Product Overview

The Honeywell CC-TAOX61 (PN: 51309152-175) is a 16-channel Redundant Analog Output IOTA for the Experion PKS Series C platform. It provides physical mounting and wiring for a redundant pair of Analog Output modules (CC-PAOH01 / CC-PAOH51).

This 12-inch IOTA is designed for high-availability control loops, ensuring uninterrupted 4–20 mA signals to field actuators. The G3 conformal coating (-175) protects against corrosive and harsh industrial atmospheres.

Technical Data

Key Features:

• Bumpless Redundancy: <10 ms switchover between primary and secondary modules.

• HART Integration: Full digital communication for diagnostics and configuration via Experion.

• Efficient Heat Dissipation: Vertical design supports natural convection for high channel density.

• Hot-Swap Maintenance: Field wiring remains untouched when replacing modules.

Typical Applications

• Refinery Throughput Control: Redundant AO signals for crude distillation valves.

• Turbine Governing Systems: Redundant control of steam or gas turbine actuators.

• Chemical Reactor Temperature: Redundant cooling water valve control in exothermic processes.

• Offshore Production: Subsea and topside valve control in corrosive environments.

FAQ

Q1: Difference between CC-TAOX61 and CC-TAOX11?
A1: CC-TAOX61 is a 12-inch IOTA with more space and better heat dissipation than smaller versions (like TAOX11), ideal for high-density or high-load cabinets.

Q2: Can this IOTA support both HART and non-HART modules?
A2: Yes, it can host standard AO (CC-PAON01) or HART-capable modules (CC-PAOH01/51). HART functionality depends on the module installed.

Q3: How do I detect a failure?
A3: The IOTA itself is passive. Module LEDs indicate failure, and Experion generates a “Redundancy Lost” alarm if communication with a module is lost.

Q4: Is it safe for Class I, Div 2 areas?
A4: Yes, when installed in a suitable enclosure with Series C modules, it is rated for hazardous locations (Class I, Div 2 / Zone 2).
