Yokogawa AAI841-H50 Analog I/O Module - Advanced 8-Channel HART-Enabled Signal Processing

The Yokogawa AAI841-H50 Analog I/O Module delivers precision signal conditioning for industrial process control systems requiring reliable 4-20mA current loop management with integrated HART protocol support. Engineered for demanding automation environments, this module provides eight configurable input/output channels with exceptional accuracy and dual-redundant architecture compatibility.

Technical Specifications

Channel Configuration: 8 analog I/O channels (configurable as input or output)
Signal Type: 4-20mA DC current loops with HART communication overlay
Accuracy: ±0.1% of span (typical operating conditions)
Isolation: Channel-to-channel and channel-to-bus isolation for enhanced noise immunity
HART Protocol: Fully compliant with HART 7 specification for digital communication
Redundancy Support: Compatible with dual-redundant control configurations
Operating Temperature: -40°C to +70°C ambient
Power Consumption: Maximum 5W per module

Application Scenarios

The AAI841-H50 excels in process industries where precise analog signal management is critical. Deploy this module in oil & gas refineries for transmitter signal acquisition, chemical processing plants for flow and pressure monitoring, power generation facilities for temperature control loops, and water treatment systems for level measurement integration. The HART communication capability enables remote device configuration and diagnostics without interrupting the 4-20mA control signal.

System Integration & Solutions

Seamlessly integrates with Yokogawa CENTUM VP, ProSafe-RS, and STARDOM control platforms. The module's hot-swappable design minimizes downtime during maintenance, while built-in self-diagnostics continuously monitor channel health and signal integrity. Advanced filtering algorithms suppress electrical noise in harsh industrial environments, ensuring stable process control even near high-power equipment or motor drives.

Key Advantages

Simultaneous analog control and digital HART communication on each channel
Field-proven reliability in safety-critical SIL 2 applications
Simplified wiring with universal input/output channel configuration
Comprehensive diagnostic data accessible via HART commands
Backward compatible with legacy 4-20mA devices while supporting modern smart transmitters
