Description
Product Overview
The Honeywell CC-TDIL01 is a 24 VDC digital-input IOTA used within the Experion PKS Series-C I/O architecture. The IOTA is the field-termination and interface assembly rather than the processor itself. Honeywell documentation specifically identifies CC-TDIL01 as the non-redundant 9-inch IOTA for Series-C 24 V digital-input applications, while CC-TDIL11 provides the corresponding redundant 12-inch arrangement.
In the Series-C architecture, Honeywell CC-TDIL01 interfaces field discrete signals with the associated digital-input I/O electronics. Honeywell’s documentation specifies a 32-channel input architecture for the Sequence-of-Events implementation, with a normal process-value scan of 20 ms, a fast scan of 5 ms, and 1 ms SOE resolution. The documented input range is 18–30 VDC, with an ON threshold of at least 13 VDC or 3 mA and an OFF threshold of no more than 5 VDC or 1.2 mA. Optical isolation in the I/O module provides up to 1500 VAC RMS or ±1500 VDC isolation relative to common.
A critical procurement point: CC-TDIL01 is an IOTA, not a standalone 32-channel CPU or generic digital-input card. Honeywell documentation lists it with specific Series-C input modules, including CC-PDIS01 for Sequence-of-Events applications. The actual field wiring, redundancy requirement, terminal assembly, and associated I/O module must therefore be checked before ordering. Treating CC-TDIL01 as interchangeable with similarly named Series-C IOTAs can create an expensive cabinet-level mismatch.
Product Introduction
When a Series-C digital-input channel has a field-termination problem, replacing the IOTA can be more appropriate than replacing the entire I/O assembly. Honeywell CC-TDIL01 provides the 24 VDC field interface for Series-C digital-input applications and supports a 32-channel architecture.
For an Experion PKS DCS replacement, check the associated I/O module, redundancy arrangement, terminal wiring, and IOTA part number together. CC- and CC-TDIL11 are not simply interchangeable physical variants.

Frequently Asked Questions
What is Honeywell CC- used for?
CC- is a Series-C 24 VDC digital-input IOTA. It provides the field termination/interface arrangement for discrete input applications in Honeywell’s Experion PKS Series-C architecture. Honeywell identifies it specifically as the non-redundant 9-inch IOTA.
It should not be confused with the processor or the actual digital-input processing module.
How many digital inputs does CC- support?
The documented Series-C DISOE configuration specifies 32 input channels.
Be careful with catalog listings that state 24, 8, or other channel counts for this model. Public secondary listings contain conflicting specifications. For engineering purposes, the Honeywell Series-C documentation is the better reference.
Does CC- support 1 ms Sequence of Events?
Yes, when used with the appropriate Sequence-of-Events input module/configuration.
Honeywell specifies CC- with CC- as a supported IOTA combination and specifies 1 ms digital-input resolution for SOE. Normal PV scanning is 20 ms, while fast PV scanning is 5 ms.
That distinction matters: 1 ms SOE resolution does not mean that every ordinary digital-input application automatically operates with a 1 ms process-value scan.
Can I hot-swap the CC-?
Do not assume it is hot-swappable.
CC- is part of the field termination and I/O signal path. Live replacement depends on the specific Series-C installation, I/O redundancy, cabinet design, and approved maintenance procedure.
Before removing the IOTA, confirm the plant’s online-maintenance procedure and determine whether the associated I/O module is redundant.
Is CC- interchangeable with CC-TDIL11?
No—not as a blanket replacement.
Honeywell identifies CC- as a non-redundant 9-inch IOTA and CC-TDIL11 as a redundant 12-inch IOTA.
The correct choice depends on the installed I/O architecture. Physical fit, wiring, redundancy, and associated module configuration all need to agree.
Will replacing CC- erase my Experion control logic?
The IOTA is not the location of the main Experion control strategy. Replacing the field-termination assembly therefore should not be treated like replacing a controller CPU.
The important recovery work is different:
- Record all field wiring.
- Verify terminal assignments.
- Confirm the associated I/O module.
- Check the redundant/non-redundant configuration.
- Validate each affected input after replacement.
- Confirm alarm and interlock states before returning the loop to service.
A wiring error can be more consequential than a configuration error on a digital-input termination assembly.
How should I verify a New Surplus CC-?
For this part, inspect the IOTA assembly and its associated hardware, not only the outer label.
Check:
- model marking
- 51308386-175 part number where applicable
- PCB revision
- Terminal blocks and connectors
- Jumper configuration
- Field wiring condition
- Evidence of corrosion or overheating
- Associated I/O module compatibility
- 24 VDC input-path test
- Channel continuity and isolation
- Condition of the terminal plug-in assembly
To be completely transparent, online listings frequently mix CC- specifications with other Series-C digital-input modules. Honeywell’s own documentation clearly identifies CC- as the 24 V digital-input IOTA, so procurement should be based on the exact IOTA/module combination rather than a generic “digital input module” description.
