Product Description
The AAV144-S00/K4A00 is a high-density analog input module engineered for the Yokogawa CENTUM VP distributed control system (DCS). This module provides 16 channels of isolated current or voltage inputs, designed to interface with field transmitters in high-reliability industrial environments. Each channel features individual galvanic isolation to prevent ground loops and enhance signal integrity across the process loop.
Equipped with the K4A00 suffix, this specific configuration includes the necessary pressure-clamp terminal block for direct field wiring, ensuring a secure and vibration-resistant connection. The module supports a wide dynamic range and high-resolution signal conversion, making it suitable for critical monitoring of pressure, temperature, and flow transmitters.
