Product Description

The 8C-PAIH51*E is a robust industrial analog input module engineered for the Honeywell Experion PKS Series 8 platform. It provides accurate 4–20 mA signal acquisition, forming a reliable interface between field instrumentation and the control layer.

Designed for operation in extreme environmental conditions, the module maintains high signal integrity and diagnostic transparency for critical process variables. High-performance analog-to-digital conversion ensures low-latency data processing, while seamless integration with the C300 controller environment supports deterministic, high-speed communication.
