Product Overview
When you need a compact yet powerful controller for high-speed automation tasks, the Mitsubishi FX3SA-20MT-CM delivers reliable transistor output performance. This 20-point PLC combines 12 inputs and 8 transistor outputs (drain type) in a space-saving design, making it ideal for precise positioning and rapid switching applications.
Technical Specifications Breakdown
The FX3SA-20MT-CM operates on a universal AC100-240V power supply, consuming only 20W. Its internal memory stores up to 16,000 steps in EEPROM, with a program capacity limited to 4,000 steps. For high-speed counting, it supports 1-phase 60 kHz on 2 points and 10 kHz on 4 points. The transistor output type enables positioning control on 2 axes at 100 kHz, ensuring accurate motion control.
Industry Applications
In packaging machinery, the FX3SA-20MT-CM handles high-speed counting and precise output switching. Its 2-axis positioning control at 100 kHz suits pick-and-place systems and conveyor indexing. For small assembly lines, the 20 I/O points provide enough flexibility for sensor inputs and actuator control without wasting space.
Installation & Setup Guidance
Mount the FX3SA-20MT-CM on a DIN rail or panel using the provided slots. Connect the AC100-240V power supply to the designated terminals, ensuring proper grounding. Wire transistor outputs as drain-type sinking outputs. Use the USB or RS-422 communication port for programming and monitoring via Mitsubishi software.
Maintenance & Reliability
With EEPROM memory, the FX3SA-20MT-CM retains programs without battery backup, reducing maintenance needs. Regularly inspect the power supply and output connections for tightness. The 20W power consumption keeps heat generation low, extending component life in enclosed panels.
Compatibility & Integration
The FX3SA-20MT-CM integrates with Mitsubishi FX series expansion modules and HMIs via the USB/RS-422 port. It communicates with supervisory systems using standard Mitsubishi protocols. The high-speed counter inputs connect directly to incremental encoders for speed and position feedback.
Selection Guide & Purchasing Advice
Before purchasing, verify your I/O count requirements: 12 inputs and 8 transistor outputs. Ensure your application benefits from the 100 kHz positioning and 60 kHz counting speeds. For replacement or new installations, the FX3SA-20MT-CM offers a cost-effective upgrade path. Contact SpareTechPLC for current availability and lead times.
