Product Overview

The Honeywell CC-TAOX11 (PN: 51308353-175) is a redundant 16-channel Analog Output IOTA for Experion PKS Series C. It hosts two AO modules in a 1:1 redundant configuration, ensuring continuous control signal delivery to valves and actuators even during module failure.

Designed for hot-swap maintenance, the CC-TAOX11 allows module replacement without disturbing field wiring. Its G3 conformal coating protects against corrosive industrial environments.

Technical Data

Key Features:

• Seamless Redundancy: Millisecond switchover between primary and secondary modules.

• HART Pass-through: Supports full HART communication with CC-PAOH01 modules.

• Robust Terminals: Secure, vibration-resistant field connections.

• Streamlined Maintenance: Field wiring fixed to IOTA; modules can be serviced without disconnecting wires.

Typical Applications

• Refinery Pressure Control: Critical flare valves and pressure-reducing stations.

• Turbine Speed Control: Redundant analog feedback for steam turbine governors.

• Chemical Reactor Feed: Flow control for reactive chemicals.

• Offshore Platforms: Redundant control for subsea valves and safety actuators.

FAQ

Q1: Difference between CC-TAOX11 and CC-TAON11?
A1: CC-TAOX11 is redundant (two modules); CC-TAON11 is non-redundant (single module).

Q2: Does it support HART communication automatically?
A2: The IOTA is transparent to HART; HART-capable modules like CC-PAOH01 are required.

Q3: Is the -175 version suitable for corrosive environments?
A3: Yes, G3 conformal coating protects against harsh environments (H₂S, Cl₂) per ISA-S71.04.

Q4: Can I install one module now and add the redundant module later?
A4: Yes, the IOTA operates in non-redundant mode with one module; redundancy can be enabled later without downtime.
