Product Overview

The Yokogawa AAV144-S00 serves as a core high-density analog input component for the CENTUM VP, CS 3000, and ProSafe-RS systems. This module captures analog voltage signals from field instruments—including pressure transmitters, flow meters, and temperature sensors—and converts them into high-fidelity digital data for the Field Control Unit (FCU). With 16 fully isolated channels, the AAV144-S00 eliminates ground loop interference and maintains signal stability in large-scale petrochemical, power, and utility facilities.

Condition: 100% Brand New, Factory Sealed Original.

Part Number Breakdown: AAV144 Series

Yokogawa uses a structured coding system to define the functional limits and hardware revision of the AAV144 series.

• AAV144: Base Series (Voltage Input Module, 16-channel).

• -S: Standard type for general industrial applications.

• 0: Basic configuration (Non-enhanced).

• 0: Always 0 (Standard hardware revision).

Technical Specifications

The AAV144-S00 balances rapid data processing with extreme thermal resilience for mission-critical deployments.

Engineering Advantages

• Total Channel Isolation: Individual isolation for each of the 16 channels prevents cross-talk and ensures that a localized electrical fault on one transmitter does not jeopardize the entire I/O nest. This architecture maximizes uptime in safety-critical process loops.

• Superior Thermal Performance: Unlike standard I/O modules limited to 50°C, the AAV144-S00 operates reliably between -40°C and +80°C. This extended range allows installation in remote instrument enclosures or extreme climates without requiring expensive environmental control units.

• High-Speed Loop Response: A 10 ms data update period enables the control system to react nearly instantaneously to process fluctuations. This speed proves vital for surge control in compressors and pressure regulation in volatile chemical reactors.

• Space-Efficient Marshaling: The compact 32.8 mm width allows engineers to pack high-density analog inputs into restricted cabinet spaces, reducing the total number of I/O nodes and lowering infrastructure costs.

FAQs

Q: Can the AAV144-S00 accept 4-20 mA current signals?

A: Yes. Although the module natively measures voltage, you can monitor 4-20 mA signals by installing a precision 250-ohm shunt resistor across the input terminals to convert the current to a 1-5 V signal.

Q: Is this module compatible with the older CENTUM CS 3000 platform?

A: Absolutely. The AAV144-S00 maintains full compatibility with both the legacy CENTUM CS 3000 and the current CENTUM VP platforms, facilitating seamless system expansions or hardware migrations.

Q: How does the module handle a failed input signal?

A: The AAV144-S00 includes continuous self-diagnostics and input monitoring. If a signal falls out of the designated range or a hardware fault occurs, the module triggers a system alarm to the Human Interface Station (HIS) for immediate technician intervention.

Q: Does the AAV144-S00 support redundant configurations?

A: Yes. You can install these modules in a dual-redundant configuration on the FCU backplane to ensure continuous data acquisition even if one module requires replacement.
