Features:
- Twelve-inch redundant analog-input IOTA form.
- Separate coated and uncoated Honeywell executions.
- Documented pairing with HART and non-HART analog-input IOM families.
The Honeywell Series 8 I/O specification lists 8C-TAIX61 as a coated twelve-inch redundant analog-input IOTA and 8U-TAIX61 as its uncoated counterpart. It pairs the coated IOTA with 8C-PAIN01 non-HART or 8C-PAIH51 HART analog-input electronic modules and identifies parallel uncoated 8U executions. The analog system table documents sixteen single-ended current-input channels and a 4–20 mA range through the associated IOM/IOTA arrangement, but these are system-channel functions rather than evidence that a bare termination assembly performs conversion independently.
The website title combines both coating variants, so a quotation must choose one physical execution rather than implying that one item is simultaneously coated and uncoated. Provide photographs of the supplied label and installed position, the paired IOM, redundancy requirement, cabinet drawings and complete additional markings. The reviewed manufacturer PDF does not map 51306977-175, and that number is retained only as an order-stage verification item. Before installation, label every field conductor and shield. After replacement, verify both redundant paths, channel scaling, HART communication where applicable and controller diagnostics under the approved commissioning plan.
The 8C-TAIX61 8U-TAIX61 51306977-175 Honeywell Series 8 Redundant Analog Input IOTA Executions may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
Honeywell 8C-TAIX61 8U-TAIX61 51306977-175 official technical documentation and product links.
This multi-page Honeywell technical document contains the exact model and its technical data. Apply the values to the supplied type number and verify its revision before installation.
Honeywell defines 8C-TAIX61 as coated and 8U-TAIX61 as uncoated. These are distinct physical executions, not interchangeable names for one undifferentiated item. Match the exact installed label and environmental design requirement before quoting, shipping or installing the replacement.
The redundant IOTAs are documented with Series 8 high-level analog-input electronic modules, including non-HART PAIN01 and HART PAIH51 families in corresponding coated or uncoated executions. Confirm the installed IOM model, redundancy arrangement, channel database and field wiring before moving conductors.
The reviewed Honeywell specification does not associate 51306977-175 with either IOTA execution. The extra number must therefore be checked against the actual product label, traceable order record or another exact manufacturer parts table. It is not presented here as a verified universal identifier for both variants.
