Product Overview

The RH924UQ is a DIN‑rail field termination block for Foxboro I/A Series and Foxboro Evo DCS, the hazardous‑location variant of RH924ZQ. It pairs with FBM244 simplex and FBM245 redundant 4–20 mA HART analog I/O modules, supporting 4 AI + 4 AO HART instrument loops. It adopts compression screw terminals, built‑in HART bypass jacks for offline instrument calibration without breaking control loops, and intrinsic safety compatible circuit layout for Class I Div.2 / Zone 2 hazardous environments. It simplifies field wiring separation between hot‑swappable FBM cards and transmitters / valve positioners, widely stocked for refineries, offshore platforms and petrochemical plants.
