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.

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.
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.
Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
Finding brand new, original modules is critical for our safety. This team delivers factory-fresh components with full certification. Their commitment to only selling new products makes them our most trusted partner.
We have sourced Honeywell and Schneider parts here for two years. Every shipment arrives well-packaged with original factory seals intact. Clear communication and the best lead times in the industry.
