Key performance note: The module delivers fast response with selectable sampling down to 62.5 μs. It maintains 100% simultaneous ON ratio. Isolation protects the backplane from field transients. The 32-point density saves panel space. The 8-point common simplifies wiring and fault isolation.
Installation Guide
- Mount the module in a Yokogawa rack or compatible enclosure.
- Confirm 12 V DC field power before wiring.
- Use the 40-pin connector for input signals. Follow pin assignments in the manual.
- Keep common groups isolated. Each group handles up to 8 points.
- Respect the 10.2 – 13.2 V DC operating range. Do not exceed 13.2 V DC.
- Allow air flow. Keep ambient temperature within 0 to 55 °C.
- Avoid corrosive gases, flammable gases, and heavy dust.
Commissioning and Maintenance Convenience
- Set input response time per channel: Always, 62.5 μs, 250 μs, 1 ms, or 16 ms.
- Enable per-point interrupts for event-driven logic.
- Verify ON state at 8.0 V DC min. / 2.6 mA min.
- Verify OFF state at 3.4 V DC max. / 1.0 mA max.
- Check current draw: 75 mA at 5 V DC.
- Inspect the 40-pin connector for secure seating during routine checks.
- Log module temperature. Keep within the stated operating range.
Compatibility and Diagnostics
The F3XD32-4F fits Yokogawa F3 series racks and systems that accept the 40-pin input module format. It supports sink or source field wiring. Use it to replace failed modules in existing installations. The photocoupler isolation and per-point interrupt capability help engineers diagnose field wiring faults.
