Honeywell 8C-PAIHA1 HART Analog Input Module

Intelligent Analog Measurement with HART Communication for Experion PKS

The Honeywell 8C-PAIHA1 functions as a high-performance HART analog input module within the Experion PKS distributed control system. This module provides 8 universal analog input channels, each supporting 4-20 mA signals with integrated HART digital communication. Its robust housing measures 130 mm in height, 45 mm in width, and 120 mm in depth, fitting standard Series C termination assemblies. The total weight reaches approximately 0.4 kg, combining durability with straightforward installation.

Each channel simultaneously reads the primary process variable and retrieves HART device status information. The following table details the complete technical specifications for this intelligent analog input solution:

HART Communication and Intelligent Device Integration

The 8C-PAIHA1 retrieves secondary HART variables and diagnostic data from field instruments. This capability allows operators to monitor device health, calibration status, and asset management information. The module communicates with the control system through the Series C backplane. Engineers can therefore integrate smart instrumentation seamlessly into the Experion PKS environment.

Analog Measurement Performance and Accuracy

Each channel provides 16-bit resolution with ±0.05% full-scale accuracy. This precision ensures reliable process variable representation. The module maintains its accuracy across the entire operating temperature range. Users benefit from consistent measurement performance in demanding process applications.

System Integration and Configuration Flexibility

The module interfaces directly with the Experion PKS controller for seamless integration. Configuration through the control builder simplifies channel setup and parameter assignment. The module also supports online replacement without system interruption. Process engineers can therefore maintain production while performing hardware maintenance.
