Product Description

The 8C-PAIH54 (P/N: 51307070-275) is a versatile, high-density analog input acquisition module designed for the Honeywell Experion PKS Series 8 architecture. It provides 16 single-ended input channels, converting raw field signals into high-resolution digital data for use within the C300 control environment.

Unlike fixed-signal analog input modules, the 8C-PAIH54 supports a wide variety of signal types, including current, voltage, and direct temperature sensor inputs. Its rugged industrial design ensures stable and accurate signal processing even in extreme operating conditions, maintaining data integrity from the field level to the control room.

Application Scenarios

The 8C-PAIH54 is commonly used in refining, chemical, and pharmaceutical facilities where multiple sensor technologies coexist, such as:

  • Pressure and flow transmitters

  • RTDs and thermocouples

By supporting mixed signal types on a single module, it reduces hardware variety, simplifies engineering, and optimizes control cabinet space.


Frequently Asked Questions

Q: Does the 8C-PAIH54 require external signal conditioning for thermocouples?
A: No. The module directly accepts thermocouple and RTD inputs, performing internal linearization and cold-junction compensation.

Q: Is the 8C-PAIH54 compatible with C200 controllers?
A: No. This module is designed for the Series 8 platform, typically paired with C300 controllers. C200 systems require a different I/O family, such as Chassis I/O.
