Honeywell CC-PAOH01 HART Analog Output Module

Configured for precise analog signal execution in Experion PKS Series C platforms, the Honeywell CC-PAOH01 (CC-PAOH01 HART Analog Output Module) provides direct physical/electrical execution.

Hardware Specifications

4-20 mA HART Loop Protocol and Channel Isolation

The module converts internal controller commands into precise 4-20 mA DC current signals to drive modulating field actuators while supporting superimposed HART communication protocols for smart device diagnostics. Integrated channel-to-channel optical and galvanic isolation barriers safeguard internal control electronics from ground loop disturbances and external voltage transients. Furthermore, onboard cold junction compensation (CJC) and continuous output readback circuitry maintain signal linearity and thermal stability across adjacent measurement loops.

Frequently Asked Questions

Q: What is the maximum resistive load supported by each output channel under standard operating voltage?

A: Each output channel supports a maximum resistive load of 800 ohm when powered by a 22-28 V DC supply.

Q: How does the module execute failure behavior during a system communication loss?

A: Output failure behavior is user-configurable to either hold the last commanded value or transition immediately to a predefined safe state.

Q: Does the hardware support redundant I/O rack configurations?

A: Yes, the module interfaces directly with compatible IOTA models such as CC-TAOX01 and CC-GAOX11 to execute redundant switchovers within a 10 ms window.

Field Installation Guidelines

Ensure rack power supplies are fully de-energized prior to inserting the module into the designated Series C chassis slot. Align the module card along the backplane guide rails and press firmly until the mechanical retention latches engage completely. Route analog signal wiring through dedicated metallic conduits separated from high-voltage power lines, and ground all cable shielding directly at the main panel earth bus bar.
