Honeywell CC-PAIN01 Analog Input Module

Description

The Honeywell CC-PAIN01 is a high-level analog input module designed for precise acquisition of current signals (4-20 mA) from sensors and transmitters in industrial automation systems, particularly within Honeywell’s Experion Series-C platform. This module is widely used in petrochemical, power generation, water treatment, and refining plants where continuous monitoring of process variables like pressure, temperature, and flow is critical. The CC-PAIN01 supports 16 independent input channels and operates reliably in hazardous environments compliant with Class 1, Division 2 safety standards by providing non-incendive, loop-powered channels without requiring external marshalling.

Designed for direct integration with the Input/Output Termination Assembly (IOTA), this module simplifies installation while reducing control cabinet footprints. The CC-PAIN01 offers 16-bit resolution with high accuracy (±0.075% full scale at ~24°C) and robust diagnostics that detect open circuits, short circuits, and channel-level faults in real time—preventing unexpected downtime through early fault alerts. It also supports redundant configurations paired with specific IOTA models, enabling automatic failover without manual intervention, which maximizes system availability in critical applications.

Electrical isolation up to 1000 VDC protects signal integrity in electrically noisy industrial environments. The module operates over a temperature range from 0 to 60°C, uses a current-limiting circuit for intrinsic safety, and supports 2-wire or self-powered transmitters. The maximum recommended signal wire length is about 305 meters (1000 feet) for accurate signal measurement. Maintenance requires regular calibration (typically annually) to maintain accuracy, with calibration cycles adjustable to environmental conditions.

Compatibility with redundant and non-redundant IOTA models such as CC-TAIN11 and CC-TAIN01 enables flexible system design tailored to availability requirements. Related modules include the Honeywell CC-PAIH02 and CC-PAIX02, which provide voltage signal inputs, recommended if voltage measurement is needed.

Installation should focus on proper grounding, adherence to hazardous area safety standards, and avoidance of excessive wire length to maintain signal fidelity. Monitoring diagnostic signals and scheduling firmware updates are essential for long-term reliability.
