Performance & Core Features

• Compact yet powerful: The FX3SA-20MR-CM fits tight panels while providing 20 I/O points for small equipment control.
• Relay output durability: Handles inductive loads like motors, solenoids, and contactors with ease. Each relay supports up to 2A per point.
• Flexible expansion options: Connect FX2NC expansion modules directly without extra cables. You can expand I/O up to 60 points total.
• Built-in high-speed counter: Use simple programming for positioning or frequency measurement. The filter adjusts down to 1ms for precise input capture.
• Analog & communication ready: Support analog special adapters and MODBUS communication out of the box. Add Ethernet modules for network integration.
• Maintenance-free design: No battery backup required. EPROM memory retains programs reliably over years of operation.
• RUN/STOP switch: Operate the panel-mounted switch easily without software.
• Remote maintenance: Use modem communications for remote programming, monitoring, and program uploads or downloads.
• Continuous scanning function: Define operation cycles with continuous scan time for time-critical applications.
• Online program editor: Change programs without losing work hours or stopping production.
• Component annotation: Record notes in program registers for better documentation.

Frequently Asked Questions (FAQ)

• Q: Can I use analog modules with this PLC?
  A: Yes. The FX3SA-20MR-CM supports analog special adapters for applications needing temperature or pressure monitoring.
• Q: What software do I need to program it?
  A: Use Mitsubishi GX Works2 or GX Developer. Both support the FX3SA series with full instruction sets.
• Q: Does this model support MODBUS communication?
  A: Absolutely. The FX3SA-20MR-CM includes built-in MODBUS RTU capability. Add an Ethernet adapter for network connectivity.
• Q: How many I/O points can I expand to?
  A: You can reach up to 60 total I/O points when combining with FX2N expansion units and special adapters.
• Q: Is the unit battery-free?
