Honeywell Analog Output Module TC-OAV081

Product Overview
The TC-OAV081 (Part Number: TC-OAV081) is a high-performance analog output module in the Honeywell Experion PKS Series C I/O family. It provides eight independent channels capable of both voltage and current output, enabling precise control of field devices such as variable speed drives, control valves, and actuators.

Designed for high-speed, deterministic process control, the TC-OAV081 features an ultra-fast 25 ms update rate for all channels and advanced protection circuitry, including electronic current limiting and overvoltage protection, ensuring safe operation even in fault conditions.

Technical Specifications

Application Scenarios

• Modulating control valve positions in chemical refineries

• Speed reference signaling for Variable Frequency Drives (VFDs)

• Interfacing with analog chart recorders or secondary displays

• Providing setpoint signals to third-party standalone controllers

Frequently Asked Questions (FAQ)

Q: Can the TC-OAV081 output both voltage and current on different channels simultaneously?
A: Yes. Each channel can be individually configured for ±10.4 V voltage or 0–21 mA current, depending on the connected field device requirements.

Q: What happens if a field wire is short-circuited?
A: The module includes built-in short circuit protection, electronically limiting output current to 21 mA or less, preventing internal damage.
