CC-TAOX01 Analog Output IOTA Module
The Honeywell CC-TAOX01 is a non-redundant analog output IOTA board. It drives 4-20 mA field loops from a 24 Vdc supply. The board carries a conformal coating for harsh plant air. It works up to 60 degrees C. Part number 51308351-175 identifies this coated build. The unit is 6 inches in size. It slots into Honeywell IOTA positions and passes loop signals to field devices. Engineers use it where redundant AO cards are not required. The coated surface resists humidity, sulfur, and dust. This board fits process loops in refineries, chemical plants, and utilities. Each loop carries a standard 4-20 mA signal to valves, positioners, and transmitters. The card keeps signal drift low and wiring simple. It is a direct fit for legacy Honeywell control systems.

FAQ
Q: Is the CC-TAOX01 redundant?
A: No. This is the non-redundant build. Pick a redundant board only if your rack and loop design requires it.
Q: What does the coated version protect against?
A: The conformal coating resists humidity, dust, and corrosive plant air. It keeps the board working up to 60 C.
Q: How do I confirm this board fits my rack?
A: Send us your rack model and the old part number. We check fit and firmware before shipping.
Q: My loop reads wrong current. What should I check first?
A: Check loop wiring and field device terminals first. Then swap in a known good board to isolate the fault.
Q: How do I choose between coated and uncoated AO boards?
A: Choose coated for humid, dusty, or corrosive sites. Choose uncoated only for clean, climate-controlled cabinets.
