CC-PAIH51 Honeywell Experion Series-C Analog Input HART Module

CC-PAIH51 Honeywell Experion Series-C I/O

The CC-PAIH51 is a high-level analog input module with HART from Honeywell’s Experion Series-C I/O family. It handles 16 single-ended current channels for 2-wire or self-powered transmitters. The module reads 4-20 mA through a 200 Ω resistor. A 16-bit A/D converter delivers precise process data. Field power conditioning includes individually protected current limiting circuits for Class 1, Div 2 non-incendive interfacing. No fusing required.

FAQ

Q: Can the CC-PAIH51 read HART digital signals from my transmitter?

A: Yes. The module supports HART communication. It passes digital data to the Experion controller. You can configure transmitters remotely. Confirm your system firmware supports HART pass-through.

Q: What is the difference between CC-TAIX51 and CC-TAIX61 IOTA boards?

A: CC-TAIX51 is non-redundant and 6 inches wide. CC-TAIX61 is redundant and 12 inches wide. Both accept the CC-PAIH51 module. Choose based on your availability and redundancy needs.

Q: How often should I calibrate the CC-PAIH51?

A: Honeywell recommends annual calibration. The module holds ±0.075% accuracy at 23.5°C. Drift is low. For critical loops, calibrate every six months. Always use a certified current source.

Q: Can I use self-powered transmitters with this module?

A: Yes. The CC-PAIH51 accepts 2-wire and self-powered transmitters. Field power conditioning protects each channel. No external fuses are needed for Class 1, Div 2 areas.

Q: What should I check when buying a used CC-PAIH51?

A: Ask for channel-by-channel test data. Check the IOTA connector pins for corrosion. Verify HART communication works. Oiltech Controls tests each unit and provides a 12-month warranty.
