YOKOGAWA ATT4S-00 S2 – Analog Input/Output Module | CENTUM VP / CS 3000 DCS Platform
Engineering Background
The YOKOGAWA ATT4S-00 S2 is a field-proven analog I/O module engineered for YOKOGAWA’s CENTUM VP and CS 3000 Distributed Control System (DCS) platforms. Designed to interface directly with field instruments, it provides reliable signal conditioning and conversion between process-level analog signals and the DCS controller bus. The S2 hardware revision reflects YOKOGAWA’s continuous improvement cycle, incorporating enhanced EMI tolerance and improved terminal block reliability over earlier revisions.
Product Positioning
This module is the preferred choice for process engineers and automation integrators maintaining or expanding CENTUM VP / CS 3000 installations in refining, petrochemical, power generation, and pharmaceutical environments. As a genuine YOKOGAWA OEM component, the ATT4S-00 S2 ensures full backward compatibility with existing I/O bus architectures and YOKOGAWA engineering tools (CENTUM VP Engineering Environment).

- Reduced Commissioning Time: Auto-recognized by CENTUM VP engineering environment upon insertion.
System Architecture & Signal Flow
The ATT4S-00 S2 resides in the YOKOGAWA Field Control Station (FCS) I/O nest. Field wiring connects to the module’s terminal block, where analog signals are conditioned, digitized, and transmitted over the V-net/ER bus to the FCS processor. The S2 revision integrates an onboard EEPROM for module identification, enabling the CENTUM VP engineering environment to automatically detect module type, revision, and channel configuration without manual parameter entry.
Signal flow: Field Instrument → Terminal Block → ATT4S-00 S2 (A/D Conversion & Isolation) → V-net/ER Bus → FCS Processor → CENTUM VP HMI

Technical FAQ
Q: Is the ATT4S-00 S2 compatible with CENTUM VP R6.x?
A: Yes. The ATT4S-00 S2 is compatible with CENTUM VP R4.x through R6.x. Verify your FCS firmware version with YOKOGAWA support for edge cases.
Q: Can this module replace an ATT4S-00 S1?
A: In most installations, yes. The S2 is a hardware revision of the S1 with the same form factor and bus interface. Confirm with your CENTUM VP engineering environment before hot-swapping in safety-critical loops.
Q: Do you provide a test report?
A: A basic functional test record is available upon request. Contact support@konmask.com before purchase if a formal test report is required.
Q: What is the lead time for out-of-stock units?
A: Typical sourcing lead time is 2–4 weeks. Contact us to join the waitlist or request an alternative compatible module.
Q: Can I return the module if it is incompatible?
A: Yes, within 14 days of receipt, subject to our returns policy. The module must be returned in original condition and packaging.
