Compatible Replacement & Equivalent Models
When the AAI135-S00 S2 is unavailable or end-of-life, the following models may serve as functional equivalents or replacements depending on system configuration:
- AAI135-S00 S1 — Earlier hardware revision; functionally equivalent in most CENTUM VP applications. Verify firmware compatibility before substitution.
- AAI141-S00 — 8-channel AI module; suitable when channel density can be reduced. Lower cost per unit.
- AAI143-S00 — 16-channel AI with HART communication support; recommended upgrade path for HART-enabled field devices.
- AAI835-S00 — High-accuracy AI module for precision measurement applications requiring tighter tolerances.
- Third-party compatible modules — Contact Konmask.com for cross-reference analysis. We evaluate signal type, channel count, bus protocol, and nest compatibility before recommending any alternative.
⚠ Important: Always verify hardware revision, firmware version, and nest slot compatibility before installing any replacement module in a live DCS environment.

Selection Guide
Use the following criteria to confirm the AAI135-S00 S2 is the correct module for your application:
- ✅ Signal type: Your field devices output 4–20 mA analog current signals
- ✅ Channel count: You require 16 input channels per module slot
- ✅ Platform: Your DCS is CENTUM VP or CS 3000
- ✅ HART not required: Field devices do not require HART digital communication (if HART needed → consider AAI143-S00)
- ✅ Standard accuracy: Application does not require high-precision measurement (if high accuracy needed → consider AAI835-S00)
- ✅ Hardware revision: Confirm S2 revision is specified in your system BOM or spare parts list

Replacement & Compatibility FAQ
Q: Can I replace AAI135-S00 S2 with AAI135-S00 S1?
A: In most cases yes — S1 and S2 are hardware revisions of the same module family. However, verify that your CENTUM VP firmware version supports the S1 revision. Contact us for a compatibility check.
Q: Does the AAI135-S00 S2 support HART communication?
A: No. The AAI135-S00 S2 is a standard 4–20 mA analog input module without HART support. For HART-enabled applications, consider the AAI143-S00.
Q: Can this module be used in a CS 3000 system?
A: Yes, with the appropriate I/O nest. Confirm nest model compatibility with your CS 3000 system drawing before ordering.
