Description
Product Introduction & Engineering Value
The CC-TAIN01 is not an analog-input IOM itself. It is the Interface Termination Assembly (IOTA) that provides the physical field-termination interface for the associated Series C analog-input module. Honeywell specifies it for 16-channel, single-ended analog inputs and identifies it specifically with the CC-PAIN01.
That distinction matters during replacement. A failed IOTA can produce field-signal problems even when the CC-PAIN01 electronics are functioning normally. The correct replacement therefore requires checking both the IOTA model and the installed IOM rather than ordering based only on the words “analog input.”

Honeywell specifies the associated CC-PAIN01 system with a 4–20 mA input through 200 Ω, 16-bit conversion, 50 ms input scanning, and individually protected transmitter field-power circuits.
The Series C user’s guide also confirms that the CC-TAIN01/CC-TAIN11 family is the non-HART analog-input IOTA arrangement and provides the terminal-board wiring information.
Field Application & the “Trench” Experience
A refinery control cabinet developed intermittent transmitter alarms across several channels. The affected transmitters were located in different parts of the unit, so the initial suspicion fell on field wiring.
The maintenance team eventually noticed that the affected signals terminated on the same Series C IOTA. Measurements at the transmitters were normal. Measurements at the cabinet showed inconsistent loop behavior. After isolating the field wiring from the IOTA and checking the termination points, the CC-TAIN01 connection assembly became the common point requiring investigation.
The replacement was followed by individual loop verification at 4 mA, mid-scale, and 20 mA.
The practical lesson is worth remembering: when several unrelated transmitters misbehave on one I/O group, inspect the common termination hardware before replacing the transmitters.
Specific applications include:
- 4–20 mA pressure-transmitter termination in process units
- Temperature-transmitter inputs connected to Experion PKS
- Flow and level measurement loops using conventional current transmitters
- Process analyzer signal acquisition where the instrument presents a standard analog current output
- Distributed process instrumentation connected to Series C non-HART analog-input modules

Transparency SOP: QA & Testing
For New Surplus or Refurbished CC-TAIN01 inventory, inspection should be performed at the termination level:
- Part-number verification — Confirm CC-TAIN01 and the associated 51306513-175 identification where applicable.
- Physical inspection — Examine the PCB, terminal blocks, connectors, mounting points, and board coating.
- Terminal inspection — Check for loose, damaged, oxidized, or heat-affected terminals.
- Continuity testing — Verify the relevant signal paths from field terminals through the IOTA interface.
- Insulation/isolation checks — Perform appropriate electrical checks without exceeding the manufacturer’s limits.
- System test — Install with a compatible CC-PAIN01 in a Series C test environment.
- Loop simulation — Apply known 4–20 mA signals and confirm correct readings through the complete IOTA/IOM path.
- Final documentation — Record part number, revision, condition, test results, and any observed terminal defects.
A visual inspection alone is not enough for an IOTA. The field termination path has to be electrically verified.
The Veteran’s Tech Trap Guide
⚠️ CC-TAIN01 is not the IOM.
This is the most common procurement mistake. CC-TAIN01 is the termination assembly; CC-PAIN01 is the associated analog-input module. Honeywell’s documentation explicitly pairs these components.
⚠️ Do not substitute CC-TAIN11 without checking the architecture.
Honeywell identifies CC-TAIN01 as non-redundant and CC-TAIN11 as redundant. They are not simply two interchangeable versions of the same termination board.
PRO TIP: Photograph the installed IOTA before removal. Record whether the cabinet uses simplex or redundant I/O and identify the exact IOM mounted above or beside the termination assembly.
⚠️ Don’t assume every analog signal is supported by the same IOTA.
The CC-TAIN01 is associated with the non-HART high-level analog-input architecture. Honeywell has separate IOTA families for other Series C input types and HART configurations.
⚠️ The 4–20 mA loop is only one part of the circuit.
If the transmitter has a loop-power problem, do not immediately condemn the IOTA. Check the transmitter, field supply, wiring resistance, terminal connections, and associated CC-PAIN01 channel before replacing the termination assembly.
Dynamic FAQ
Q1. What is the Honeywell CC-TAIN01?
The CC-TAIN01 is a non-redundant analog-input IOTA (Interface Termination Assembly) for Honeywell Experion Series C I/O. It provides the field termination interface for the associated analog-input module.
Q2. Which IOM is used with CC-TAIN01?
Honeywell specifically identifies CC-, the 16-channel high-level analog-input module, with CC-TAIN01.
Q3. How many channels does CC-TAIN01 support?
The associated Series C analog-input configuration provides 16 single-ended channels.
Q4. Is CC-TAIN01 redundant?
No. CC-TAIN01 is the 6-inch non-redundant IOTA. Honeywell specifies CC-TAIN11 for the redundant configuration.
Q5. What signals are used with CC-TAIN01?
The associated CC-PAIN01 accepts 4–20 mA current inputs, including inputs from 2-wire or self-powered transmitters.
Q6. What is the part number associated with CC-TAIN01?
Secondary industrial-part references identify 51306513-175 with CC-TAIN01. For procurement, verify the physical label and revision because Honeywell hardware can have additional identification markings.
Q7. How should New Surplus CC-TAIN01 inventory be authenticated?
Confirm the Honeywell model, part number, physical board configuration, terminal arrangement, and condition. Ideally, test the IOTA with a compatible CC-PAIN01 and known 4–20 mA loop signals.
Warranty: Warranty coverage depends on supplier and stock condition. For refurbished CC-TAIN01 units, request continuity/termination testing and written functional warranty terms before purchase.
