The 8C-PAINA1 is a high-density analog input module developed for the Honeywell Experion PKS Series 8 I/O platform. It utilizes a single-ended input configuration, enabling efficient channel density within the C300 controller environment while maintaining accurate signal acquisition from field devices.
This module converts continuous analog signals—such as 4–20 mA or 1–5 V—from transmitters into high-resolution digital data for real-time monitoring and control. Designed for high-availability applications, the 8C-PAINA1 integrates seamlessly with I/O Termination Assemblies (IOTA) and includes advanced diagnostics for detecting open circuits and abnormal signal conditions, ensuring reliable operation in mission-critical systems.

The 8C-PAINA1 is widely used in:
Power generation plants
Chemical processing facilities
Water treatment systems
Typical applications include:
Monitoring pressure, flow, and temperature transmitters
High-density analog signal acquisition
Centralized control room installations with shared ground systems
Its single-ended design makes it particularly suitable for cost-effective, high-channel-count deployments where isolation is not required.
Can the 8C-PAINA1 be replaced while the system is live?
Yes. The module supports RIUP (Removal and Insertion Under Power) when used with compatible Series 8 IOTA assemblies, allowing maintenance without interrupting system operation.
What is the advantage of the single-ended design?
Single-ended inputs allow higher channel density within a smaller footprint, making the 8C-PAINA1 ideal for applications where cabinet space is limited and multiple signals share a common ground reference.
