Product Description

The 8C-PAIHA1 (P/N: 51454470-275) is a high-integrity HART-enabled analog input module engineered for the Honeywell Experion PKS Series 8 platform. It provides reliable signal acquisition for 16 analog input channels, acting as the interface between precision field instruments and the C300 controller.

Supporting HART protocol pass-through, the module enables access to secondary variables and diagnostic data from smart transmitters, allowing enhanced asset management without additional wiring. Its high-density Series 8 form factor minimizes cabinet space requirements while maintaining strong galvanic isolation and noise immunity, making it suitable for continuous operation in demanding process environments.

Application Context

The 8C-PAIHA1 is commonly used in safety-critical and high-uptime operations, including:

Petrochemical and refinery facilities
Offshore oil & gas platforms
Large-scale power generation plants

HART integration enables remote device diagnostics, calibration checks, and health monitoring, reducing maintenance effort and unplanned downtime.

Frequently Asked Questions

Q: Does the 8C-PAIHA1 support redundancy?
A: Yes. When used with the appropriate redundant termination assembly, the module can be installed in a redundant configuration to maintain operation during a hardware failure.

Q: What is the main advantage of HART functionality?
A: HART allows access to device-specific diagnostics and secondary variables—such as internal sensor status and temperature—that are not available through a standard 4–20 mA signal alone.
