HONEYWELL CC-TAIX51 Conformal Coated Analog Input IOTA Block

Description

Key Technical Specifications

Product Introduction & Supply Chain Strategy

The Honeywell CC-TAIX51 is a 16-channel non-redundant Analog Input I/O Termination Assembly (IOTA) featuring heavy-duty conformal coating, specially built for the Experion PKS Series C system. Functioning as the physical termination gateway between field transmitters and Series C logic, the CC-TAIX51 features screw terminals, integrated loop power distribution, and the mounting receptacle for Analog Input cards (such as CC-PAIX01 or CC-PAIH51). Its Class G3 conformal coating shields sensitive trace networks and solder contacts against airborne corrosives, hydrogen sulfide, and high humidity in harsh environments like offshore rigs, chemical plants, and wastewater facilities.

Securing the CC-TAIX51 as New Surplus stock provides immediate operational security and bypasses multi-week OEM fabrication lead times. This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability. Avoiding second-hand or non-coated base plates prevents corrosion-induced signal degradation, cracked terminal blocks, and short circuits in harsh environments. Maintaining a verified New Surplus CC-TAIX51 on-site ensures fast field restoration without compromising environmental protection ratings.

Installation & Configuration Guide

Stage 1: Pre-Installation (Prep & Safety)

1. Execute full Lock-Out/Tag-Out (LOTO) on the incoming 24 VDC power feeder powering the targeted Series C carrier rack.
2. Ground yourself using an ESD wrist strap attached to an unpainted chassis point before handling the IOTA.
3. Verify field cable tags, channel polarity assignments, and shield grounding wires against control loop schematics.

Stage 2: Removal

1. Unfasten the top and bottom retaining screws on the mounted Analog Input card (e.g., CC-PAIX01) and pull it straight off the CC-TAIX51 socket.
2. Unplug or unscrew field wiring leads from the terminal block connectors, recording the wire numbers for accurate landing later.
3. Unlatch the DIN rail locking clips or carrier frame mounting hardware, then slide the CC-TAIX51 base off the mounting rail.

Stage 3: Installation (Clone & Seat)

1. Unpack the replacement New Surplus CC- assembly from its protective anti-static bag.
2. Secure the CC- onto the DIN rail or carrier frame, tightening all mechanical fasteners securely.
3. Reconnect field transmitter wires to their corresponding screw terminals (+, −, and Shield) and torque screws to 0.5 Nm.

Stage 4: Power-On & Testing

1. Align the Analog Input module with the CC- guide rails, push firmly until backplane connectors seat, and tighten retaining screws.
2. Re-apply 24 VDC loop power to the carrier rack. Verify that transmitter voltage across active terminal channels reads between 21.6 and 26.4 VDC.
3. Check Experion Control Builder to ensure all 16 channels communicate cleanly without backplane fault codes or channel break alarms.

Firmware/Software Versions & Upgrade Notes

• Passive Base Architecture: The CC- is a physical termination assembly containing no microprocessors or programmable firmware. Software compatibility depends entirely on the active I/O module mounted to it (e.g., CC-PAIX01).
• Conformal Coating (G3 Standard): The “51” suffix designates factory conformal coating to meet ISA-S71.04 Class G3 harsh environment standards. For standard non-corrosive control room environments, the non-coated variant (CC-TAIX01 or CC-TAID01) can be used.
• Redundancy Options: The CC- is a single, non-redundant base plate. If dual-module fault tolerance is required in harsh environments, choose the conformal-coated redundant variant (CC-TAIX61 or CC-TAID61).
• Physical Keying: Designed exclusively for differential/high-level analog input cards. Physical keys prevent accidental mounting of output or digital modules.

Frequently Asked Questions (FAQ)

Q: What does the conformal coating on the CC- do?

A: Conformal coating is a protective polymeric layer applied over the circuit board surface. It isolates components from moisture, airborne salts, sulfur dust, and reactive chemicals, preventing corrosion and current leakage in harsh industrial environments (ISA Class G3).

Q: This base is listed as New Surplus. How can I be sure it is not used or refurbished?

A: This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability. Our inventory comes directly from surplus project stocks, canceled expansion projects, and factory spare holds. Each unit features pristine terminal contacts, intact coating layers, factory labels, and zero field operation hours.

Q: How does your pricing compare to buying factory-direct from Honeywell or an online broker?

A: Our pricing reflects the cost of securing genuine New Surplus inventory globally. It may be 20–30% higher than a refurbished gamble, but it is substantially less than OEM list prices, and it buys you 100% peace of mind. You avoid extended factory lead times while eliminating the risks of corroded traces, stripped terminals, and contact failure associated with pre-owned parts.

Q: What is the main difference between CC- and CC-TAID01?

A: Both are 16-channel non-redundant Analog Input IOTA bases with identical pinouts and mounting dimensions. The distinction is environmental protection: CC- has G3 conformal coating for harsh environments, while CC-TAID01 is a standard non-coated base for clean control rooms.

Q: What warranty and quality verification process do you offer with this module?

A: Every CC- unit includes a full 1-Year functional replacement warranty. Before shipment, each assembly undergoes visual coating checks, terminal torque inspections, ground continuity verification, and pin insulation testing to guarantee plug-and-play field readiness.
