Product Overview
The Yokogawa AAV144-S50 is a high-performance analog input module designed for Centum VP control systems.
This module processes up to 16 voltage signals with complete channel-to-system electrical isolation.
It supports standard voltage ranges of -10 V to +10 V and 1 V to 5 V.
Engineers select the AAV144-S50 because it offers rapid data updates and high noise immunity in industrial environments.
The standard design does not feature explosion protection, making it ideal for safe-area control cabinets.
