Overview

The Honeywell 8C-PDIS01 is a high‑performance digital input module designed for Experion PKS Series 8 systems. It captures discrete signals from field devices with high accuracy and provides advanced Sequence of Events (SOE) recording. Moreover, the module offers millisecond time stamping, enabling operators to reconstruct event sequences during plant upsets or shutdowns.

In addition, its rugged design ensures reliable operation in harsh industrial environments, while built‑in diagnostics simplify maintenance and reduce downtime. For instance, engineers can quickly identify wiring issues through open‑wire detection, improving overall system reliability and safety.

Technical Data

Typical Applications

The 8C-PDIS01 is widely used in industries where precise event tracking is essential. Moreover, it supports safety systems by recording the exact order of digital input changes during trips or shutdowns.

In addition, it is deployed in process monitoring to capture signals from sensors, switches, and relays with millisecond accuracy. For instance, power generation plants rely on SOE functionality to analyze disturbances, improve root‑cause analysis, and enhance operational resilience. Therefore, this module is an excellent choice for facilities requiring reliable digital input acquisition and advanced diagnostics.

FAQ
