Process Control and Analog Output Characteristics
The CC-TAOX01 uses 4-20 mA current output channels for analog actuator and final-control-element interfaces. Each of its 16 channels provides a directly settable current range from 0 mA to 21.1 mA, subject to the specified operating limits.
The output stage supports loads up to 800 ohms and provides a maximum compliant voltage of 16 V. Therefore, field loop resistance must remain within the available compliance range. The specified maximum open circuit voltage is 22 V.
The board specifies +/- 0.05% of Full Scale nominal current linearity and +/- 0.35% of Full Scale calibrated accuracy at 25 deg C, including linearity. In addition, the output temperature drift is specified as 0.005% of Full Scale/deg C.
For DCS signal integration, Honeywell process-control hardware commonly uses standardized 4-20 mA signaling. However, the supplied specifications identify this board specifically as an analog output IOTA and do not state HART communication capability. Therefore, HART functionality should not be assumed for this model.

A: The calibrated accuracy is +/- 0.35% of Full Scale at 25 deg C, including linearity. The specified output readback accuracy is +/- 4% of Full Scale.
Field Installation Guidelines
- Confirm the CC-TAOX01 51308351-175 model and termination assignment before installation.
- Verify the 24 VDC supply and observe the applicable Honeywell Series C installation requirements.
- Route 4-20 mA signal wiring separately from high-voltage power conductors where practical.
- Maintain correct polarity for each analog output loop and verify the connected load before energizing the circuit.
- Ensure the total loop resistance remains within the specified 800 ohm maximum resistive load.
- Use appropriate shield termination practices according to the site grounding design and Honeywell installation documentation.
- Check field wiring for shorts, open circuits, and unintended ground connections before commissioning.
- Confirm output current values against the connected field device after installation.
- Do not infer HART, redundancy, or hot-swap capability unless the applicable system documentation explicitly specifies those functions.
