Product Overview
The Yokogawa AED5D-01 is a field wiring terminal board engineered for long-term stability and signal integrity in Yokogawa Distributed Control Systems. It functions as an interface layer between plant-side instruments and DCS I/O modules, allowing structured, traceable, and service-friendly signal termination for both analog and discrete signals.
Designed to align with Yokogawa’s CENTUM architecture, this terminal board emphasizes electrical safety, mechanical robustness, and ease of maintenance in continuous-process environments.
Core Functionality
The AED5D-01 terminal board provides a consolidated termination point for multiple field signals, minimizing wiring complexity inside control cabinets. By separating field wiring from system modules, it reduces the risk of damage during commissioning or maintenance and improves overall system uptime.
Key functional roles include signal termination, grounding organization, channel separation, and secure routing of field cables into Yokogawa I/O systems.

Design and Reliability Features
The AED5D-01 is built for continuous-duty operation in industrial control rooms and field cabinets. Its layout supports clear wire identification, stable clamping force, and effective grounding paths. Materials and terminal spacing are selected to maintain insulation performance under vibration, temperature variation, and long operating cycles.
Typical Application Scenarios
In process industries, the terminal board is commonly used for connecting pressure, temperature, flow, and level transmitters to DCS I/O cards. In power generation and utilities, it supports reliable routing of monitoring and protection signals. Manufacturing facilities use it to organize discrete sensors and actuator wiring within centralized control panels.
Frequently Asked Questions
Q: Is the AED5D-01 suitable for both analog and digital signals?
A: Yes. The terminal board is designed to accommodate mixed analog and discrete signal wiring within the same assembly, subject to system design rules.
Q: Can this terminal board be replaced without disturbing the I/O module?
A: Field wiring remains on the terminal board, allowing safer maintenance and module replacement with minimal rewiring.
Q: Is it compatible with CENTUM VP systems?
A: Yes. The AED5D-01 is intended for use with CENTUM VP and earlier CENTUM platforms when installed in the correct I/O configuration.
