Functional Role
The 8C-PAON01 converts the C300 controller’s internal digital output values into standard 4–20 mA DC current signals that drive final control elements and process instrumentation. Per Honeywell’s official Series-C I/O specification, this module is categorized as “Analog Output w/o HART (16pt)” — meaning it provides standard 4–20 mA DC outputs only; devices requiring HART protocol communication must be served by the HART-capable variant (8C-PAOHA1, P/N 51454469-275) instead.
Within the Experion PKS architecture, the module plugs into an IOTA (termination assembly) that is pre-wired to field cabling, so replacement is a simple slide-in operation without disturbing field wiring. The C300’s I/O Link supports redundant module configurations, so a hot-standby 8C-PAON01 can be paired with the primary unit for high-availability loops — a common practice on critical control outputs such as furnace fuel-valve positioning or reactor level control.
