Honeywell 8C-PAINA1 Analog Input Module for Experion 8 Series

The Honeywell 8C-PAINA1 is a high-performance analog input module designed for the Experion 8 Series distributed control system. This 16-channel module accepts 4-20 mA current inputs from transmitters and sensing devices, providing high-accuracy signal conversion with HART communication capability. The module is engineered for industrial process applications requiring reliable, precise analog measurements with integrated diagnostic features.

Accuracy and Performance

The 8C-PAINA1 delivers exceptional measurement accuracy across its operating range. Hardware accuracy is specified at ±0.075% of full scale at 23.5°C ±2°C, and ±0.15% of full scale across the 0°C to 60°C operating temperature range. The module incorporates common mode rejection of 70 dB for DC to 60 Hz, ensuring reliable operation in electrically noisy industrial environments. Normal mode rejection is 19 dB at 60 Hz with a single-pole RC filter response of -3 dB at 6.5 Hz.

HART Communication Capability

Each analog input channel supports HART communication, enabling digital access to smart transmitter data. This capability allows operators to access additional device information including diagnostics, calibration data, and secondary variables without requiring separate HART multiplexers. The module integrates HART signals with the analog measurement, simplifying the system architecture while maintaining full access to smart device functionality.

Redundancy Configuration

The 8C-PAINA1 supports redundant operation through the IOTA (Input Output Termination Assembly). Redundancy is accomplished directly on the IOTA without requiring external cabling or redundancy control devices. Simply adding a second IOM to the IOTA creates a redundant configuration, ensuring continued operation in the event of a module failure. This approach simplifies system design and reduces installation complexity while maintaining high availability for critical process measurements.

Series 8 Design Features

The 8C-PAINA1 incorporates the innovative design features of the Series 8 I/O family:

• Vertical mounting orientation for improved wiring access from top and bottom

• Information circle for quick visual status indication

• Tilted design for enhanced heat management within high-density cabinets

• Integrated IOTA with detachable terminals for simplified field wiring

• Protection against input and output circuit shorts, reducing in-line fusing requirements

Field Power Options

The module offers flexible field power configuration. Field power can be supplied internally from the module's 24 V DC excitation source or externally from user-supplied power. This flexibility accommodates both 2-wire and self-powered transmitters. When using internal excitation, the module provides onboard power, eliminating the need for marshalling power supplies and associated wiring.

Galvanic Isolation

Safety isolation is provided with galvanic isolation of 1000 V AC RMS or 1000 V DC between system and field circuits. This isolation protects control system electronics from field wiring faults and ensures reliable operation in grounded or floating measurement configurations.

Applications

The 8C-PAINA1 analog input module is suitable for a wide range of process measurement applications:

• Pressure and temperature transmitter monitoring

• Flow measurement systems

• Level indication for tanks and vessels

• pH and conductivity analysis

• Process variable monitoring for safety instrumented functions

• General industrial automation and control

Environmental Protection

The module features conformal coating on electronic circuitry, providing protection against moisture, dust, chemicals, and temperature extremes. Coated modules (designated with 8C prefix) are recommended for applications where electronics must withstand harsh environmental conditions or where additional protection is required for long-term reliability.

Certifications and Standards

The 8C-PAINA1 complies with applicable industry standards for industrial control equipment and is designed for integration into Experion 8 Series distributed control systems. It meets requirements for electromagnetic compatibility and safety for use in industrial process environments.
