The Honeywell 8C-PAONA2 (8CPAONA2) is a high-performance Analog Output (AO) module belonging to the Experion PKS Series 8 I/O family. Engineered for precision and mission-critical reliability, this 16-channel module converts digital control commands from the C300 controller into standard 4-20 mA analog signals. The 8C-PAONA2 is primarily used to drive final control elements such as pneumatic valve positioners, variable speed drives (VSD), and dampers. As a "Series 8" component, it features a vertical, slimline design that optimizes cabinet density and promotes natural thermal convection. This specific variant is the "Non-HART" version, providing a cost-effective solution for control loops where digital field device diagnostics are not required, while maintaining the rugged G3-level environmental protection standard in Honeywell's premium I/O line.
The 8C-PAONA2 is designed to integrate seamlessly into the Experion PKS architecture, focusing on signal stability and hardware longevity.
16-Channel Density: Provides 16 independent analog output channels, allowing for high-density I/O configurations in a small physical footprint.
Series 8 Architecture: Designed to be "plug-and-play" with Series 8 IOTAs (Input Output Termination Assemblies), supporting both non-redundant and redundant configurations.
G3 Conformal Coating: The module is factory-treated with a conformal coating to protect internal circuitry against humidity and corrosive atmospheric contaminants (ISA S71.04 Class G3).
Galvanic Isolation: Features robust isolation between the I/O Link (backplane) and the field-side electronics, preventing ground loops and protecting the C300 processor from field electrical faults.
Fast Loop Response: Optimized for low-latency signal delivery, ensuring that control valve movements are synchronized with the DCS PID logic for stable process modulation.

Can the 8C-PAONA2 be used to communicate with HART-enabled valves?
While the 8C-PAONA2 can drive a HART-enabled valve positioner using a standard 4-20 mA signal, it cannot read or write digital HART data. For full HART pass-through and diagnostics, the 8C-PAOHA1 module must be used instead.
How does this module handle a loss of communication with the controller?
The 8C-PAONA2 features a configurable "Fail-Safe" state. In the event of an I/O Link failure or controller shutdown, each channel can be programmed to Hold Last Value (HLV) or go to a pre-defined safe value (e.g., 0 mA or 4 mA).
Is this module compatible with older Series A or Series C IOTAs?
No. The 8C-PAONA2 is strictly a Series 8 module and must be mounted on a Series 8 IOTA, such as the 8C-TAOXA1 (Single) or 8C-TAOXB1 (Redundant).
Output Impedance Matching: Ensure that the total loop resistance (including field wiring and the actuator/positioner impedance) does not exceed the module's maximum drive capability, typically 600 Ohms at 24 VDC. Exceeding this limit will result in "Output Low" errors.
Hot-Swap Procedure: This module supports Removal and Insertion Under Power (RIUP). When replacing a module in a redundant pair, ensure the "Secondary" LED is stable before removing the "Primary" module to ensure a bumpless transfer of control.
Shielding and Noise: Use twisted-pair shielded cable for all 16 channels. The shield should be grounded at the IOTA's grounding bar. Proper shielding is critical to prevent electromagnetic interference (EMI) from inducing "jitter" in the 4-20 mA output signal, which can lead to premature mechanical wear on valve positioners.
