Product Description

The CPY-C3-AAI543-H is a dedicated interface backplane designed for use within the Yokogawa CENTUM VP DCS. It serves as a signal conditioning and connectivity hub for AAI543 analog input modules, enabling high-density signal termination with enhanced EMI shielding and signal integrity.

By providing a stable physical and electrical interface between field wiring and I/O modules, this backplane reduces cabinet wiring complexity, optimizes space utilization, and ensures reliable transmission of critical 4–20 mA process signals.

Technical Specifications

Application

The CPY-C3-AAI543-H is commonly deployed in large-scale industrial environments requiring high-density analog signal acquisition, including:

• Oil refineries

• Chemical and petrochemical plants

• Power generation facilities

It is especially suited for applications where organized cabinet layout, long-term maintainability, and high signal reliability are critical.

Frequently Asked Questions

How does this differ from standard AAI543 wiring?
The CPY-C3-AAI543-H centralizes multi-channel field wiring, significantly reducing clutter and minimizing signal degradation compared to direct module wiring—particularly in high-vibration or EMI-heavy environments.

Is the backplane hot-swappable?
The backplane itself is a passive interface; however, it fully supports the hot-swap functionality of the Yokogawa AAI543 modules installed on it.
