/60 points) gives you a consistent platform across projects.

1. What is the difference between FX3GA-40MT-CM and FX3GA-60MR-CM?
The FX3GA-40MT-CM has transistor sink outputs with 40 total I/Os (24 in, 16 out). The FX3GA-60MR-CM has relay outputs with 60 I/Os. Transistor outputs switch faster and last longer. Relay outputs handle higher AC currents.
2. Can I expand the I/O beyond 40 points on this model?
Yes. The FX3GA-40MT-CM supports up to 16 expansion modules. Local control reaches 128 I/O points. With CC-Link remote I/O, you can reach 256 points total.
3. Does this PLC require a backup battery for program retention?
No. The FX3GA-40MT-CM uses built-in EEPROM memory. Your program stays saved even without power. No battery replacement is needed, making it maintenance-free.
4. What programming software works with the FX3GA-40MT-CM?
Mitsubishi GX Works2 and GX Developer both support this model. Connection is via the USB-A Mini port or RS422 port. The USB connection is plug-and-play on most computers.
5. Can I use the built-in 24V DC supply for all my sensors?
The built-in supply provides up to 400mA. For small sensors, this is sufficient. For larger loads, use an external 24V DC power supply. Exceeding 400mA may cause the FX3GA-40MT-CM to overheat or malfunction.
