The Honeywell 8U-PAOHA1 functions as a high-density analog output module with integrated HART communication for the Honeywell Series 8 I/O system. This unit delivers precise 4-20 mA signals to control valves, positioners, and other field actuators. Consequently, it combines accurate analog control with advanced HART diagnostics for enhanced process visibility.

Core Technical Specifications

We engineered the Honeywell 8U-PAOHA1 for demanding industrial applications requiring tight process regulation and device diagnostics. The table below details its essential electronic parameters:

High-Density 16-Channel Analog Output

This module features sixteen independent analog output channels in a single, space-saving unit. Each channel provides a standard 4-20 mA signal for precise control of final control elements. Therefore, the Honeywell 8U-PAOHA1 maximizes I/O density while minimizing cabinet space requirements.

Exceptional Accuracy for Critical Loops

The 8U-PAOHA1 delivers outstanding accuracy of ±0.1% of full scale across all operating conditions. Its 12-bit resolution ensures fine granularity in signal generation for precise valve positioning or speed control. As a result, critical process loops maintain tight regulation, improving product quality and consistency.

Integrated HART Communication on All Channels

Each of the 16 analog output channels supports the HART communication protocol simultaneously. This feature allows the module to send the analog setpoint while receiving digital diagnostic data from smart devices. Consequently, you can monitor valve health, perform configuration, and troubleshoot remotely without extra wiring.

Extreme Temperature Tolerance for Global Use

Honeywell designed this output module to operate reliably in an exceptionally wide temperature range of -40°C to +85°C. This specification makes it suitable for both Arctic installations and high-heat desert environments. Furthermore, it eliminates the need for climate-controlled enclosures in many outdoor applications.

Seamless Series 8 System Integration

You can install the Honeywell 8U-PAOHA1 directly into any Series 8 I/O rack alongside other input and output modules. It communicates with the controller via the Series 8 backplane, presenting HART data as standard process variables. Therefore, system engineers can access rich device diagnostics through their existing control software.

Enhanced Diagnostics for Predictive Maintenance

With HART communication built into every channel, the module continuously monitors the health of connected field devices. It can detect issues like valve stiction, plugged impulse lines, or electronics degradation early. This predictive capability allows maintenance teams to address problems before they cause process upsets.
