Product Description

The ATT4D-00 S2 is a high-integrity terminal interface designed for Yokogawa CENTUM series control systems. It provides a dual-redundant wiring interface for critical process instrumentation, ensuring continuous signal flow even if one path fails.

With robust pressure clamp terminations, this module delivers gas-tight, vibration-resistant connections, maintaining signal reliability in demanding industrial environments. The S2 revision incorporates enhanced materials and contact plating for improved corrosion resistance and long-term conductivity.

Key Features

• Dual-Redundant Architecture: Supports two independent signal paths for fail-safe operation

• Precision Pressure Clamps: Spring-loaded clamps eliminate the need for periodic re-tightening

• High-Density Integration: Compact design allows efficient mounting within Yokogawa field control stations

• Enhanced S2 Revision: Improved mechanical tolerances, insulating materials, and corrosion-resistant contacts

Technical Specifications

Industrial Applications

The ATT4D-00 S2 is widely used in mission-critical industries, including:

• Offshore oil and gas platforms

• Nuclear power generation

• Chemical refineries

It is primarily deployed to terminate signals from pressure, flow, and temperature transmitters, ensuring system reliability and safety.

Technical FAQ

Q: What is the primary advantage of the S2 revision?
A: The S2 version features improved mechanical tolerances and insulating materials, providing superior protection against electrical tracking, corrosion, and environmental degradation.

Q: Does this terminal block require special tools for wiring?
A: No. The spring-loaded pressure clamp allows quick, secure wire insertion using a standard flat-head screwdriver, reducing installation time while ensuring a gas-tight connection.
