Open Wire Diagnostics
Features:
- Thirty-two 24 V DC discrete inputs with 1 ms sequence-of-events resolution.
- Normal and SOE modes: 20 ms PV scan; Low Latency mode: 5 ms PV scan.
- Optical isolation and optional redundancy; open-wire detection in Normal mode only.
Honeywell specifies CC-PDIS01 for discrete field-signal acquisition and sequence-of-events recording in Series C I/O. Its thirty-two inputs accept nominal 24 V DC signals within a documented DI power range of 18-30 V DC. Event time-tagging provides 1 ms resolution, while the PV scan follows the selected operating mode. The optical isolation rating is 1500 V AC RMS or ±1500 V DC with an input terminal referenced to common. These values describe different electrical and timing characteristics and must not be combined into an unsupported claim of 1 ms end-to-end response.
Configuration determines the available diagnostic behavior. Normal mode supports open-wire detection and marks the affected PV invalid when that fault is diagnosed. SOE mode retains a 20 ms PV scan, while Low Latency mode uses 5 ms; open-wire detection is not listed for those modes. Select the approved IOTA, field-power arrangement, signal polarity and any redundant pairing before commissioning. Retain the complete CC-PDIS01 51405042-175 marking in the replacement record. The reviewed original pages do not define the numeric suffix or prove interchangeability with other part-number revisions.
The CC-PDIS01 51405042-175 Honeywell Digital Input Sequence of Events Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
Honeywell CC-PDIS01 51405042-175 official technical documentation and product links.
This multi-page Honeywell technical document contains the exact model and its technical data. Apply the values to the supplied type number and verify its revision before installation.
Choose Normal, Sequence of Events or Low Latency operation according to the control strategy. Normal and SOE modes scan the PV every 20 ms; Low Latency uses 5 ms. The 1 ms figure is event resolution, not the PV scan or a guaranteed whole-system response. Verify configured event recording and time order during commissioning.
Use a field-power source within 18-30 V DC. The documented ON threshold is at least 13 V DC or 3 mA; the OFF threshold is at most 5 V DC or 1.2 mA. Input impedance is 4.2 kilohms. Check contact leakage, cable resistance and source capability against these limits rather than assuming any nominal 24 V device is suitable.
Open-wire detection is documented for Normal mode only. A diagnosed open field wire is annunciated and causes the associated PV to be marked invalid. Confirm mode selection and the installed wiring arrangement before testing this function. Do not promise the same diagnostic in SOE or Low Latency mode, and follow the approved maintenance procedure for any fault simulation.
