The 8C-TAOXA1 (Part Number 51307135-175) is a high-performance Analog Output (AO) module designed for the Honeywell Experion PKS Series 8 I/O architecture. It provides 16 channels of isolated 4–20 mA current outputs, enabling precise control of field devices such as control valves, actuators, and variable speed drives.
The module utilizes advanced digital-to-analog conversion technology to deliver high-accuracy output with minimal thermal drift. Its Series 8 vertical form factor enhances cabinet space utilization and improves thermal dissipation. Equipped with comprehensive onboard diagnostics—including open-loop detection and output read-back verification—the 8C-TAOXA1 ensures that commanded signals accurately match field outputs, supporting high-integrity control loops in critical process environments.
