Honeywell CC-PDIS01 Digital Input Sequence of Events

Overview

The Honeywell CC-PDIS01 (part number 51405042-175/176) is a 32-Channel Digital Input Sequence of Events (DISOE) Module for Honeywell Experion™ PKS Series C distributed control systems. It captures discrete input state changes with 1 ms timestamp resolution, enabling precise event sequencing for safety diagnostics and root-cause analysis.

FAQ

Q: What is the SOE resolution?
A> The CC-PDIS01 provides 1 millisecond timestamp resolution for Sequence of Events applications.

Q: What IOTA bases are compatible?
A> Compatible IOTAs include CC-TDIL01 (non-redundant, 9"), CC-TCML11 (redundant, 12"), CC-GDIL11 (redundant, 12"), CC-GDIL21 (non-redundant, 6").

Q: Can I use this for standard digital input without SOE?
A> Yes, the Normal mode (20 ms scan) operates as a standard 32-channel DI module without SOE timestamping.

Installation Guidelines

1. Mount the CC-PDIS01 on the appropriate IOTA base (CC-TDIL01, CC-TCML11, etc.).
2. Configure internal or external field power via jumper settings.
3. Connect 24 VDC discrete field wiring to the terminal blocks.
4. Configure SOE mode via Experion PKS Control Builder if timestamping is required.
5. Verify input status and SOE timestamps via Experion PKS diagnostics.

Selection Tips

• Choose CC-PDIS01 when you need 1 ms SOE resolution for trip diagnostics or event sequencing.
• For standard digital input without SOE, a standard DI module may be more cost-effective.
• Verify IOTA base model matches your redundancy and space requirements.
