What Is the Mitsubishi FX3GA-60MT-CM?
Struggling to find a compact PLC that balances performance with cost for small-scale control? The Mitsubishi FX3GA-60MT-CM delivers a reliable solution. This third-generation standard model from the FX3 series combines high-speed operation with large memory capacity. It features 60 input/output points, including 36 inputs and 24 transistor outputs (drain type). Powered by AC100-240V, it consumes only 40W. The unit weighs 0.85 kg and measures 175x90x86 mm. An EEPROM memory cartridge with program transfer function is built in, eliminating the need for a battery and simplifying maintenance.

Industry Applications
Small-Scale Machine Control
In packaging or assembly machines, the FX3GA-60MT-CM handles up to 128 control points (256 with CC-Link remote I/O). Its transistor outputs can generate two 100 kHz pulse trains to drive servo or stepper motors directly. This makes it ideal for simple manipulators or pick-and-place systems.
Building Automation
For HVAC or lighting control, the compact size (175x90x86 mm) fits easily into small panels. The EEPROM memory retains programs without battery backup, reducing maintenance visits.
Cost-Sensitive Projects
As a high-value controller, the FX3GA-60MT-CM offers a low entry cost for applications that do not require extensive expansion. Its flexible scalability allows adding BD boards for RS232, RS485, or RS422 communication when needed.
Installation & Setup Guidance
Mount the FX3GA-60MT-CM on a DIN rail or directly onto a panel using the provided slots. Ensure adequate ventilation around the unit to maintain operating temperature. Connect the AC power supply (100-240V) to the designated terminals. Wire input devices (sensors, switches) to the 36 input points and output loads (solenoids, motors) to the 24 transistor outputs. Use the EEPROM memory cartridge to transfer programs easily. No battery is required for memory retention.
Maintenance & Reliability
The FX3GA-60MT-CM requires minimal routine care. Periodically inspect the unit for dust accumulation on the vents and clean with a dry cloth if needed. Verify that all terminal connections remain tight. The absence of a battery eliminates periodic replacement tasks. For long-term reliability, operate within the specified power range (AC100-240V) and avoid exposing the unit to excessive vibration or moisture.
Compatibility & Integration
This PLC integrates seamlessly with other FX3 series components. It supports expansion via BD boards for serial communication (RS232, RS485, RS422). For larger systems, use CC-Link remote I/O to control up to 256 points. The transistor outputs can directly drive servo or stepper motor drives without additional interface modules.
Selection Guide & Purchasing Advice
Before ordering the FX3GA-60MT-CM, confirm your I/O requirements: 36 inputs and 24 outputs. If you need more I/O, consider the FX3G series with 14/24/40/60 point basic units or add BD boards for limited expansion. Verify that the AC power supply in your facility matches the 100-240V input. For applications requiring analog I/O or Ethernet, evaluate the FX3GE series. SpareTechPLC stocks this model and can advise on availability and lifecycle status.
