Description

The Honeywell CC-PAIH02 is a 16-channel High Level Analog Input module with HART capability designed for the Experion PKS Series C I/O family. Engineered to operate under the control of a Honeywell C300 controller via the high-speed I/O Link network, the module performs signal conditioning, A/D conversion, and input scanning independently of controller processing execution.

The CC-PAIH02 features differential input support across all 16 channels, providing robust noise immunity and accurate signal conditioning for standard 4–20 mA process loops. Equipped with onboard HART modems, the module enables multi-variable digital communication with smart field transmitters without requiring additional marshalling hardware. Dedicated open-wire detection diagnostics safeguard critical process loops by identifying broken field wiring promptly to prevent false process variable (PV) readings.

Features

• 16 Differential Input Channels: Supports differential 4–20 mA analog input signals across all 16 channels for superior noise rejection.
• Integrated HART Communication: Features built-in HART modems to support HART-capable, multi-variable field transmitters and pass-through secondary variables to the control system.
• Fast Loop Scan Rate: Delivers a 50 ms loop scan rate to ensure rapid updating of process variables for continuous control strategies.
• Broken-Wire Detection: Onboard diagnostic monitoring detects open field circuits on 4–20 mA loops and alerts operators via soft failure alarms.
• Non-Incendive Field Power: Delivers non-incendive power directly to field transmitters without requiring external marshalling or safety barriers.
• IOM Redundancy Support: Configurable for optional hardware redundancy on the standard IOTA board to maintain process availability during module maintenance.

Applications

• Continuous Process Monitoring: Interfacing standard 2-wire and self-powered 4–20 mA flow, pressure, level, and temperature transmitters with the C300 controller.
• Smart Field Device Integration: Extracting secondary HART diagnostic variables and multivariable readings directly into Experion PKS control strategies.
• Differential Voltage / Current Measurement: Applications requiring differential analog signal connections to eliminate ground loop interference across field wiring.

Installation Guidelines

1. Pre-Installation Inspection: Verify the part number 51405038-375 on the module label and inspect the edge connector pins for physical damage before mounting.
2. IOTA Carrier Mounting: Ensure the corresponding Series C IOTA (such as CC-TAIX02 or CC-TAIX51/61 series) is securely fastened to the carrier frame and properly grounded.
3. Module Insertion: Align the tilted module guide rails with the IOTA connector slot and press firmly until the locking mechanism fully engages.
4. Field Wiring Check: Verify that field loops (2-wire or self-powered 3/4-wire transmitters) are wired in according to the differential signal polarity indicated in the IOTA pinout diagram.
5. I/O Link Connection: Ensure the redundant I/O Link cables are securely connected to the carrier assembly and assigned a unique address jumper on the IOTA prior to powering on.

Configuration / Commissioning / Replacement

• Control Builder Configuration: Add the AI-HART module block under the appropriate IOLINK block in Control Builder and assign the module address matching the physical IOTA jumpers.
• Channel Parameterization: Set each channel's PV range, engineering units, characterization type (linear, square root), and HART configuration settings.
• Parameter Backup & Switchover: When replacing an existing module, verify that the active C300 controller has backed up the module configuration. Inserting the new module into the active IOTA slot will automatically download the existing parameter set.
• Commissioning Validation: Use the Control Builder Monitoring tab to verify PV readings, check loop current values, and confirm HART communication status for connected field instruments.
