Product Description
The Honeywell 8C-TAIDA1 51307131-175 is a coated Input Output Termination Assembly (IOTA) designed to support the Series 8 Analog Input Module in differential or single-ended configurations with HART communication capabilities. It is tailored for non-redundant systems and provides robust integration with Experion PKS C300 controllers. The IOTA allows seamless connection between field analog instruments and the controller’s analog input modules by facilitating signal termination and conditioning within a compact and easily mountable hardware unit.
This module is optimized for high-level analog inputs, offering both voltage and current sensing capabilities, and is conformal-coated for operation in harsh environments (G3 classification).
