Yokogawa AAV144-S50/A4S10 Analog Input Module

Overview

The AAV144-S50/A4S10 is a versatile voltage input module designed to handle 16 isolated input channels for 1 to 5 V or -10 to 10 V signals. This module is engineered for use in dual-redundant configurations, ensuring continuous operation even in critical applications. With excellent accuracy, fast data update, and outstanding isolation characteristics, the AAV144 is ideal for industrial automation systems that require high-precision analog measurements.

Key Features

• 16 Isolated Input Channels: Allows for precise measurement with protection against electrical noise.
• Wide Input Range: Accepts both 1 to 5 V and -10 to 10 V signals.
• Accuracy: ±4 mV (for 1 to 5 V signals) and ±20 mV (for -10 to 10 V signals).
• Fast Data Update: 10 ms update period for real-time performance.
• Exceptional Isolation: Withstands 1500 V AC isolation between input and system for enhanced safety.
• Flexible Configuration: Ideal for use in both standard and dual-redundant configurations.
