F3XD16-3F Yokogawa DC Input Module – 16-Point Fast Response Input for F3 Series
The F3XD16-3F is a Yokogawa DC input module for the F3 series. It offers 16 input points with photocoupler isolation. Each point accepts sink or source wiring. The module suits high-density panels that need fast, reliable 24 V DC sensing. Input sampling time is selectable in 5 steps, down to always-on (0 μs). Interrupts are configurable per point. Two 8-point commons simplify field wiring.

Response and noise notes: Fast sampling steps reduce input lag for pulse and interlock signals. Photocoupler isolation blocks field noise from the bus. The module holds a stable ON/OFF threshold across the full 20.4 to 26.4 V DC range.
Installation Guide
- Mount the module in an F3 series rack or base unit.
- Wire field signals to the 18-point M3.5 screw terminal block.
- Use the 8-point commons to group inputs by field circuit.
- Keep 24 V DC wiring away from high-current cables to cut noise.
- Set each input point as sink or source to match the sensor.
- Set the sampling time in software before you start the process.
Commissioning and Maintenance
Check the ON/OFF voltage with a meter during startup. Confirm each point reads the correct state in the engineering tool. Set interrupts only on points that need fast event capture. Keep the terminal screws tight to avoid intermittent inputs. Clean the module with dry air only. No calibration is needed in normal service.
Compatibility
The F3XD16-3F fits Yokogawa F3 series I/O slots. It works with standard 24 V DC sensors, switches and relay contacts. Sink and source field devices share the same module. Confirm the base unit slot count before you order. Contact our team for cross-reference help on legacy F3 systems.
Diagnostics
Per-point status shows in the engineering tool. The fast sampling steps help you trace short pulses. Interrupt flags help you find the first event in a sequence. Stable ON/OFF thresholds make field faults easy to spot. The photocoupler design limits false triggers from ground noise.
Typical Applications
- Discrete sensor and limit switch input in process plants.
- Interlock and status monitoring in machine control.
- Fast event capture on packaging and assembly lines.
- Legacy F3 system expansion and spare replacement.
- Panel builds that need 16 inputs in one slot.
