Product Description
The AAI143-H50/A4S10 is a high-density, isolated analog input module for Yokogawa CENTUM VP and FIO systems. It features 16 fully isolated channels for 4–20 mA signals, ensuring maximum immunity to ground loops and EMI. The H50 specification enables HART digital communication, allowing acquisition of both primary process variables and secondary device diagnostics.
The /A4S10 terminal interface provides a secure, streamlined pressure-clamp connection for efficient field wiring.
Ideal for mission-critical process loops, it ensures high reliability and precise signal monitoring.
