Technical Questions

Q: What's the difference between fused and non-fused blocks?

A: Non-fused blocks like the 140CFK00400 provide termination without integrated fuses, suitable when external protection exists.

Q: Why support multiple signal types?

A> This flexibility allows use with various control devices without needing different terminal block types.

Q: How does it preserve 0.1% accuracy?

A: High-quality connections and proper terminal design minimize signal degradation from the module to field devices.

Q: What does 250V AC rating provide?

A: This allows safe separation between different voltage circuits within the same terminal block.

Q: When should I choose this non-fused version?

A: Select when your system has external protection or when fuse resistance might affect signal accuracy.
