The CC-TAON01 is a specialized Input Output Termination Assembly designed for Honeywell's flagship Experion Process Knowledge System (PKS) Series C platform. It handles the physical termination of up to 16 analog output loops, converting system commands into standard 4-20 mA DC current signals. Built for continuous operation in demanding environments, this IOTA provides reliable galvanic isolation, robust over-current protection, and simplified field-side terminal routing. Its optimized form factor mounts directly onto standard carriers, streamlining control cabinet layouts and lowering deployment engineering costs.

Model: CC-TAON01 (Standard Coated IOTA Module)

• Technical Parameters:

• Channel Count: 16 Output Channels

• Signal Range: 4 to 20 mA DC

• Part Number: 51306519-175 / 51304485-100

• System Interface Compatibility: CC-PAON01 Analog Output Module

• Nominal Supply Voltage: 24 V DC

• Power Dissipation: Max 1.22W at 24V DC (with 20mA loop current & 250 ohm load)

• Field Wiring Gauge Support: 12-24 AWG (Stranded or Solid)

• Calibrated Transfer Accuracy: ±20 µA at 20°C

• Maximum Connected Loop Resistance: 650 Ohms

• Key Features & Advantages:

• Direct-insertion logic structure minimizes internal point-to-point hardware jumpers.

• Designed for long-term thermodynamic stability under fluctuating control-room ambient temperatures.

• High packing density saves valuable DIN rail space inside marshalling cabinets.

• Applications:

• Automated modulating valve control in petrochemical process loops.

• Fixed current reference distribution for variable frequency drives (VFD) speed referencing.

• Boiler fan actuator position tracking systems.

• Oil & Gas Refining: Accurate positioning of critical pneumatic and hydraulic process control valves throughout crude distillation units and cracking facilities.

• Power Generation Systems: Regulating governor valves, fuel feeding drives, and cooling tower fan actuator feedback systems.

• Chemical & Pharmaceutical Processing: Managing proportional batching pumps, thermal jackets, and precise feed-rate control loops.

• Pulp & Paper Mills: Handling continuous speed references for paper machinery rollers and controlling chemical wash distribution valves.

• Q: Can the CC-TAON01 IOTA support digital HART communication?

• A: No. The CC-TAON01 and CC-TAON11 are specifically designed for standard non-HART 4-20 mA analog output signals. For HART digital protocol implementation, you must utilize the CC-TAOX01 or CC-TAOX11 IOTA variants along with a HART-enabled AO module (such as the CC-PAOH01).

• Q: What type of field fuse options are supported on this IOTA assembly?

• A: The field-side termination points can be outfitted with optional 5 x 20 mm glass fuses for individual channel overcurrent isolation, depending on Div2 / Zone 2 installation regulations.

• Q: Is the CC-TAON01 module hot-swappable during operation?

• A: Yes, when mated with a compatible Series C base and CC-PAON01 module, the physical architecture permits standard hot-swap maintenance without disrupting concurrent power loops on adjacent modules.
