Honeywell 8C-PAIH51 HART Analog Input Module

Description

The Honeywell 8C-PAIH51 HART Analog Input Module is a critical I/O component for industrial automation systems, designed to bridge field devices and central control units to enable precise data acquisition and signal conversion. Key technical specifications include a 4-20 mA input signal range, 16-bit ADC resolution, and a configurable 250 samples per second per channel sampling rate. It provides a 24 VDC (32 pt) output signal with current-sinking digital outputs and electronic short-circuit protection, and operates on a 220V working voltage with a 50/60 Hz output frequency. The module features robust isolation: 3000VAC isolation between channels and 1500VAC isolation between power and signals, ensuring reliable performance in harsh industrial environments. It supports optional HART protocol and Foundation Fieldbus (with external gateway), and has an IP20 protection rating for rack-mounted installations, complying with NEMA TS2 and IEC 61131-2 standards. Operating temperature ranges from -20 degrees Celsius to 70 degrees Celsius, and it holds certifications including ATEX Zone 2, UL/cUL Class I Div 2, CE, and FCC. Ideal for precision data collection, it is commonly used in oil and chemical, pharmaceutical, food and beverage, and energy power applications for monitoring and controlling variables like temperature, pressure, pH, and liquid level.
