Honeywell MC-PAIH03 51304754-150 Analog Input Processor Board

The Honeywell MC-PAIH03 51304754-150, also cataloged as the MC-PAIH03 Analog Input Processor Board, operates as a dedicated hardware component for analog signal acquisition and conversion within Honeywell process control systems. The module receives differential voltage and current inputs from field instrumentation, performs analog-to-digital conversion, and transfers processed measurement data to the control platform for supervisory and regulatory control functions.

Hardware Specifications

Channel-to-Channel Signal Acquisition Architecture

The MC-PAIH03 performs analog measurement acquisition from field instruments and converts incoming process signals into digital data suitable for controller processing. The module supports differential signal measurement across sixteen input channels, allowing acquisition of process variables such as temperature, pressure, flow, and level from connected instrumentation.

The integrated analog-to-digital conversion architecture supports multiple industry-standard voltage and current ranges. Differential input measurement assists in reducing susceptibility to common-mode noise and improves signal integrity when interfacing with remote field devices.

The module scans each channel at a rate of four samples per second and transfers processed measurement values to the associated Honeywell control platform for monitoring, alarming, trending, and control execution.

Analog Measurement Accuracy and Process Integration

The MC-PAIH03 utilizes a 16-bit conversion architecture with specified utilization of 14 bits for process measurement applications. The published accuracy specifications support precise acquisition of low-level analog signals commonly found in process industries.

Compatibility with multiple Honeywell Field Termination Assemblies allows the processor board to be integrated into a variety of analog input cabinet configurations while maintaining standardized field wiring interfaces.
