Product Details

ATA4D-00 S2 Product Description

The Yokogawa ATA4D-00 S2 is a precision analog input module engineered for seamless integration within the CENTUM VP and CS 3000 Distributed Control System (DCS) platforms. Designed to serve as a critical signal acquisition node in multi-layer industrial control architectures, this module delivers stable, high-resolution analog signal processing across demanding process environments including petrochemical refining, power generation, water treatment, and continuous manufacturing. Its role within the control hierarchy extends far beyond simple signal conversion — the ATA4D-00 S2 functions as a foundational I/O layer component that directly supports control loop integrity, system redundancy, and long-term diagnostic efficiency.

In a fully realized CENTUM VP architecture, the ATA4D-00 S2 occupies the I/O layer, receiving 4–20 mA or voltage signals from field transmitters and converting them into digital process values consumed by the Field Control Station (FCS). This signal flow underpins every upstream control decision, from PID loop execution to alarm management and historian logging. The module's compatibility with the CENTUM VP node bus ensures deterministic scan cycle performance, a prerequisite for tight process control in high-throughput applications.

System architects deploying the ATA4D-00 S2 benefit from its native compatibility with the Yokogawa RIO (Remote I/O) bus and the standard I/O nest architecture. When paired with the ANB10D or ANB11D I/O nest backplane, the module slots directly into the node structure without requiring additional signal conditioning hardware. This plug-and-play integration reduces commissioning time and eliminates potential signal chain discontinuities introduced by third-party interface components. For projects requiring I/O expansion, the ATA4D-00 S2 can be deployed alongside additional analog output modules such as the ATA4D-10 or digital I/O modules including the ADV151-P00 and ADV551-P00, enabling a fully modular, scalable I/O subsystem within a single control cabinet.

Redundancy is a core design consideration in process-critical DCS deployments. The ATA4D-00 S2 supports dual-redundant I/O configurations when paired with the Yokogawa redundant I/O module framework, ensuring that a single module failure does not interrupt process variable acquisition. This capability is particularly valuable in safety-instrumented environments where continuous signal availability is mandated by IEC 61511 or equivalent functional safety standards. The module's hardware design incorporates channel-level isolation, protecting the control system backplane from field-side transients and ground loops that are common in electrically noisy industrial environments.

From a communications and diagnostics perspective, the ATA4D-00 S2 integrates transparently with the CENTUM VP engineering environment, including the System View and Hardware Configurator tools. Maintenance engineers can perform online diagnostics, channel-level status monitoring, and module health checks without interrupting live process control. This non-intrusive diagnostic capability significantly reduces mean time to repair (MTTR) and supports predictive maintenance strategies that extend overall system uptime. When combined with the Yokogawa FAST/TOOLS SCADA platform or the Exaquantum process data historian, the analog input data acquired by the ATA4D-00 S2 feeds directly into plant-wide performance analytics and regulatory compliance reporting.

Power supply integrity is equally critical to reliable analog input performance. The ATA4D-00 S2 draws regulated DC power from the node power supply unit, typically the Yokogawa PW481 or PW482 series, which provides stable, filtered power to all I/O modules within the nest. Voltage fluctuations or power supply degradation can introduce measurement drift or module faults; therefore, deploying a redundant power supply configuration is strongly recommended for continuous process applications. The module's low power consumption profile also makes it suitable for high-density I/O configurations where thermal management within the control cabinet is a design constraint.

For engineering teams managing large-scale DCS migrations or brownfield expansions, the ATA4D-00 S2 offers a direct replacement path for legacy CS 3000 analog input modules, preserving existing wiring infrastructure and I/O nest assignments. This backward compatibility reduces migration risk and project cost, allowing phased system upgrades without full I/O rewiring. The module's firmware is compatible with current CENTUM VP R6 software releases, ensuring long-term vendor support and access to security patches and feature updates.

Every ATA4D-00 S2 unit supplied by NANKMOS undergoes pre-shipment functional testing, including channel accuracy verification, isolation resistance measurement, and communication bus handshake confirmation. Units are shipped with full traceability documentation and are covered by a 12-Month Warranty against manufacturing defects and functional failures. Our inventory is maintained in climate-controlled storage to preserve module integrity, and same-week dispatch is available for in-stock units to support urgent project timelines.

The ATA4D-00 S2 achieves its full performance potential when deployed as part of a cohesive CENTUM VP automation platform. At the control layer, the Yokogawa AFV10D or AFV30D Field Control Station (FCS) executes the PID and advanced control algorithms that consume the analog input data provided by the ATA4D-00 S2. The FCS communicates with the I/O modules via the high-speed Vnet/IP control network, ensuring sub-millisecond scan cycle consistency across all process loops.

