Honeywell CC-TAOX11 51308353-175 Redundant Analog Output Termination Assembly

The Honeywell CC-TAOX11 51308353-175, also cataloged as the CC-TAOX11 Analog Output Termination Assemblies, operates as a dedicated hardware component for driving 16-channel redundant current outputs within Experion PKS Series C networks.

Hardware Specifications

4-20 mA HART Loop Protocol Capabilities

The CC-TAOX11 IOTA operates as a passive, transparent physical layer for 4-20 mA HART loop protocol signals when populated with HART-enabled modules such as the CC-PAOH01. Physical terminal isolation prevents cross-channel interference during continuous analog signal generation. Internal bus traces route primary and secondary module pathways through dedicated decoupling circuits, enabling millisecond switchover execution between redundant active and standby channels without disturbing analog current continuity to downstream field actuators.

Frequently Asked Questions

Q: Can the CC-TAOX11 IOTA operate with only a single AO module installed initially?

A: Yes, the IOTA functions in non-redundant mode with a single active module installed. A secondary redundant module can be inserted into the vacant slot later without disrupting power or field signals.

Q: How does the physical wiring termination design support field hot-swapping?

A: Field wiring connects directly to the screw terminals on the baseplate assembly. Modules seat into designated card-edge connectors on the IOTA, allowing physical module extraction and replacement while field wiring remains undisturbed.

Q: What is the main distinction between the CC-TAOX11 and the CC-TAON11 termination assemblies?

A: The CC-TAOX11 features dual module slots configured for 1:1 hardware redundancy, whereas the CC-TAON11 provides a single slot for non-redundant analog output applications.

Field Installation Guidelines

• Vibration and Seating Check: Verify that the IOTA baseplate is firmly attached to the enclosure mounting rails. Ensure module retention screws or latching clips fully lock both primary and secondary modules into place.
• Conformal Coating Inspection: Confirm that the G3-rated conformal coating on the printed circuit board remains intact prior to installation in harsh chemical atmospheric environments.
• Shield Grounding: Terminate all individual channel wire shielding to the local cabinet earthing bar. Maintain a single-point grounding strategy to prevent loop ground currents from introducing signal offset.
• Terminal Torque: Tighten all field wiring screw terminals to standard industrial torque specifications to maintain solid physical contact and prevent connection degradation under ambient vibration.
