Selection Guide
Use the following criteria to determine if the F3YD08-6A is the right module for your application:
- Output count needed: 8 digital outputs → F3YD08-6A ✓
- Output polarity: Sink (NPN) → F3YD08-6A ✓ | Source (PNP) → F3YD08-6B
- Load voltage: 24 VDC → F3YD08-6A ✓
- High-density requirement: 16 points → consider F3YD16-6A
- Analog output needed: → consider F3YA04-6A or F3YA08-6A
- Mixed I/O: → consider F3XD08-6A (input) + F3YD08-6A (output) combination

Replacement & Compatibility FAQ
Q: Can F3YD08-6B replace F3YD08-6A directly?
A: Only if your field devices support source (PNP) output. The electrical polarity differs — verify your wiring before substitution.
Q: Is F3YD08-6A still in production?
A: YOKOGAWA periodically updates its STARDOM product line. Contact Konmask for current availability and lifecycle status.
Q: Can I use a third-party I/O module in the FCN backplane?
A: Some third-party modules claim compatibility, but YOKOGAWA does not officially support them. Using OEM modules ensures full firmware and warranty coverage.
Q: Do you provide a warranty on F3YD08-6A units?
A: Yes. Konmask.com offers a 90-day functional warranty on all verified units. Extended warranty available upon request.
Q: Can you source discontinued or obsolete YOKOGAWA modules?
A: Yes. We specialize in legacy and hard-to-find industrial automation components. Submit your part number for a sourcing inquiry.
