HONEYWELL TC-OAV081 Product Specification
1. Product Overview
The HONEYWELL TC-OAV081 is a high-reliability analog output module designed for Honeywell Experion PKS (Process Knowledge System) and TPS (Total Plant Solution) control systems. As a core control execution component in industrial automation, it specializes in converting digital control signals from the system into 4–20 mA analog outputs, enabling precise regulation of field devices such as control valves, actuators, and variable frequency drives (VFDs). This module is widely applied in oil & gas, petrochemical, chemical, and power generation industries, ensuring stable process control and optimized production efficiency.
Engineered with robust isolation design and advanced signal conditioning technology, the TC-OAV081 delivers consistent output accuracy and strong anti-interference performance, maintaining stable operation under harsh industrial conditions (electromagnetic interference, voltage fluctuations). It complies with IEC 61131-2 and other industrial standards, ensuring seamless integration with Honeywell’s control systems and reliable data transmission.

3. Key Features
3.1 High Precision Output
With ±0.05% full-scale accuracy and minimal temperature drift, the module ensures precise and stable analog output, enabling fine control of field devices. This level of precision is critical for processes requiring strict parameter control, such as chemical reaction temperature regulation and oil pipeline pressure control.
3.2 Robust Isolation & Anti-Interference
Channel-to-channel and channel-to-system isolation designs effectively prevent signal cross-talk and electromagnetic interference (EMI) from industrial environments. The module complies with IEC 61000-4 EMI standards, ensuring reliable operation in high-noise scenarios like power plants and heavy industrial workshops.
3.3 Comprehensive Diagnostics & Easy Maintenance
Built-in self-diagnostic functions monitor output circuit faults, overload, and power supply anomalies in real time, sending alarm signals to the control system for timely troubleshooting. The plug-and-play design and standardized backplane interface simplify module replacement and maintenance, reducing equipment downtime.
