Product Description
The AET4D-00 is a high-precision thermocouple signal termination board designed for the CENTUM VP Distributed Control System (DCS) from Yokogawa Electric Corporation.
This terminal board functions as the physical interface between field thermocouple sensors and DCS I/O modules, such as the AAI143 or AAT141 analog input modules. It is widely used in thermal process industries where accurate temperature measurement is critical for control stability.
The AET4D-00 supports both single and dual-redundant I/O configurations, enabling high system availability and minimizing process downtime. It includes integrated Cold Junction Compensation (CJC) circuitry to maintain high measurement accuracy despite ambient temperature fluctuations.
The board is constructed for harsh industrial environments and is commonly deployed in refineries, chemical processing plants, and power generation facilities where long thermocouple cable runs are required.

Operational Capabilities
The AET4D-00 is designed to reduce electromagnetic interference (EMI) and minimize signal degradation during long-distance thermocouple wiring.
Key features include:
-
Independent channel calibration capability
-
High common-mode noise rejection
-
Plug-and-play KS1 cable integration for simplified installation
-
Dual output path support for redundant safety architectures
These features make the board particularly suitable for high-precision temperature control loops in continuous process manufacturing.
FAQ
Does this terminal board support RTD sensors?
No. The AET4D-00 is optimized specifically for thermocouple and millivolt signals. For RTD measurement, the AER4D terminal board series should be used instead.
What is the difference between AET4D-00 and AET4D-05?
The AET4D-00 is the base configuration without integrated surge suppression. The -05 variant typically represents a hardware revision or regional terminal layout variation.
Can I use this board for redundant I/O modules?
Yes. The AET4D-00 includes dual KS cable outputs on the rear side, allowing field signals to be simultaneously transmitted to two I/O modules for redundancy and higher system availability.
