8U-PAONA1 Honeywell Series 8 Analog Output Module

The Honeywell 8U-PAONA1, also cataloged as the 8U-PAONA1 Analog Output Module, operates as a dedicated hardware component for 16-channel analog current signal output within Honeywell Experion PKS control system platforms.

Hardware Specifications

4-20 mA Loop Control and Redundant Channel Isolation

The Honeywell 8U-PAONA1 integrates high-resolution digital-to-analog conversion architecture to output precise 4-20 mA signals into external loop loads ranging from 50 to 800 Ohm. Interfacing directly with Experion PKS controllers, the module incorporates open-circuit protection and diagnostic monitoring on each channel. Built-in redundancy switchover hardware ensures output signal transition within 10 ms during primary module failover, shielding sensitive final control elements from signal loss. Internal isolation circuits protect central processing logic from common-mode voltage spikes and field-induced noise.

Frequently Asked Questions

Q: Does the 8U-PAONA1 module support Removal and Insertion Under Power (RIUP)?

A: Yes, the 8U-PAONA1 features a hot-swappable architecture that allows module removal and installation without powering down the carrier rack or system.

Q: What is the maximum switchover delay in redundant configurations?

A: The redundant switchover logic maintains output continuity with a maximum transfer gap of 10 ms during a primary module fault.

Q: What field load resistance range can each analog output channel drive?

A: Each channel is specified to drive field load impedances between 50 Ohm and 800 Ohm across its full operating current range.

Field Installation Guidelines

1. Mount the module firmly into its designated Experion PKS Series 8 I/O slot until the locking latches click, ensuring proper connection to the backplane ground interface.
2. Verify that cabinet Earth ground leads are securely bonded to the main cabinet bus bar using low-impedance grounding conductors.
3. Route 4-20 mA output loop field wiring using shielded twisted-pair cables, keeping signal runs isolated from high-voltage AC power lines.
4. Terminate signal cable drain shields strictly at a single enclosure ground bar point to eliminate ground potential loop currents.
5. Ensure field loop load resistance remains strictly within the 50 to 800 Ohm range before energizing the output channels.