At the I/O layer, the ATA4D-00 S2 operates alongside complementary modules including the ATA4D-10 analog output module for closed-loop control, the ADV151-P00 digital input module for discrete status acquisition, and the ADV551-P00 digital output module for actuator command signals. These modules share the ANB10D backplane, forming a compact, high-density I/O subsystem that minimizes cabinet footprint while maximizing channel count per rack unit.

For communication-intensive architectures requiring fieldbus integration, the Yokogawa ALF111 FOUNDATION Fieldbus H1 interface module or the ALE111 PROFIBUS DP interface module can be deployed within the same I/O nest, enabling hybrid architectures that combine traditional 4–20 mA wiring with digital fieldbus segments. This flexibility supports phased migration strategies where legacy analog instruments coexist with modern smart field devices.

At the HMI layer, the Yokogawa CENTUM VP Operator Station (HIS) provides real-time visualization of all analog input values acquired by the ATA4D-00 S2, with configurable trend displays, alarm annunciation, and faceplates for individual control loops. The operator station communicates with the FCS via the Vnet/IP network, ensuring that process variable updates are reflected on the HMI within the system's defined scan cycle. For remote monitoring applications, the FAST/TOOLS SCADA platform extends this visibility to plant-wide dashboards and mobile operator interfaces.

Power architecture integrity is maintained by the PW481 redundant power supply module, which provides dual-feed DC power to the I/O nest. In conjunction with the ATA4D-00 S2's internal channel isolation, this power redundancy ensures that neither a field-side fault nor a power supply failure can propagate to the control system backplane, preserving overall system availability in continuous process environments.

Petrochemical & Refining: In crude distillation and hydrocracking units, the ATA4D-00 S2 acquires temperature, pressure, and flow signals from field transmitters installed on process vessels and pipelines. The module's 16-bit resolution supports the tight measurement accuracy required for advanced process control (APC) applications, where small deviations in feed composition or reactor temperature can significantly impact product yield and energy consumption.

Power Generation: In combined-cycle gas turbine (CCGT) and coal-fired power plants, the ATA4D-00 S2 monitors analog signals from vibration sensors, thermocouple transmitters, and pressure transducers installed on turbine and boiler systems. Its compatibility with the CENTUM VP FCS enables integration with turbine control and protection systems, supporting coordinated startup, load following, and emergency shutdown sequences.

Water & Wastewater Treatment: Municipal and industrial water treatment facilities deploy the ATA4D-00 S2 to monitor flow rates, pH levels, dissolved oxygen concentrations, and chemical dosing pump outputs. The module's channel isolation prevents ground loop interference from electrochemical sensors, which are common sources of signal noise in water treatment environments.

Mining & Metallurgy: In ore processing and smelting operations, the ATA4D-00 S2 acquires analog signals from load cells, belt weighers, and temperature sensors installed on crushers, conveyors, and furnaces. Its robust operating temperature range and vibration tolerance make it suitable for the harsh electrical environments typical of heavy industrial facilities.

Packaging & Continuous Manufacturing: High-speed packaging lines and continuous web processing systems use the ATA4D-00 S2 to monitor tension, speed, and position signals from servo drives and tension transducers. The module's deterministic scan cycle performance supports the tight synchronization requirements of multi-axis motion control applications integrated within the CENTUM VP architecture.

Q1: Is the ATA4D-00 S2 compatible with both CENTUM VP and CS 3000 systems? Yes. The ATA4D-00 S2 is designed for use in both CENTUM VP and CS 3000 DCS platforms. It is physically and electrically compatible with the standard I/O nest backplanes (ANB10D / ANB11D) used in both systems. When migrating from CS 3000 to CENTUM VP, existing ATA4D-00 S2 modules can be retained in place, preserving field wiring and reducing migration cost. Software configuration is managed through the respective engineering environments — CENTUM VP Hardware Configurator for VP systems and CS 3000 System Builder for legacy installations.

Q2: Can the ATA4D-00 S2 be used in a redundant I/O configuration, and what additional components are required? Yes. The ATA4D-00 S2 supports redundant I/O deployment within the CENTUM VP architecture. A redundant configuration requires a paired ATA4D-00 S2 module installed in the redundant I/O nest slot, along with the appropriate redundant I/O nest backplane and the Yokogawa redundant I/O coupler module. The FCS automatically manages switchover between primary and redundant modules in the event of a module fault, ensuring uninterrupted analog input acquisition.
