Technical Specifications Rated working voltage DC 24V. Operating temperature range ‑40℃ ~ +85℃. Protection grade IP20. Adopts DIN‑rail installation structure. Screw‑type wiring terminals for signal wiring. Humidity adaptability 5%‑95%, non‑condensing.
Functional Features Completes impedance matching for analog signal loop. Suppresses signal reflection interference from long‑distance transmission. Compact size is friendly for cabinet internal layout. Simple mechanical structure supports convenient on‑site replacement.
Application Scenarios Chemical synthesis workshop control cabinet, petrochemical refining DCS system, oil‑gas field automation control equipment, thermal power plant auxiliary instrument control cabinet.
Performance Parameters Resistance value keeps stable under wide‑range temperature working condition. Can adapt to uninterrupted long‑time industrial operation. Mechanical property meets industrial vibration resistance standard.
Structural Characteristics Compact industrial‑grade modular shell. DIN‑rail buckle structure for quick mounting and dismounting. Screw‑type wiring terminals arranged on side face. Internal high‑precision resistance components with anti‑heat‑aging processing.
Working Principle Foxboro RH926GK is connected to analog signal circuit, provides matched load impedance for transmission loop. It weakens signal distortion phenomenon brought by long‑distance cable transmission, lowers signal reflection noise, so that field analog signal can be reliably transmitted to DCS control hardware.
Installation Requirements Install on standard DIN‑rail inside control cabinet. Tighten all wiring terminal screws. Keep away from high‑voltage interference cables. Ensure cabinet ventilation and heat‑dissipation performance.
