Product Description
The AAI143-H50/A4S00 is a high-density FIO analog input module designed for the Yokogawa CENTUM VP distributed control system. It supports 16 isolated 4–20 mA DC input channels and includes HART digital communication, allowing diagnostic data and remote instrument configuration to pass through without affecting the primary analog signal.
This configuration includes the /A4S00 option, supplying a factory-installed ATA4S-00 pressure clamp terminal block. This enables direct field wiring at the module face, improving connection integrity and simplifying installation within the I/O node. With a fast 10 ms update cycle and strong channel-to-system isolation, the AAI143-H50/A4S00 is optimized for mission-critical process monitoring where accuracy and uptime are essential.
