Applications & Suitable Equipment

• Common industries
  • Conveyor systems – motor starters and sensors
  • Packaging machines – filling, sealing, labeling
  • HVAC control – fans, pumps, valves
  • Small assembly lines – pick-and-place stations
  • Water treatment – pump control and monitoring
• Compatible devices
  • AC motors (via contactors)
  • Solenoid valves (AC or DC)
  • Indicator lights and alarms
  • NPN or PNP sensors (24V DC inputs)
  • HMI panels via RS-422

Frequently Asked Questions (FAQ)

• Q1: Can the FX2N-48MR-001 control AC motors directly?
  A: No. Relay outputs can switch contactor coils. Use external contactors or motor starters for motor power.
• Q2: How do I expand I/O beyond 48 points?
  A: Add FX2N expansion units on the right side. Maximum total I/O is 256 points.
• Q3: Does the unit keep the program when power is off?
  A: Yes. Built-in battery backs up RAM. Program and data remain safe during power loss.
• Q4: What software do I need for programming?
  A: GX Works2 or GX Developer. Connect via RS-422 programming cable (SC-09 or USB adapter).
• Q5: How many analog modules can I connect?
  A: Up to 8 special function modules (analog, temperature, positioning) depending on power budget.
