MC-PAIH03 51304754-150 | Honeywell High Level Analog Input Processor

Product Overview

The Honeywell MC-PAIH03 (51304754-150) operates as a high-density High Level Analog Input (HLAI) processor within the Honeywell Process Manager architecture. This 100% Brand New and original module interfaces with 16 differential input channels, supporting a variety of voltage and current signals from 2-wire or self-powered transmitters. It converts field signals into high-resolution digital data, serving as the backbone for precision process monitoring in oil & gas, chemical, and power generation facilities.

Technical Specifications

Engineering Advantages

• Superior Signal Integrity: The 70 dB Common Mode Rejection Ratio (CMRR) and integrated single-pole RC filtering mitigate electrical noise interference. This ensures stable readings even in environments with heavy electromagnetic signatures from large motors or switchgear.

• Broad FTA Compatibility: This processor integrates seamlessly with a wide array of Field Termination Assemblies (FTAs), including MU-TAIH02, TAIH12, TAIH52, and the TAIH03/13/23/53/62 series. This flexibility allows for rapid deployment in existing infrastructure.

• Rugged Fault Protection: The hardware withstands up to ±30V differential input without sustaining damage. This robust protective circuitry prevents module failure during field-side wiring errors or transient surges common in industrial startups.

• High-Precision Conversion: By utilizing 14 bits of a 16-bit A/D converter, the MC-PAIH03 delivers a level of granularity essential for critical control loops where minor signal fluctuations impact product quality.

• Standardized ANSI/IEEE Compliance: The module meets ANSI/IEEE C37.90.1-1978 surge withstand standards, providing verifiable resilience against high-voltage transients on the signal lines.

FAQs

• Which Field Termination Assemblies (FTA) work with the MC-PAIH03?

  The MC-PAIH03 supports a broad range of FTAs including MU-TAIH02, TAIH12, TAIH22, TAIH52, TAIH62, and the newer TAIH03, TAIH13, TAIH23, and TAIH53 models. Always verify the specific terminal requirements for your transmitter type.

• How does the module handle 4-20 mA current loops?

  The processor accepts 4-20 mA signals by passing the current through a 250 Ω precision resistor, converting the signal to a 1-5V range for the A/D converter. Ensure your FTA includes the necessary precision resistors for current loop operation.

• What is the sampling window for the 16 channels?

  The hardware scans all 16 channels within a 250 ms window, providing 4 samples per second for every channel. This deterministic scan rate ensures synchronized data acquisition across all process points.

• Is this a refurbished or original Honeywell part?

  We supply only 100% Brand New units in original factory packaging. This ensures the processor meets the maximum hardware accuracy of ±0.075% full-scale and carries the full operational lifespan expected of new industrial hardware.
