Honeywell CC-PDIL51 / CC-TDIL51 — 24VDC Digital Input Module | Experion PKS C300 DCS Platform
Engineering Background
The CC-PDIL51 (process module) and CC-TDIL51 (terminal assembly) form a matched pair within Honeywell’s Experion PKS Series C architecture. Designed for mission-critical process industries — refining, petrochemical, power generation, and pulp & paper — this module pair delivers deterministic 24 VDC digital input acquisition with channel-level isolation and full integration into the C300 Controller ecosystem.
Product Positioning
As a native Experion PKS I/O component, the CC-PDIL51/CC-TDIL51 eliminates the integration overhead of third-party I/O. Procurement engineers sourcing replacement or expansion modules for existing C300 cabinets will find this unit a direct, firmware-compatible drop-in with no re-engineering required.

- Long Service Life: Honeywell’s extended product lifecycle commitment supports 10+ year operational horizons
System Architecture & Signal Flow
Field devices (limit switches, proximity sensors, relay contacts) wire directly to the CC-TDIL51 terminal assembly via screw terminals. The terminal assembly mates with the CC-PDIL51 process module, which conditions and digitizes the 24 VDC signals. Conditioned data is transmitted over the C300 FTE backplane to the C300 Controller, where it is processed by control strategies built in Honeywell’s Control Builder engineering environment. Alarm and diagnostic data propagates to Experion Station operator consoles in real time.

Technical FAQ
Q: Can the CC-PDIL51 be used without the CC-TDIL51 terminal assembly?
A: No. The CC-PDIL51 process module requires the CC-TDIL51 terminal assembly for field wiring. They must be ordered and installed as a matched pair.
Q: Is this module compatible with Experion PKS R400 and later releases?
A: Yes. The CC-PDIL51/CC-TDIL51 is forward-compatible with Experion PKS R400+ subject to standard firmware upgrade procedures documented in Honeywell’s release notes.
Q: Can I mix CC-PDIL51 with other C300 I/O modules in the same chassis?
A: Yes. The C300 I/O chassis supports mixed module types. Slot assignment is configured in Control Builder with no hardware restrictions between DI, DO, AI, and AO module types.
Q: What is the maximum cable length for field wiring to the CC-TDIL51?
A: Honeywell recommends a maximum of 300 m for 24 VDC DI circuits using 1.5 mm² shielded twisted-pair cable. Longer runs require voltage drop calculations and may need signal repeaters.
Q: Do you provide a Certificate of Conformance (CoC)?
A: Yes. A CoC is included with every shipment. Factory test reports are available upon request for critical applications.
