Frequently Asked Questions

• Q: What is the resolution of the 1746-NI4 module?
  A: It provides high 16-bit resolution for very precise measurement of analog signals.
• Q: Can I use different input types on the same module?
  A: Yes. You can independently configure each of the four channels for either voltage or current input.
• Q: What is the module's update rate?
  A: Each channel updates its data very quickly, every 512 microseconds.
• Q: Is this module isolated?
  A: No, the 1746-NI4 has non-isolated differential inputs. Ensure proper system grounding.
• Q: Do you guarantee the product is genuine?
  A: Absolutely. We supply only authentic, brand-new Allen-Bradley products.
