FAQ

Q: What is the main advantage of X20RT8401?

It provides both analog input and output in a single module with full digital I/O and encoder support.

Q: Can I use the analog input and output simultaneously?

Yes. Both analog channels operate independently within the 1 µs response framework.

Q: What encoder types are compatible?

24 V asymmetrical incremental encoders (A, B, R) with 333 kHz max frequency.
