Process Control & Safety Instrumented System Solution — YOKOGAWA ATA4S-00 S2 | CENTUM VP Series
Where This Product Is Used
The YOKOGAWA ATA4S-00 S2 is a field-proven analog I/O module deployed in mission-critical process automation environments worldwide. Engineers specify this module in:
- Oil & Gas Upstream/Midstream: FPSO vessels, wellhead control panels, and pipeline SCADA systems where SIL-rated I/O is mandatory.
- Petrochemical & Refining: Distillation column control, reactor temperature loops, and compressor surge control within CENTUM VP DCS architectures.
- Power Generation: Boiler management systems (BMS), turbine control, and grid-tie protection schemes requiring deterministic analog signal handling.
- Pulp & Paper / Chemical Plants: Continuous process lines where 4–20 mA loop integrity and redundancy are non-negotiable.
- Water & Wastewater Treatment: SCADA-integrated dosing control and pump station automation with IEC 61511 compliance requirements.

Why Engineers Specify This Model
- S2 Safety Revision: The “-S2” suffix denotes the second-generation safety-enhanced firmware, offering improved diagnostic coverage and reduced spurious trip rates versus the base ATA4S-00.
- Hot-Swap Capability: Modules can be replaced under power without shutting down the FCS node — critical for continuous process plants with zero-downtime requirements.
- Tight CENTUM VP Integration: Native Vnet/IP communication eliminates gateway latency; the module is recognized and configured directly within YOKOGAWA’s System View engineering tool.
- Proven SIL 2 Pedigree: Certified for use in Safety Instrumented Functions (SIFs) when deployed per YOKOGAWA’s SIL implementation guidelines, reducing third-party SIL assessment costs.
- Long Product Lifecycle: YOKOGAWA’s CENTUM VP platform carries a 10+ year support commitment, protecting capital investment in brownfield and greenfield projects alike.

Application-Specific FAQ
Q: Is the ATA4S-00 S2 backward-compatible with CENTUM CS 3000?
A: Compatibility depends on the CS 3000 revision and FCS hardware generation. The S2 module is primarily validated for CENTUM VP R5.x and later. Contact us with your FCS model number for a definitive compatibility check.
Q: Can this module be used in a Safety Instrumented System (SIS) without a separate safety PLC?
A: Yes — when deployed within a YOKOGAWA ProSafe-RS or CENTUM VP Integrated SIS architecture and configured per YOKOGAWA’s SIL implementation manual, the ATA4S-00 S2 can form part of a certified SIF loop up to SIL 2.
Q: What is the difference between ATA4S-00 and ATA4S-00 S2?
A: The S2 revision incorporates enhanced diagnostic firmware, improved HART pass-through support, and updated safety certification documentation. For new installations, S2 is the recommended revision.
Q: Do you offer repair or refurbishment services for this module?
A: Konmask offers exchange programs for select YOKOGAWA modules. Contact support@konmask.com with your defective unit’s serial number for an exchange quote.
