Replacement & Compatibility FAQ
Q: Is FX1N-40MR-JY331BA8302H the same as FX1N-40MR-001?
A: The JY331BA8302H suffix is Mitsubishi’s internal production/revision code. Functionally, it is equivalent to the standard FX1N-40MR-001 for most applications. Confirm with your system documentation if a specific revision is required.
Q: Can I replace FX1N-40MR with FX3G-40MR?
A: Yes, with minor program migration. FX3G is backward-compatible with most FX1N instructions. Wiring is largely identical; verify special module compatibility.
Q: Does Konmask ship internationally?
A: Yes. We ship worldwide via DHL, FedEx, and UPS with full export documentation.
Q: What if I need a different I/O count?
