Product Description

The 8C-TAOXB1 (Part Number 51307137-175) is a high-precision Analog Output (AO) module engineered for the Honeywell Experion PKS Series 8 I/O family. It is designed to regulate continuous process variables by delivering isolated 4–20 mA current signals to field actuators such as control valves, dampers, and motor speed controllers.

Featuring advanced 16-bit digital-to-analog conversion, the 8C-TAOXB1 ensures high-fidelity signal output with minimal thermal drift. Its Series 8 vertical architecture optimizes cabinet airflow and simplifies maintenance access. The module also includes onboard diagnostics, such as open-loop detection and output read-back verification, ensuring that commanded signals match actual field outputs—critical for high-integrity control applications in demanding industries.
