Product Description

The AAI841 (P/N: AAI841-H00/CCC01) is a high-density analog interface module for the Yokogawa CENTUM VP control system. It provides 8 current input channels and 8 current output channels (16 channels total), enabling simultaneous sensing and actuation within a single I/O slot.

This H-suffix module supports HART digital communication, allowing full access to smart field device data, including secondary variables and remote diagnostics. The CCC01 option adds the ACCC01 connector cover, designed for MIL-standard ribbon cable connections, offering secure, dust-resistant, and vibration-protected connectivity for field wiring.

The non-isolated (common ground) design maximizes space efficiency and cost-effectiveness, suitable for environments where external isolation is already implemented.

Technical Specifications

Application Use Cases

The AAI841-H00/CCC01 is ideal for:

• High-density control cabinets in water treatment and energy management plants

• Applications requiring MIL-standard ribbon cable connectivity, allowing rapid mass termination of 16 channels to terminal boards

• Situations where external isolation is already provided, enabling cost-effective deployment of non-isolated modules

FAQ

What is the purpose of the CCC01 (ACCC01) option?
The ACCC01 connector cover protects the MIL ribbon cable connection from dust, vibration, and accidental disconnection, ensuring secure and reliable signal transmission in industrial environments.

How does the non-isolated design impact my installation?
All connected field devices must share the same ground potential or be externally isolated to prevent ground loops, which could otherwise compromise signal accuracy.
