CC-PAIH01 Honeywell Analog Input Module with HART 16-Channel

CC-PAIH01 Honeywell High-Level Analog Input with HART

The CC-PAIH01 is a Honeywell high-level analog input module with HART support. It reads current or voltage signals from transmitters and sensing devices. It fits process control cabinets that need fast loop scan and strong diagnostics. The module pairs with CC-TAIX, CC-GAIX, and CC-TAID IOTA models for non-redundant or redundant layouts. Related model: CC-PAIH02 high-level analog input with HART.

Function and Signal Path

• Accepts high-level current or voltage inputs.
• Supports 2-wire and self-powered transmitters.
• Handles 0 to 5 V, 1 to 5 V, 0.4 to 2 V, and 4-20 mA via 250 Ω.
• Uses a 16-bit A/D converter.
• Scans inputs every 50 ms for fast loop updates.

Channel Layout and Accuracy

• 16 channels: 12 single-ended plus 4 differential.
• Hardware accuracy ±0.075% of full scale at 23.5°C ±2°C.
• Hardware accuracy ±0.15% of full scale from 0 to 60°C.
• Voltage input impedance above 10 MΩ when powered.
• Maximum normal mode input ±30 V on differential inputs, no damage.

Noise, Rejection, and Filtering

• Common mode rejection: 70 dB from dc to 60 Hz at 500 Ω source imbalance.
• Common mode voltage: -6 to +5 V peak, dc to 60 Hz.
• Normal mode rejection: 19 dB at 60 Hz.
• Single-pole RC filter, -3 dB at 6.5 Hz.
• Channel-to-channel crosstalk: -60 dB from dc to 60 Hz.

Diagnostics and Field Power

• Extensive self-diagnostics for loop health checks.
• Open wire detection flags bad PV conditions.
• Optional redundancy for critical loops.
• Supplies non-incendive field power for Class 1, Div 2 areas.
• Individually protected current limiting circuits, no fusing required.
• HART-capable for multivariable instruments and multiple modems.

Compatible IOTA Models

• CC-TAIX01 non-redundant and CC-TAIX11 redundant.
• CC-GAIX21 non-redundant and CC-GAIX11 redundant.
• CC-TAID01 non-redundant and CC-TAID11 redundant.
• Check backplane and firmware level before ordering.

Ideal Equipment and System Fit

Technical FAQ

Q: Can this module read both current and voltage inputs?

A: Yes. It reads 0 to 5 V, 1 to 5 V, 0.4 to 2 V, and 4-20 mA through 250 Ω.

Q: What does open wire detection do for my loop?

A: It flags a bad PV when the field wire opens. This helps you spot broken transmitter loops fast.

Q: How fast is the input scan?

A: The module scans inputs every 50 ms. That suits fast control loops in process cabinets.

Q: Which IOTA should I pick for redundancy?

A: Use the redundant IOTA variants, such as CC-TAIX11 or CC-GAIX11. Match the rack slot first.

Q: How do I confirm compatibility before ordering?

A: Send the rack type, IOTA model, and system firmware version. We check the fit before shipment.
