Yokogawa ATI3S-00 S2 Terminal Block

Product Details

ATI3S-00 S2 Product Description

The Yokogawa ATI3S-00 S2 is a system-ready terminal block engineered for seamless integration within the CENTUM VP and CS 3000 Distributed Control System (DCS) architecture. Designed to serve as a critical I/O interface node, this terminal block ensures reliable signal termination, consistent electrical continuity, and structured wiring discipline across multi-loop process control environments. Whether deployed in greenfield automation projects or brownfield upgrades, the ATI3S-00 S2 delivers the mechanical precision and electrical integrity demanded by continuous process industries.

In modern industrial control architecture, the terminal block layer is far more than a passive wiring component — it is the structural backbone that connects field instrumentation to the I/O subsystem, enabling accurate signal transmission from sensors, transmitters, and actuators into the DCS controller. The ATI3S-00 S2 is purpose-built for this role within Yokogawa's modular control platform, supporting high-density I/O marshalling, loop integrity verification, and systematic cable management in control cabinets operating under demanding environmental conditions.

Every unit supplied by NANKMOS undergoes pre-shipment functional testing and is backed by a 12-Month Warranty, ensuring that your control architecture maintains operational continuity from commissioning through long-term production cycles.

The ATI3S-00 S2 terminal block operates as a foundational element within a layered CENTUM VP control architecture. Its value is best understood in the context of the complete automation platform it supports. At the controller layer, the Yokogawa ACF11 Field Control Station (FCS) and ACF12 FCS serve as the primary processing nodes, executing control logic and managing I/O communication across the system bus. The ATI3S-00 S2 provides the physical termination point that bridges field instrument cabling to the I/O modules housed within the FCS node racks.

Within the I/O subsystem, the ATI3S-00 S2 works in conjunction with Yokogawa's AAI141 Analog Input Module and AAI841 Analog I/O Module, which handle 4–20 mA signal conditioning and HART pass-through communication. For digital control loops, the ADV151 Digital Input Module and ADV551 Digital Output Module rely on properly terminated field wiring — a function the ATI3S-00 S2 fulfills with consistent contact resistance and mechanical stability across thousands of connection cycles.

At the communication layer, the CENTUM VP architecture integrates Vnet/IP as its primary control network, with the ACP71 Communication Module managing inter-node data exchange. The ATI3S-00 S2 ensures that field-level signal integrity is maintained upstream of this communication layer, preventing noise-induced errors from propagating into the control network. For installations requiring FOUNDATION Fieldbus or PROFIBUS PA integration, the ALF111 Fieldbus Communication Module interfaces with field devices through the same marshalling cabinet where the ATI3S-00 S2 is installed.

Power distribution within the control cabinet is managed by Yokogawa's APW122 Power Supply Module, which provides regulated 24 VDC to I/O modules and field instruments. The ATI3S-00 S2 terminal block is positioned within this power distribution architecture to ensure that field loop power and signal return paths are cleanly separated, reducing common-mode interference in sensitive analog measurement loops.

For HMI and operator interface, the CENTUM VP platform connects to Yokogawa FAST/TOOLS SCADA and the integrated HIS (Human Interface Station), which displays real-time process data sourced from the I/O modules connected through the ATI3S-00 S2 termination layer. Accurate signal termination at the ATI3S-00 S2 level directly impacts the quality of process variable data displayed at the operator workstation.

In redundant architecture deployments — common in oil & gas, power generation, and chemical processing — the ATI3S-00 S2 supports dual-redundant I/O configurations where field signals are simultaneously terminated to primary and secondary I/O modules. This redundancy design, combined with the ProSafe-RS Safety Instrumented System (SIS) for safety-critical loops, ensures that a single point of failure at the termination layer does not compromise process safety or availability.

Petroleum Refining & Petrochemical Processing: In refinery DCS architectures, the ATI3S-00 S2 is deployed in marshalling cabinets that aggregate field signals from temperature transmitters, pressure sensors, and flow meters across distillation columns, heat exchangers, and reactor units. The terminal block's reliable screw-type termination ensures that 4–20 mA analog signals from Yokogawa EJA-series pressure transmitters and YTA-series temperature transmitters are cleanly routed to the CENTUM VP I/O subsystem without signal degradation.

Power Generation & Utilities: Thermal power plants and combined-cycle facilities use CENTUM VP for boiler control, turbine management, and balance-of-plant automation. The ATI3S-00 S2 provides the termination infrastructure for generator excitation feedback signals, steam flow measurements, and cooling water temperature loops, all of which require stable, low-resistance connections to maintain control accuracy across extended operating cycles.

Water & Wastewater Treatment: Municipal water treatment facilities and industrial effluent systems deploy CENTUM VP for pH control, dosing pump management, and filtration sequencing. The ATI3S-00 S2 terminal block supports the high-density I/O marshalling required when hundreds of field instruments — level sensors, flow transmitters, and valve position indicators — must be systematically terminated and routed to the DCS controller.

Pulp, Paper & Chemical Manufacturing: Continuous process industries with demanding uptime requirements rely on the structural integrity of their I/O termination layer. The ATI3S-00 S2 is suited for environments where vibration, humidity, and thermal cycling can degrade inferior terminal connections, providing long-term mechanical stability that reduces unplanned maintenance interventions and supports 12-month+ maintenance cycles aligned with planned plant shutdowns.

Mining & Metals Processing: In mineral processing and smelting operations, the ATI3S-00 S2 supports the termination of signals from conveyor belt load cells, crusher motor current sensors, and flotation cell level transmitters, enabling the CENTUM VP FCS to execute coordinated process control across geographically distributed control panels.

Q1: Is the ATI3S-00 S2 compatible with both CENTUM VP and CS 3000 systems? Yes. The ATI3S-00 S2 is designed for use within Yokogawa's CENTUM platform family, which includes both CENTUM VP (current generation) and CENTUM CS 3000 (legacy). The terminal block's mechanical form factor and electrical specifications are consistent with the I/O marshalling standards used across both platforms, making it suitable for CS 3000 maintenance projects and CENTUM VP new installations alike. Always verify the specific I/O module pairing (e.g., AAI141, ADV151) to confirm compatibility with your cabinet layout.

Q2: How does the ATI3S-00 S2 support long-term maintenance efficiency in a CENTUM VP architecture? The ATI3S-00 S2 uses a standardized screw-type termination design that allows field technicians to disconnect, inspect, and re-terminate individual field cables without disturbing adjacent wiring. This modular termination approach reduces mean time to repair (MTTR) during fault isolation, supports loop testing during commissioning, and enables systematic cable replacement during planned maintenance shutdowns. Combined with NANKMOS's 12-Month Warranty and pre-shipment testing protocol, the ATI3S-00 S2 provides a reliable, low-risk component for long-term DCS infrastructure management.
