Description
The Honeywell 8U-PAONA1 is a 16-channel analog output module engineered for the Experion PKS distributed control system platform. It provides high-precision 4-20 mA signal transmission for critical industrial process control applications, including valve positioning, actuator regulation, and analog process control in refineries, power plants, and chemical processing facilities.
This module is designed for reliability and uptime, featuring support for hot-swapping (insertion and removal under power) to facilitate maintenance without system shutdowns. Its architecture supports redundant configurations, ensuring minimal output interruption during switchover events, which is essential for maintaining process stability in continuous manufacturing environments.
Features
- 16 independent analog output channels for 4-20 mA signal transmission.
- Supports hot-swapping for maintenance without system power-down.
- Redundancy-ready architecture with a maximum switchover gap of 10 ms.
- Configurable output range from 2.9 mA to 21.1 mA.
- Low ripple design with high-resolution digital-to-analog conversion.
- Integrated open circuit protection for enhanced diagnostic capability.
- Passive convection cooling for reliable operation in industrial cabinets.
Applications
The 8U-PAONA1 is primarily utilized in Honeywell Experion PKS environments for:
- Final control element positioning (valves and dampers).
- Analog process variable regulation.
- Distributed control system (DCS) I/O expansion.
- Critical process automation requiring redundant signal paths.

Installation Guidelines
- Ensure the module is installed in a compatible Experion PKS I/O rack.
- Power-down the specific I/O segment if required by site safety protocols, although the module supports hot-swapping.
- Ensure proper grounding of the I/O rack to minimize EMI/RFI interference.
- Use shielded twisted-pair cabling for analog signal runs to maintain signal integrity and reduce noise.
- Verify that field wiring is securely terminated and that load resistance remains within the 50-800 Ohm specification.
- Maintain adequate clearance around the module to allow for passive convection cooling.
FAQ
Is this module compatible with non-Honeywell systems?
The 8U-PAONA1 is specifically designed for the Honeywell Experion PKS platform and is not intended for use with third-party control systems.
Does this module support redundant operation?
Yes, the 8U-PAONA1 is designed to support redundant system architectures, ensuring that output interruption remains below 10 ms during a controller switchover.
Can I replace this module while the system is running?
Yes, the module supports insertion and removal under power (hot-swapping), allowing for maintenance without interrupting the overall process control system.
