The Honeywell MC-PAIH03 is a high-level analog input processor module commonly used in industrial automation and process control systems, particularly within Honeywell’s Experion and TDC 3000 Distributed Control Systems. Designed for precision and reliability, the MC-PAIH03 supports up to 16 differential analog input channels capable of handling various input types, including voltage (0-5V, 1-5V, 0.4-2V) and current (4-20 mA using a 250-ohm resistor). This flexibility enables it to interface with a wide range of sensors and transmitters used for monitoring critical process variables such as temperature, pressure, and flow rate.
Technically, the MC-PAIH03 features 16-bit A/D conversion with 14 bits effectively utilized for high resolution and accuracy, rated at ±0.075% full scale at normal operating temperatures. It incorporates excellent common-mode rejection of 70 dB and crosstalk suppression of 60 dB, ensuring signal integrity even in electrically noisy environments. The module scans inputs at about four samples per second, delivering timely data for real-time process monitoring and control. Its rugged design supports operation in temperatures from -40°C to 85°C, with galvanic isolation to prevent ground loops and electrical interference.
