Mitsubishi FX3GA-40MT-CM PLC Unit: 24 DI, 16 DO Transistor Sink, 220VAC

Technical Specifications Breakdown

• Power Supply: AC100-240V, ensuring global compatibility.
• Input/Output Points: 40 total — 24 inputs and 16 outputs, with transistor (drain) output form for reliable switching.
• Power Consumption: 37W, keeping energy costs low.
• Weight: 0.7 kg, allowing easy installation in tight spaces.
• Dimensions: 130x90x86 mm, fitting compact control panels.
• Processing Speed: Basic instructions execute in 0.21 µs; application instructions in 0.5 µs, enabling fast logic handling.
• Memory: Built-in program memory of 32,000 steps, plus 8,000-step EPROM memory cartridge for program transfer.
• Internal Current Consumption: 100 mA at DC5V and 125 mA at DC24V.

These specs ensure the FX3GA-40MT-CM handles moderate I/O counts with minimal footprint and energy use.

Industry Applications

• Packaging Lines: The 24 inputs monitor sensor positions, while the 16 transistor outputs actuate solenoids and motors, all controlled by fast 0.21 µs instruction execution.
• Conveyor Sorting: With up to 256 control points via CC-Link remote I/O, this PLC coordinates multiple conveyor sections, reducing downtime and improving throughput.

Installation & Setup Guidance

Mount the FX3GA-40MT-CM on a DIN rail or panel using its 130x90x86 mm footprint. Connect AC100-240V to the power terminals, ensuring proper grounding. Wire digital inputs (24 points) to sensors and outputs (16 points) to loads, respecting the transistor sink configuration. Use the USB-A Mini port for programming via GX Works2 or similar software, and the RS422 port for serial communication with HMIs or other controllers. Expand I/O by adding up to 16 expansion modules, reaching a maximum of 256 I/O points.

Maintenance & Reliability

Routine inspection of terminal connections and power supply stability ensures long-term reliability. The maintenance-free EEPROM memory eliminates battery replacement. Keep the unit clean and within specified environmental limits (not provided, but standard industrial conditions apply). Periodic verification of I/O operation and communication links prevents unexpected failures.
