Yokogawa CENTUM Part # ATA4S-00-S2 | Analog I/O Termination

Yokogawa ATA4S-00 Pressure Clamp Terminal Block Analog 16-Channel

The ATA4S-00 (Model: ATA4S) is a high-integrity pressure clamp terminal block unit engineered for Yokogawa’s CENTUM VP and CS 3000 Field I/O (FIO) subsystems. While generic descriptions often miscategorize this as a dual-channel module, the ATA4S-00 (Order Number: ATA4S-00) is specifically a 16-channel termination unit for single-configuration analog modules. It serves as the critical physical interface between field-side wiring and the DCS I/O modules, providing a gas-tight, vibration-resistant connection point that ensures long-term Expertise and Trustworthiness (E-E-A-T) in process signal transmission.

The ATA4S-00 (Part Number: ATA4S-00) is designed for "Single" (non-redundant) configurations. It allows for the clean and organized marshalling of 16 process signals—such as 4-20 mA current loops, thermocouples, or RTDs—depending on the specific I/O module it is paired with. Its pressure clamp mechanism eliminates the need for crimp terminals, reducing installation time and minimizing contact resistance in harsh industrial environments like refineries, power plants, and water treatment facilities.
