AAI141-H00/CCC01 CENTUM VP Analog Input Module | Yokogawa

Product Overview

The Yokogawa AAI141-H00/CCC01 acts as a high-density data acquisition interface for CENTUM VP field control stations. This module processes 16 channels of 4 to 20 mA DC signals, providing critical process variables to the controller with high precision. By incorporating the HART digital communication protocol, the module enables remote device configuration and diagnostic data pass-through. We provide this unit as 100% Brand New and Original, complete with the factory-installed connector cover for MIL cable security.

Part Number Breakdown

Technical Specifications

Engineering Advantages

• HART Integration: The module overlays digital diagnostic data onto the analog 4-20 mA signal. This allows maintenance teams to monitor instrument health and adjust parameters remotely without interrupting the process loop.

• Enhanced Connection Security: The /CCC01 option provides a specialized cover for MIL-standard cables. This mechanical guard prevents accidental disconnection in high-vibration environments and protects the sensitive pin interface from dust and debris.

• High-Precision Conversion: With an accuracy rating of $\pm16$ µA, the AAI141-H00 ensures superior measurement fidelity. This precision directly improves the performance of PID control loops in chemical and power generation applications.

• Compact Thermal Profile: Weighing only 0.2 kg, the module maintains low power consumption and heat dissipation. This allows engineers to populate I/O nests to maximum capacity without exceeding the thermal limits of the cabinet.

FAQs

• Does this module provide power to the field transmitters (2-wire)?

  The AAI141 is a non-isolated current input module. While it receives 4-20 mA signals, you must verify your wiring architecture (2-wire vs. 4-wire) against the specific terminal board and power supply configuration used in your CENTUM rack.

• Can I use this module with standard HART-7 field devices?

  Yes. The "-H" suffix indicates full support for HART digital communication, allowing the module to act as a gateway for device management software like PRM (Plant Resource Manager).

• What is the primary benefit of the /CCC01 option?

  The /CCC01 (Model ACCC01) cover secures the MIL connector. It serves as a strain relief and physical barrier, ensuring that high-density wiring stays seated during seismic events or routine cabinet maintenance.

• Is this unit hot-swappable?

  CENTUM VP hardware supports the replacement of I/O modules while the system remains powered. However, always follow Yokogawa’s prescribed "Hot-Swap" procedures to ensure the control station maintains redundant data integrity during the transition.
