Features:
- Honeywell section 5.12 identifies 32 channels of 24 VDC digital input.
- The cited table gives 18-30 VDC DI power, optical isolation and 5 ms ±20% delay.
- Honeywell lists open-wire detection and CC-TDIL01/11 plus specified GDIL IOTAs.
Honeywell's Release 520 Series-C I/O specification labels CC-PDIL01 Digital Input 24VDC. The module accepts 24 VDC discrete signals on 32 channels. Its table gives an 18-30 VDC DI power range, minimum ON sense of 13 VDC or 3 mA, maximum OFF sense of 5 VDC or 1.2 mA, 4.2 kΩ input impedance and 5 ms ±20% absolute input delay. Galvanic isolation is stated as 1500 VAC RMS or ±1500 VDC relative to common, with optical isolation in the IOM. These are model-level technical limits that must be applied with the listed IOTA and configured field-power arrangement.
Honeywell lists CC-TDIL01 and CC-TDIL11 as standard nonredundant and redundant IOTAs for CC-PDIL01, plus GDIL variants for specified architectures. Its notable features include internal diagnostics, open-wire detection, optional redundancy, selectable internal or external field power and direct/reverse input indication. Before replacement, compare the complete physical CC-PDIL01 label and the additional 51405040-176 number with Honeywell parts records; the PDF does not cross-reference that suffix. Record IOTA type, field excitation, active input states, alarm behavior and controller release. After authorized installation, verify recognition, diagnostics and each affected point under the site commissioning plan. The 2021 specification is not a current lifecycle or hot-swap notice.
The CC-PDIL01 51405040-176 Honeywell 32-Channel 24 VDC Digital Input Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
Honeywell CC-PDIL01 51405040-176 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.
Honeywell names CC-PDIL01 as a 32-channel Digital Input 24VDC module. The OEM source does not map the site's additional 51405040-176 number, so compare the complete physical label and official parts record. Its function must not be confused with CC-PDIS01, the separately listed sequence-of-events input model. The reviewed PDF does not provide present-day support or end-of-life status.
The dedicated OEM table lists 18-30 VDC DI power, 13 VDC or 3 mA minimum ON sense, 5 VDC or 1.2 mA maximum OFF sense, 4.2 kΩ input impedance and 5 ms ±20% absolute delay. Honeywell also describes galvanic and optical isolation. Use these exact-model values with the selected IOTA and field excitation, and verify the configured thresholds before returning points to service.
Honeywell lists CC-TDIL01 nonredundant and CC-TDIL11 redundant IOTAs plus specified GDIL options. It describes open-wire detection, internal diagnostics and selectable internal or external field power. Confirm termination, polarity, point map, redundancy and alarm handling for the installed system. After authorized replacement, check module recognition and prove every affected discrete input; do not infer hot-swap permission from a technical specification.
