System Compatibility
The AD908AC is designed for use within the FOXBORO I/A Series DCS platform. Confirm compatibility with the following before ordering:
- I/A Series rack / enclosure model and available slot type
- Nodebus or Fieldbus topology in use
- DCS software version (I/A Series System Software release)
- Power supply capacity of the target rack
- Signal type and range required (AI, AO, DI, DO — verify per module datasheet)
Selection Guide
Use the following decision framework to confirm the AD908AC is the right module for your application:
- Identify your I/O requirement: Analog input, analog output, digital input, or digital output?
- Confirm channel count: Match the number of field signal channels required.
- Verify signal range: 4–20 mA, 0–10 V, thermocouple, RTD, or discrete?
- Check rack slot availability: Confirm physical slot type and backplane compatibility.
- Review firmware requirements: Ensure your DCS software version supports the AD908AC.
- Evaluate redundancy needs: Determine if a redundant module pair is required for your SIL/availability target.
- Compare with alternatives: If the AD908AC is obsolete or unavailable, review the equivalent models table above.
