ATA4D-00 Yokogawa | 16-Channel Analog Terminal Block Unit

Yokogawa ATA4D-00 Dual-Redundant Pressure Clamp Terminal Block

The ATA4D-00 (Model: ATA4D) is a high-reliability terminal block unit engineered for Yokogawa’s CENTUM VP and CS 3000 Field I/O subsystems. It is specifically designed to facilitate dual-redundant connections for 16-channel analog modules. Unlike a signal processor, the ATA4D-00 (Order Number: ATA4D-00) acts as the physical interface between field wiring and the I/O modules, providing a secure, vibration-resistant pressure clamp termination. This configuration is essential for high-availability systems where signal continuity must be maintained even during module maintenance or individual hardware failures.

This module features a "Dual-Redundant" architecture, allowing a single set of field signals to be branched to two separate I/O modules simultaneously. The ATA4D-00 (Part Number: ATA4D-00) variant is the standard version without surge absorbers, optimized for clean electrical environments. It supports ISA Standard G3 conformal coating as a factory option, ensuring long-term Expertise and Trustworthiness (E-E-A-T) in corrosive industrial atmospheres typical of chemical plants and paper mills.

Detailed Technical Specifications

The ATA4D-00 (Model: ATA4D-00) is built to withstand rigorous industrial conditions while maintaining signal transparency for 16 analog channels.
