Product Description

The 8C-PDISA1 is a high-performance Digital Input (DI) module with Sequence of Events (SOE) capability for the Honeywell Experion PKS Series 8 / C300 platform. It is specifically designed to capture discrete signal state changes with millisecond precision, providing an accurate chronological log for root-cause analysis following process trips or equipment failures.

Factory-applied conformal coating (CC, G3 rating) ensures reliable operation in corrosive, humid, or harsh environments. The module provides 32 optically isolated channels and integrates seamlessly with C300 controller architectures, offering advanced noise filtering and signal debouncing to record only valid transitions.

Application Scenarios

The 8C-PDISA1 is widely deployed in safety-critical industrial sectors, including:

Power plant protection systems
Oil & gas emergency shutdown (ESD) loops
High-speed manufacturing lines

Its millisecond-level timestamping allows operators to identify first-out alarms versus subsequent ripple-effect trips, enhancing plant safety, troubleshooting accuracy, and uptime.

Frequently Asked Questions

Q: What is the primary benefit of the 8C-PDISA1 over a standard DI module?
A: The 8C-PDISA1 timestamps digital inputs at the source with 1 ms resolution, while standard modules are limited by the controller scan cycle.

Q: Is the 8C-PDISA1 compatible with non-conformal coated systems?
A: Yes. It can be installed on standard Series 8 IOTAs. Using a conformal-coated module in a standard environment provides extra protection, but using a non-coated module in a harsh environment is not recommended.
