Honeywell CC-TDIL01 32-Channel 24VDC DI IOTA

Description

Key Technical Specifications

Honeywell’s Series C documentation identifies CC-TDIL01 as the 9-inch non-redundant IOTA for the 32-channel CC-PDIL01 digital input module. The same IOTA is also used with the CC-PDIS01 SOE module.

Product Introduction

The Honeywell CC-TDIL01 is a 9-inch non-redundant I/O termination assembly for Series C 24 VDC digital input applications. It interfaces with the 32-channel CC-PDIL01 or CC-PDIS01 module and supports field input voltages from 18 to 30 VDC. The associated I/O architecture provides optical galvanic isolation and open-wire diagnostics for applicable configurations.

Installation & Configuration Guide

Stage 1 — Pre-Installation

1. Confirm that the installed I/O module is CC-PDIL01 or CC-PDIS01.
2. Verify that the cabinet requires a 9-inch non-redundant IOTA.
3. Confirm the field signal architecture and 24 VDC input range.
4. Record all 32 channel assignments, field device tags, polarity, and terminal wiring.
5. Back up the applicable Experion PKS I/O configuration.
6. Photograph the existing termination arrangement before disconnecting conductors.
7. Check the replacement IOTA for model marking, revision, connector condition, corrosion, or evidence of rework.
8. ⚠️ Safety: Place affected loops and equipment in the approved maintenance state before removing the IOTA.
9. Use a grounded ESD wrist strap and suitable ESD work surface when handling the Series C assembly.

Typical preparation time: 15–30 minutes for a well-documented cabinet.

Stage 2 — Removing Old Module

1. Isolate applicable control and field power according to the site maintenance procedure.
2. Verify the absence of hazardous voltage before touching field terminals.
3. Label each conductor with its channel number and field-device reference.
4. Photograph the wiring from multiple angles for traceability.
5. Disconnect field wiring carefully, avoiding disturbance to adjacent I/O.
6. Remove the associated CC-PDIL01 or CC-PDIS01 module according to the Series C procedure.
7. Release the IOTA mounting hardware.
8. Remove the CC-TDIL01 and place it in ESD-safe packaging.
9. Inspect the cabinet connector and surrounding wiring before installation.

⚠️ Critical: Do not select CC-TDIL01 merely because it physically fits a Series C cabinet. Honeywell’s compatibility matrix associates specific I/O modules with specific IOTA families.

Stage 3 — Installing New Module

1. Inspect the replacement CC-TDIL01 for physical damage and contamination.
2. Verify the model marking before mounting.
3. Position the 9-inch IOTA in the designated Series C cabinet location.
4. Secure the assembly according to the applicable Honeywell installation procedure.
5. Install the compatible CC-PDIL01 or CC-PDIS01 module.
6. Reconnect field wiring channel by channel against the recorded documentation.
7. Verify DC polarity and signal identification for every input.
8. Confirm that field wiring resistance is appropriate for the intended ON/OFF thresholds.
9. Recheck all 32 terminations before restoring power.
10. Do not substitute the redundant CC-TDIL11 without verifying the cabinet architecture and available mounting space.

Honeywell specifies CC- as the non-redundant 9-inch IOTA and CC-TDIL11 as the redundant 12-inch counterpart.

Typical replacement time: 30–60 minutes, depending on wiring density and documentation quality.

Stage 4 — Power-On & Testing

1. Complete a final visual inspection of all field terminations.
2. Restore power using the approved startup sequence.
3. Verify that the I/O module initializes without diagnostic faults.
4. Confirm that all configured digital input channels are available in Experion.
5. Apply representative 24 VDC input signals or use an approved simulation/test source.
6. Verify ON-state detection against the specified 13 VDC/3 mA minimum threshold.
7. Verify OFF-state detection against the specified 5 VDC/1.2 mA maximum threshold.
8. Check open-wire and channel diagnostic indications where applicable.
9. Confirm the correct state transition at the controller/operator interface.
10. Compare the restored input states with the pre-maintenance record.
11. Return affected loops to normal service only after operator and control-engineering approval.
12. Record model, revision, traceability information, test results, and removed-part disposition.

⚠️ Field warning: A frequent commissioning mistake is checking only whether a 24 VDC input changes state. The wiring resistance and actual threshold behavior also matter. Honeywell specifies both voltage/current thresholds and guaranteed field-resistance limits for the CC- architecture.

Frequently Asked Questions (FAQ)

Q1: What is the Honeywell CC-?
CC- is a 9-inch non-redundant IOTA used with Honeywell Series C 24 VDC digital input modules.

Q2: Which I/O modules use CC-?
Honeywell documentation identifies CC- and CC- as compatible I/O modules. CC- provides 32-channel 24 VDC digital input, while CC- provides the applicable SOE digital-input function.

Q3: How many channels does the CC- support?
The associated CC- architecture provides 32 digital input channels.

Q4: What is the difference between CC- and CC-TDIL11?
CC- is the 9-inch non-redundant IOTA. CC-TDIL11 is the 12-inch redundant IOTA for the same Series C digital-input family.

Q5: What voltage does the associated CC- accept?
The CC- specifies an 18–30 VDC DI power/input range. Its minimum ON sensing threshold is 13 VDC or 3 mA, while the maximum OFF sensing threshold is 5 VDC or 1.2 mA.

Q6: Does CC- provide electrical isolation?
The associated CC- architecture specifies optical isolation in the I/O module and 1,500 VAC RMS or ±1,500 VDC isolation referenced to common.

Q7: Can CC- be replaced directly with another Series C IOTA?
Not automatically. CC- belongs to the 24 VDC digital-input IOTA family. Verify the I/O module model, redundancy requirement, cabinet size, field wiring, and Honeywell compatibility matrix before selecting a substitute.
