Description

The Honeywell CC-PAIX01 (Part Number 51405038-275) is a 16-channel High-Level Analog Input (HLAI) module designed for the Honeywell Experion PKS Series C I/O family. Engineered to interface directly with a Honeywell C300 controller via the dedicated I/O Link network, the module provides high-density signal conditioning and A/D conversion for standard industrial analog current and voltage field transmitters.

Operating under the control of the C300 controller using the AI-HL IOM function block in Control Builder, the CC-PAIX01 processes incoming field signals independently of the main controller execution cycle. The module supports differential input configurations on channels 13 through 16 alongside single-ended high-level inputs, offering signal flexibility and noise suppression for critical process loops.

Designed for demanding process control environments, the 51405038-275 module mounts directly onto Series C Input Output Termination Assemblies (IOTAs). It supports hardware redundancy when installed on compatible redundant IOTA boards, enabling automatic switchover and continuous process monitoring without interruption. Note that the CC-PAIX01 model has been officially succeeded by the CC-PAIX02 model, which expands differential input support across all 16 channels.

Features

• 16 High-Level Channels: Provides 16 input channels designed to accept high-level analog signals from 2-wire and self-powered field transmitters.
• Selectable Differential Inputs: Supports differential input signal connections on channels 13 through 16 for enhanced common-mode noise rejection.
• C300 & I/O Link Integration: Communicates natively with C300 controllers over the I/O Link network via the AI-HL function block in Control Builder.
• Redundancy Support: Fully supports redundant hardware configurations on designated Series C IOTAs to maintain process availability during single-module maintenance.
• Hot-Swappable Design: Mounts onto Series C IOTAs with an angled insertion design, enabling online removal and replacement under power without disturbing field wiring.
• Onboard Diagnostics: Integrates self-diagnostic capabilities with CTools software monitoring to report hardware health and firmware status in real time.

Applications

• Continuous Process Monitoring: Interfacing standard high-level current and voltage field transmitters with Experion PKS control systems.
• Differential Signal Acquisition: Connecting noisy or non-isolated analog loops on channels 13 through 16 to eliminate ground loop interference.
• Control Loop Feedback: Supplying high-density analog process variables (PV) for flow, pressure, temperature, and level loops managed by C300 controllers.

Installation Guidelines

1. Pre-Installation Inspection: Confirm the exact part number 51405038-275 on the module side label and inspect the physical connector pins for damage prior to installation.
2. IOTA Mounting: Ensure the target Series C IOTA carrier is securely fastened inside the cabinet and properly bonded to protective earth ground.
3. Module Insertion: Align the module housing with the guide tracks of the target IOTA slot. Slide the module in at the standard 18-degree tilt angle until the locking latches click firmly into place.
4. Field Wiring Verification: Route high-level analog current or voltage input signal wires to the corresponding terminals on the IOTA. Ensure differential signal sources are correctly assigned to channels 13 through 16.
5. I/O Link Verification: Verify that the I/O Link cable connectors on the IOTA carrier are tight and assigned the correct physical address jumper matching the software setup.

Configuration / Commissioning / Replacement

• Control Builder Setup: Assign an AI-HL module block under the corresponding IOLINK master block in Honeywell Control Builder, matching the assigned hardware address on the IOTA.
• Redundant Module Replacement: When replacing an older revision CC-PAIX01 module in a redundant pair, verify hardware revision levels. For systems running Experion PKS R310 or later, ensure the controller patch level is updated before pairing older (rev <=K) and newer (rev >=M) hardware revisions.
• Online Switchover Check: Upon inserting a replacement module into an energized IOTA slot, monitor CTools to verify that firmware synchronization completes and the module status transitions to green/active.
