Analog I/O Module AAI841-H50/K4A00 | Yokogawa PLC Module

Product Description

Overview

The Yokogawa AAI841-H50/K4A00 is a high-performance Analog I/O Module designed for CENTUM VP Field I/O (FIO) systems. This module provides precise acquisition of analog signals from process devices and smart transmitters, supporting 16 channels (8 inputs / 8 outputs) with HART communication for diagnostics and configuration. Its robust design ensures reliable operation in mission-critical industrial automation environments.

System Integration

• Compatible with CENTUM VP FIO systems via ESB bus / ER bus

• Integrates with ANB10D/ANB10S, ANT502, or ANR10D bus node units

• Supports HART-enabled transmitters for advanced process monitoring

• Non-isolated design for standard signal requirements
