FAQ

• Q: Is this module sink or source type? A: F3XD16-3F supports both sink and source input configurations for flexible wiring.
• Q: What is the isolation voltage? A: Photocoupler isolation provides 2500V DC common mode voltage protection between inputs and internal circuits.
• Q: Can it handle high-speed counting? A: While fast, dedicated high-speed counter modules (F3CU04 series) are recommended for counting applications above standard scan rates.
• Q: What wire gauge is recommended? A: Use 0.75-1.25 mm² (18-16 AWG) wire with the detachable terminal block.

Installation Guide

1. Power off the FA-M3 system.
2. Insert F3XD16-3F into any available I/O slot.
3. Connect 24V DC sensors to the terminal block observing proper polarity.
4. Configure sink or source wiring as required by your sensor type.
5. Restore power and verify input LEDs illuminate when sensors are activated.
6. Test all 16 channels systematically for proper on/off detection.

Selection Tips

• Choose F3XD16-3F for standard 24V DC digital inputs with photocoupler isolation.
• For 32-point density, consider F3XD32-3F to reduce module count and rack space.
• For 64-point high-density applications, F3XD64-3N provides maximum I/O density.
• Verify sensor output type (PNP/NPN) matches your sink/source wiring configuration.
