Honeywell CC-PAIX02
Product Name: 16-Channel High-Level Analog Input Module (Series C)
Product Overview: The CC-PAIX02 (part number 51405038-475) is a high-level analog input module within Honeywell’s Experion Series C I/O family. It provides reliable, high-precision acquisition of current and voltage signals from field transmitters and sensors, converting them into digital values for C300 controller processing. The CC-PAIX02 is the enhanced successor to CC-PAIX01 with differential input capability on all 16 channels.

Functional Features:
- Extensive self-diagnostics monitoring internal functions continuously
- Optional redundancy with compatible IOTA models for critical processes
- Non-incendive field power meeting Class 1, Div 2 safety standards
- Fast loop scan reducing control delays
Working Principle: The module accepts conditioned voltage or current signals from field devices, conditions them through instrumentation amplifiers (with differential inputs on all 16 channels for superior noise rejection), and digitizes via 16-bit ADCs. The digital values are transferred over the Series C backplane to the C300 controller.
Application Scenarios: Accurate data acquisition for critical analog signals in process control; suitable for noisy industrial environments requiring high common-mode rejection; hazardous area installations (Class 1, Div 2).
Installation & Usage Notes:
- Install on a compatible Series C IOTA within a C300 I/O rack.
- Use shielded twisted-pair wiring for current loops; terminate shield at a single point on the enclosure ground bus.
- Ensure field power circuits are de-energized before module insertion.
- For redundant configurations, pair with CC-TAIX11, CC-GAIX11, or CC-TAID11 IOTAs.
