Product Description

The Yokogawa AAV144-S53/K4A00 is a high-performance analog input module designed for the CENTUM VP distributed control system. It provides 16 fully isolated channels for accurate acquisition of 4–20 mA process signals, supporting high-density signal monitoring in industrial control cabinets.

The S53 suffix denotes a standard module with conformal coating (ISA G3 compliant) for enhanced protection against corrosive gases and harsh atmospheric conditions. The K4A00 designation identifies the terminal block or connector configuration, ensuring compatibility with specific wiring terminations. With high-speed 10 ms data refresh and ±0.1% full-scale accuracy, the module ensures precise and reliable signal acquisition for critical control loops.

Technical Specifications

Application Scenarios

The AAV144-S53/K4A00 is widely used in mission-critical process control applications, including:

• Oil and gas production facilities

• Petrochemical plants

• Power generation plants

It monitors process variables such as pressure, flow, temperature (via transmitters), and level, while the 16-channel high-density layout optimizes cabinet space and wiring efficiency.

FAQ

Q: What does the /K4A00 suffix indicate?
It specifies the terminal block or connector configuration of the module, ensuring compatibility with particular wiring termination styles in the control cabinet.

Q: Does the AAV144-S53/K4A00 support redundancy?
Yes. Modules can be installed in redundant pairs within CENTUM VP FIO nodes, enabling uninterrupted signal acquisition even if one module fails.
