CC-PDIL01 Honeywell 24VDC Digital Input Module – 32-Channel Series C I/O
CC-PDIL01 is a Honeywell Series C 24VDC Digital Input module with 32 channels. It reads 24VDC discrete signals from field devices. The module offers extensive internal diagnostics, open-wire detection, and optional redundancy. It suits continuous process control and safety-related monitoring. Galvanic isolation protects the IOM from field transients. On-board excitation power removes the need for marshalling power. The module also supplies non-incendive field power. Users can select internal or external field power. Direct or reverse input indication helps commissioning.

Diagnostics Capability
The module performs extensive internal diagnostics for data integrity. It detects and annunciates open field wire conditions. A channel with open-wire diagnosis reports its PV as invalid. This blocks incorrect control action. Optional redundancy adds another layer of availability.
Installation Guide
Mount the IOTA on the Series C rail. Seat the CC-PDIL01 IOM firmly. Select internal or external field power before wiring. Use shielded twisted pairs for field inputs. Keep input wiring away from high-voltage cables. Verify ON and OFF thresholds after wiring. Check open-wire flags during loop checkout.
Commissioning and Maintenance
Use direct or reverse input indication to match field logic. The on-board excitation power simplifies loop checkout. No marshalling power is needed. Read channel diagnostics from the control system. Replace a faulty module only after technical verification. Redundant IOTA options allow online service in many cases.
Typical Applications
- Discrete valve position feedback
- Pump and motor run status
- Limit switch and proximity sensor inputs
- Alarm and trip contact monitoring
- Safety-related discrete monitoring with open-wire detection
Certifications and Compliance
The module supports non-incendive field power supply. Galvanic isolation meets 1500 VAC RMS or ±1500 VDC. Refer to the Honeywell Series C documentation for the full certification list for your IOTA and cabinet configuration.
