The CC-PDIS01 is a high-density digital input module engineered for Sequence of Events (SOE) monitoring within the Honeywell Experion PKS architecture. It provides 32 independent input channels capable of capturing rapid state changes with millisecond-level precision. By offloading event timing from the C300 controller, the module ensures highly accurate event sequencing for process trips and advanced diagnostics.
Designed for maximum reliability, the CC-PDIS01 incorporates optical isolation to protect control systems from electrical surges on the field side. Its seamless integration with dedicated I/O Termination Assemblies (IOTA) simplifies wiring while supporting high-availability configurations in demanding industrial environments.

The CC-PDIS01 is widely applied in critical industrial systems such as power plant turbine control, emergency shutdown systems (ESD), and high-speed manufacturing lines. It is particularly valuable in applications requiring precise event sequencing, enabling accurate root-cause analysis by capturing the exact order of digital signal changes.
What makes this module different from a standard digital input?
Unlike standard digital input modules, the CC-PDIS01 features dedicated onboard SOE processing. It timestamps signal transitions directly at the module level with 1 ms resolution, independent of the controller scan cycle.
Is the module powered independently?
No. The CC-PDIS01 receives its logic power through the IOTA backplane connection, simplifying power distribution and reducing overall wiring complexity.
