Selection Guide
Use the criteria below to confirm the F3XD08-6N is the right module for your application, or to identify a suitable alternative:
- I/O Point Count: Need exactly 8 DI points → F3XD08-6N ✓ | Need 16 points → F3XD16-6N | Need 32 points → F3XD32-6N
- Signal Voltage: 24 VDC field signals → F3XD08-6N ✓ | 100–120 VAC signals → consider F3XD08-1N
- Wiring Type: Sink or source (NPN/PNP) → F3XD08-6N ✓ (dual-polarity)
- Response Speed: Standard control (≥1 ms) → F3XD08-6N ✓ | High-speed pulse/encoder → F3XD08-6H
- Connector Style: Confirm terminal block type matches existing wiring harness
- Slot Availability: Verify available slots on your FA-M3 base unit before ordering

Replacement & Compatibility FAQ
Q: Can I replace F3XD08-6N with F3XD16-6N without changing the program?
A: The F3XD16-6N occupies the same slot but maps 16 points. You must update the I/O assignment in WideField3 and verify that unused points do not trigger unintended logic.
Q: Is F3XD08-6N compatible with the older FA-M3 (non-R) base units?
A: Yes, the F3XD08-6N is compatible with both FA-M3 and FA-M3R base units. Confirm the base unit firmware version supports the module revision you receive.
Q: Can I mix NPN and PNP field devices on the same F3XD08-6N module?
A: The F3XD08-6N supports both sink (NPN) and source (PNP) wiring per point, but all points share a common terminal. Mixing polarity types on the same module is not recommended without consulting the wiring diagram.
Q: What is the lead time for F3XD08-6N?
A: In-stock units ship within 1–3 business days. For out-of-stock situations, typical lead time is 2–6 weeks depending on sourcing channel. Contact us for real-time availability.
Q: Do you provide a certificate of authenticity?
A: Yes. A certificate of conformance and sourcing documentation are available upon request for all orders.
