Honeywell 51204170‑175 HLAI‑STI FTA High‑Level Analog Input Field Terminal Assembly

Product Description

The 51204170‑175 is a field terminal assembly (FTA) designed for Honeywell Experion PKS DCS HLAI high‑level analog input IOP card. It serves as physical wiring interface between field 

transmitters and HLAI processor card, receiving 4‑20mA analog signals from on‑site instruments and transferring signals to corresponding I/O module through dedicated ribbon cable. This terminal 

unit integrates signal conditioning, over‑voltage protection and channel isolation functions, supports multiple signal wiring modes. Widely deployed in petrochemical, oil & gas, power plant and 

chemical processing DCS control cabinets, it acts as essential maintenance spare for existing Experion PKS system overhaul and component replacement.
