Description
Product Overview
In industrial process control, a digital input is not always just an ON/OFF indication. When a protection relay trips or several interlocks change state within a short interval, the timing and sequence of those events can be essential for identifying the initiating fault. The Honeywell CC-PDIS01 addresses this requirement by accepting 32 discrete 24 VDC input signals and supporting SOE time stamping at 1 ms resolution. It is designed for Honeywell Experion Series-C I/O installations and uses compatible input/output termination assemblies (IOTAs).
The module provides three operating modes: normal operation with a 20 ms process-value scan, SOE operation with 1 ms event-time resolution and a 20 ms process-value scan, and low-latency operation with a 5 ms process-value scan. It also provides optical isolation, internal diagnostics, and selectable internal or external field power. Open-wire detection is available in normal mode; verify the selected operating mode and channel configuration when planning diagnostics.
For replacement work, the Honeywell CC-PDIS01 must be matched to the installed IOTA, controller configuration, and required redundancy arrangement. It is not equivalent to a standard digital input module when millisecond-level event records are required. Before installation, confirm the complete part number, termination assembly, field voltage, and system compatibility. For used or refurbished hardware, request functional-test documentation and verify the event-recording function rather than relying only on a basic input-state test.
Product Introduction
When several protection and interlock signals change close together, a standard process-value scan may not provide the event timing needed for a clear fault investigation. The CC-PDIS01 adds 1 ms SOE time-stamping resolution to 32-channel, 24 VDC discrete input acquisition in compatible Experion installations.
Correct configuration remains important: SOE resolution is not the same as total field-to-controller response time. Check the IOTA, scan mode, signal wiring, and controller configuration before commissioning.

Frequently Asked Questions
1. Can I hot-swap the Honeywell CC-?
Do not assume live removal is permitted in every installation. Follow the applicable Honeywell hardware instructions and site maintenance procedure. Confirm the IOTA type, redundancy arrangement, and impact on event monitoring before removing the module.
2. Does the CC- support firmware v3.1?
A standalone firmware v3.1 requirement is not established for this I/O module. Verify the controller, Experion software release, I/O module revision, and system compatibility requirements together.
3. What does 1 ms SOE resolution mean?
It means the module supports event time stamping at 1 ms resolution. It does not guarantee that the complete field-to-controller signal path responds within 1 ms. Input filtering, isolation delay, scan mode, and controller processing also affect system behavior.
4. Can the CC- replace a CC-PDIL01?
Not as a direct substitution without engineering review. Both support 32-channel, 24 VDC digital input service, but the CC- adds SOE functionality. Confirm the IOTA, controller configuration, and application requirements before changing module type.
5. Does the CC- detect open field wires?
Honeywell’s Series-C documentation specifies open-wire detection in normal mode. Check the selected mode and wiring arrangement before relying on this diagnostic during commissioning or fault investigation.
6. Which termination assemblies are compatible with the CC-?
The documented IOTA options include CC-TDIL01, CC-TDIL11, CC-GDIL11, CC-GDIL21, CC-GDIL01, and CC-SDXX01 for specified installation arrangements. Select the exact IOTA according to the cabinet layout, redundancy design, and applicable hardware documentation.
7. What should I check when purchasing a replacement CC-?
Confirm the complete model and part number, module revision, compatible IOTA, field-voltage range, SOE operation, physical condition, test documentation, warranty, and return terms. If SOE is essential to the application, request evidence that event capture and time-stamping functions were included in the test procedure.
