Overview

The 51304337‑100 (MU‑TAIH12) is a high‑density, screw‑terminal FTA designed for 16‑channel high‑level analog input with 1:1 redundancy. It mates with the MC‑TAIH12 IOP module and serves as the field‑side interface for pressure, flow, level, and temperature transmitters in Honeywell’s legacy DCS.
