Product Description

High-Integrity Analog Termination Overview

The ATA4S-00 (Model: ATA4S) is a specialized 16-channel pressure clamp terminal block unit engineered for Yokogawa’s CENTUM VP and CS 3000 Field I/O (FIO) subsystems. It serves as the primary physical interface between field instruments and the DCS I/O modules. Unlike dual-channel units, the ATA4S-00 (Order Number: ATA4S-00) is designed specifically for single-configuration (non-redundant) modules, providing a robust, gas-tight, and vibration-resistant connection point for critical process signals. The pressure clamp mechanism ensures superior electrical contact without the need for crimp terminals, significantly streamlining the marshalling process in high-density automation cabinets.
