FAQs

1. How many voltage input channels does the module provide?

   It provides two independent voltage input channels.

2. What voltage ranges are supported?

   The module supports both 0–10 V and ±10 V ranges.

3. Does it provide channel-to-channel isolation?

   No, the two channels share a common reference.

4. Is filtering configurable?

   Yes, software-configurable digital filtering is supported through the controller.

5. What is the resolution of the input conversion?

   The module uses a 15-bit plus sign A/D converter.

6. Can it operate in high-temperature panels?

   Yes, up to +55 °C without derating.

7. How is calibration handled?

   Factory-calibrated; field calibration is typically not required.

8. How does it receive power?

   Through the POINT I/O backplane from its base module.

9. Is the wiring shielded or unshielded?

   Both can be used; shielded wiring is recommended for noise-sensitive applications.

10. What controller families are compatible?

    CompactLogix, ControlLogix, and any system supporting POINT I/O adapters.
