🔴The Honeywell 05701-A-0330 is a High-Level Analog Input / HART input module for the Experion Series-C I/O system (Experion PKS / PlantCruise). It provides 16 analog input channels accepting 4–20 mA signals from both traditional transmitters and HART devices, with HART data available for status, configuration, and as additional process variables. Designed for fault-tolerant process control, it features per-channel isolation, independent current-limiting protection, and 16-bit resolution — a standard spare part for installed Honeywell Experion plants.
