Why Engineers Specify This Model
- High-Density Channel Count: 8 isolated AI channels per slot maximise I/O density in space-constrained marshalling cabinets.
- 16-Bit Resolution: Delivers fine-grained process variable resolution essential for tight regulatory control loops (e.g., cascade temperature control).
- HART Pass-Through: Enables device diagnostics and remote configuration of HART-enabled field instruments without additional multiplexers.
- Hot-Swap Capability: Supports online module replacement in redundant CENTUM VP configurations, eliminating planned shutdowns for maintenance.
- Proven Platform Longevity: CENTUM VP has an established multi-decade lifecycle with YOKOGAWA’s committed long-term parts support policy.
- Deterministic Scan Cycle: Synchronised with the CENTUM VP field control station (FCS) scan for predictable, jitter-free data acquisition.

Application-Specific FAQ
Q: Is the ASI133-S00 compatible with CENTUM CS 3000 as well as CENTUM VP?
A: The ASI133-S00 is primarily designed for CENTUM VP I/O nests. Compatibility with CS 3000 depends on the specific node revision. Contact our team with your CS 3000 FCS model number for confirmation.
Q: Can this module be used in a SIL-rated safety loop?
A: For SIL-rated applications, YOKOGAWA’s ProSafe-RS platform with dedicated safety I/O modules is the correct solution. The ASI133-S00 is a standard (non-safety) AI module and should not be used as the primary safety element in a SIL loop without a formal functional safety assessment.
Q: Does the module support HART communication?
A: Yes. The ASI133-S00 supports HART pass-through, allowing HART commands to be issued to field devices via the CENTUM VP HART DTM or an external HART multiplexer.
Q: What is the scan cycle time for analog inputs on this module?
A: Scan cycle is determined by the CENTUM VP FCS configuration, typically 100 ms to 1000 ms selectable. The ASI133-S00 updates its channel data synchronously with the FCS scan.
Q: Can I replace a failed ASI133-S00 online without shutting down the process?
A: In a redundant CENTUM VP configuration with a standby FCS or redundant I/O, hot-swap replacement is supported. In a simplex configuration, the associated control loops will go to their configured fail-safe state during module replacement.
Q: What lead time should I expect?
A: In-stock units ship within 1–2 business days. For sourced units, typical lead time is 3–10 business days depending on global inventory availability. Expedited options are available — contact us for urgent requirements.
