Product Overview

The ATR8S-00 (Model: ATR8S-00) is a high-precision pressure clamp terminal block designed as a specialized interface for Yokogawa’s CENTUM VP and CS 3000 Field I/O (FIO) subsystems. It serves as the dedicated physical termination point for 8-channel temperature input modules, enabling the secure connection of Resistance Temperature Detector (RTD) and Thermocouple (TC) signals. This ATR8S-00 (Order Number: ATR8S-00) Style S2 revision is optimized for single (non-redundant) configurations, offering a compact, vibration-resistant footprint for mission-critical thermal monitoring.

The technical design of the ATR8S-00 (Part Number: ATR8S-00) utilizes a spring-loaded pressure clamp mechanism instead of traditional screw terminals. This engineering choice eliminates the risk of wire loosening caused by thermal cycling or mechanical stress, which is vital for maintaining high accuracy in low-voltage signal environments. The unit provides a gas-tight seal for sensitive thermal inputs, effectively minimizing contact resistance and electrical noise in demanding plant environments such as chemical reactors, turbine bearing monitoring, and refinery process control.

Detailed Technical Specifications

The ATR8S-00 ensures signal transparency and mechanical durability for multi-point temperature acquisition.
