Honeywell CC-TAIX01 51308363-175 Series C Analog Input Module

Honeywell CC-TAIX01 Analog Input Module (51308363-175)

The Honeywell CC-TAIX01 (Manufacturing Part Number: 51308363-175) is a 16-channel, non-redundant High-Level Analog Input (HLAI / HART AI) Input Output Termination Assembly (IOTA) designed for the Honeywell Experion® Process Knowledge System (PKS) Series C architecture. Engineered to interface field instrumentation directly with Series C C300 controllers and I/O modules, the CC-TAIX01 assembly conditions, routes, and isolates single-ended and differential 4–20 mA current loops, high-level voltage inputs, and HART digital communication protocols.

From an automation and marine engineering standpoint, this module provides the frontline electrical termination and signal integrity required in high-vibration, high-EMI environments such as marine propulsion monitoring, offshore production skids, dynamic positioning power plants, and industrial process refineries. The board features conformal coating, galvanic field-side isolation, integrated loop-power distribution fuses, and precision shunt resistors designed to prevent system interruption under severe thermal and electrical cycling.

Technical Specifications

Key Features

1. 16 Isolated High-Precision Input Channels: Accepts standard 4–20 mA current loop, 1–5 VDC, and HART pass-through instrumentation across 16 field channels without cross-channel cross-talk.
2. Point-to-Point HART Signal Integration: Supports bidirectional digital communication between smart field devices and Experion Asset Management software over the analog loop.
3. Industrial Class I, Div 2 / Zone 2 Certified: Fully rated for non-incendive operation in hazardous locations with non-sparking electrical containment.
4. Integrated Overcurrent and Transient Suppression: Onboard fusing and MOV clamping protect sensitive C300 I/O processing modules from field line surges, lightning transients, and earth loops.
5. High-Density DIN-Rail / Carrier Mounting: Compact 6-inch form factor snaps onto standard Series C carrier channels with screw-clamp terminal blocks for rapid cable termination.

Pro-Engineer Tip:

Marine ETOs often run into a “hidden” failure mode with the Series C hardware: fretting corrosion on the gold-plated pins that connect the module to the IOTA. In places with a lot of vibration, like a steering gear room or near a turbocharger, tiny motions wear away the plating, leaving behind a thin coating of oxide that doesn’t transmit electricity. This shows up as “noisy” analog signals or spikes that happen at random in the HMI. If you detect signal changes that don’t match what is really going on with the machine, don’t just replace the transmitter. Instead, reseat the CC-TAIX01 and use a high-quality, non-conductive contact cleaning to stabilize the impedance.

Frequently Asked Questions

What is the difference between Honeywell CC-TAIX01 and CC-TAIX11?

The CC-TAIX01 (51308363-175) is a non-redundant single-module 16-channel Analog Input IOTA, whereas the CC-TAIX11 (51308365-175) is a redundant IOTA carrier that accepts two paired I/O modules (CC-PAIX01/CC-PAIH01) to provide automated, bump-less hardware failover.

Can the CC-TAIX01 module pass HART digital signals to the Experion DCS?

Yes. When paired with the CC-PAIH01 (HART Analog Input Module), the CC-TAIX01 IOTA transparently carries HART FSK (Frequency Shift Keying) digital modulation simultaneously with the 4–20 mA baseband signal, enabling remote device calibration, diagnostics, and monitoring in Experion PKS.

How do I configure channels on the CC-TAIX01 for voltage inputs instead of 4–20 mA current?

Voltage inputs (such as 0–5 V or 1–5 V) do not require loop current termination. For direct voltage inputs, field wiring connects across the positive input and common ground without applying loop power, and channel parameters are defined directly in the Experion Control Builder software.

Does the CC-TAIX01 come with conformal coating for marine and offshore installations?

–Yes. Genuine Honeywell Series C IOTA assemblies feature factory-applied conformal coating complying with ISA-S71.04 Class G3 harsh environment standards, safeguarding PCB traces against moisture, salt fog, hydrogen sulfide, and sulfur dioxide exposure.
