The TC-OAV081 is an 8-channel analog output (AO) module designed for the Honeywell Experion PKS Series C I/O platform. It delivers high-precision current and voltage outputs for modulating field devices such as control valves, VFDs, and dampers.
Each output channel is fully isolated to prevent ground loops and signal interference in electrically noisy industrial environments. The module supports both current (0–21 mA) and voltage (±10.4 VDC) output modes, enabling flexible integration into diverse control strategies.
Engineered for reliability, the TC-OAV081 incorporates integrated overvoltage protection capable of withstanding continuous 24 VAC/VDC exposure at room temperature. It interfaces with the TC-TBNH 20-position terminal block for secure field wiring and is optimized for thermal efficiency within Series C I/O assemblies.

Control Valve Positioning – Precise modulation of flow control valves.
VFD Speed Control – Analog speed reference outputs.
Chemical Dosing Systems – High-resolution output for metering pumps.
Pressure & Temperature Regulation – Stable loop control in PID applications.
High-Integrity Process Loops – Applications requiring fine signal granularity and isolation.
Is channel-to-channel isolation provided?
Yes. Each of the eight output channels is independently isolated to prevent ground loops and ensure signal integrity.
What happens during an overvoltage event?
The module includes built-in 24 VAC/VDC continuous overvoltage protection. If sustained abnormal conditions occur, integrated diagnostics report the fault to the Experion controller for corrective action.
