HONEYWELL CC-PDIS01 (51405042-175) – 24 VDC Digital Input Module | Experion PKS C300 DCS Platform
Engineering Background
The CC-PDIS01 is a field-proven Digital Input (DI) module designed for Honeywell’s Experion PKS (Process Knowledge System) platform, operating within the C300 Controller Series. It serves as the primary interface between field-level discrete sensors—limit switches, proximity detectors, relay contacts, and pushbuttons—and the Experion control network. Engineered to IEC 61131-2 input standards, this module delivers deterministic signal acquisition with hardware-level isolation, making it a cornerstone component in safety-critical and continuous-process environments.
Product Positioning
Targeted at procurement engineers and MRO specialists managing Honeywell DCS infrastructure, the CC-PDIS01 is the standard replacement and expansion module for C300-based control cabinets. Whether you are executing a planned maintenance swap, recovering from an unplanned failure, or expanding I/O capacity for a process modification, this module provides a direct, firmware-compatible drop-in solution without requiring controller reconfiguration.

Engineering Advantages
- Direct C300 Backplane Compatibility: Plug-and-play replacement with no firmware flashing required when replacing a like-for-like module in an existing C300 chassis.
- Optical Isolation: Each channel is optically isolated from the backplane bus, preventing ground loops and protecting the controller from field-side transients up to 1500 V (isolation test voltage).
- Open-Wire Diagnostics: Hardware-level open-circuit detection per channel enables proactive fault identification before process impact occurs.
- Hot-Swap Capable: Supports live insertion and removal when used with the appropriate IOTA, minimizing planned downtime during module replacement.
- Deterministic Scan: Synchronized with the C300 controller scan cycle via the FTE backplane, ensuring consistent input latency for interlock and safety logic.
- Wide Thermal Range: Rated to 60°C ambient, suitable for non-air-conditioned marshalling cabinets in tropical and desert plant environments.
System Architecture & Signal Flow
The CC-PDIS01 mounts onto the CC-TDIL01 IOTA (I/O Termination Assembly), which provides the field wiring terminals. Field 24 VDC discrete signals enter through the IOTA terminal blocks, pass through the optical isolation barrier on the CC-PDIS01, and are digitized into on/off state data. This data is transmitted over the C300 backplane FTE bus to the C300 Controller Module (CC-PCF901 or equivalent), where it is processed by the control strategy configured in Experion Control Builder. The module status and channel diagnostics are accessible in real time via the Experion Station HMI and the Experion Asset Manager.
Typical wiring path: Field sensor → IOTA terminal block (CC-TDIL01) → CC-PDIS01 optical isolator → C300 backplane FTE → C300 Controller → Experion PKS Server
Sourcing & Quality Verification
- Stock Origin: Sourced from decommissioned plant upgrades and authorized surplus channels — not grey-market or counterfeit.

- Packaging: ESD-safe anti-static bag, foam-lined carton, humidity indicator card included.
- Documentation: Honeywell original part label, inspection checklist, and certificate of conformance available on request.
- Warranty: 90-day operational warranty against DOA and latent defects.
Procurement Process
- Confirm compatibility: Verify your C300 chassis firmware revision (R310+) and IOTA type (CC-TDIL01) before ordering.
- Request a quote: Contact [email protected] for volume pricing, lead time confirmation, and export documentation (CO, packing list, commercial invoice).
- Place order: Purchase directly via this listing or via PO — we accept T/T bank transfer, PayPal, and trade-term orders (EXW/FOB Xiamen).
- Shipping: DHL Express / FedEx IP standard. Typical transit: 3–7 business days worldwide. Air freight for urgent requirements.
- Incoming inspection: We recommend a bench power-on test and Experion Control Builder module recognition check upon receipt.
Technical FAQ
Q: Is the CC-PDIS01 compatible with the C200 or C200E controller?
A: No. The CC-PDIS01 is designed exclusively for the C300 backplane architecture. C200/C200E systems use a different I/O bus and require CC-PDIS01’s predecessor modules (e.g., MC-PDIS03).
Q: Can this module be used in SIL-rated safety loops?
A: The CC-PDIS01 is a standard (non-SIL) DI module. For SIL 2/3 applications within Experion PKS, Honeywell’s Safety Manager (SM) platform with dedicated SM I/O modules is required.
Q: What is the difference between CC-PDIS01 and CC-PDIS02?
A: The CC-PDIS02 supports 24 VDC isolated (individually referenced) inputs, while the CC-PDIS01 uses a common return (non-isolated between channels). Verify your field wiring configuration before substituting.
Q: Do you provide the IOTA (CC-TDIL01) separately?
A: Yes. Contact us to source the matching IOTA if required. We recommend ordering module and IOTA together to ensure connector compatibility.
Q: Can I get a test report or FAT documentation?
A: A functional inspection checklist is included with every shipment. Full FAT documentation is available for orders of 5+ units upon request.
