The CAD50FC7 is a TeSys Deca control relay from Schneider Electric, configured with 5 normally open (NO) contacts and a 127V AC standard coil. It's designed for control circuit switching duties in industrial panels, rated for utilisation categories AC-14, AC-15, and DC-13 — meaning it handles solenoid loads, electromagnetic clutches, and contactor coils in both AC and DC control loops. The relay carries approvals across EN/IEC 60947-5-1, GB/T 14048.5, UL 60947-5-1, CSA C22.2 No 60947-5-1, and JIS C8201-5-1, so it's accepted in European, North American, and Asian installations. Front-face protection is IP2X per VDE 0106 — finger-safe when mounted in an enclosed panel.
Mechanical robustness is specified for shock and vibration: the relay withstands 10 Gn for 11 ms in the open position, 15 Gn for 11 ms closed, and vibration at 2 Gn (open) / 4 Gn (closed) across 5–300 Hz per IEC 60068-2-27 and -2-6. Operating temperature spans -40 to 60 °C, with derating allowed up to 70 °C. Storage range is -60 to 80 °C. Altitude rating is 0–3000 m without derating. Protective treatment is TH per IEC 60068, meaning it's tropicalized against heat and humidity — relevant for installations in warm, damp environments like Southeast Asia or coastal plants.
