Product Description

The ATR8S-10 is a specialized signal termination and distribution module designed for the Yokogawa Electric Corporation CENTUM VP and CENTUM CS 3000 control architectures.

This module functions as a high-density wiring termination interface between field instrumentation and DCS I/O modules. It is primarily used to simplify multi-core cable management while maintaining strong signal integrity for both analog and digital process signals.

The ATR8S-10 features industrial-grade screw terminal construction, providing vibration-resistant and stable electrical connections, which is critical for heavy industrial control cabinet environments. Its structured terminal layout improves wiring documentation and significantly reduces maintenance troubleshooting time.

Technical Specifications

Installation Applications

The ATR8S-10 is commonly deployed in:

• Marshaling cabinets

• Junction boxes

• Offshore platform control panels

• Refinery and petrochemical control systems

It is especially valuable in safety and audit-sensitive installations where clear wiring traceability is required for maintenance and regulatory compliance.

Typical connected field devices include:

• Process transmitters

• Control valves

• Limit switches

• Auxiliary signaling contacts

Frequently Asked Questions

Is ATR8S-10 compatible with all Yokogawa I/O cables?
The ATR8S-10 is designed to work with standard Yokogawa signal cabling, including KS-series cables, serving as the physical termination bridge between field wiring and I/O module connectors.

Does it provide surge protection?
No. The ATR8S-10 is a passive termination device. For environments requiring lightning or surge protection, external surge arrestor modules should be installed in series with the signal loop.

Is this device active or passive?
It is a passive wiring interface and does not require external power.
