The CAD50AGD is a TeSys Deca control relay from Schneider Electric, built for switching control circuits — think PLC outputs driving contactor coils, solenoid valves, or signal lamps in a panel. It carries 5 normally open (5 NO) pole contacts, rated for operational voltages up to 690 V, with a standard 125 VDC coil. The utilisation categories cover AC-15 (inductive loads above 72 VA), AC-14 (solenoid loads), and DC-13 (DC solenoids and contactors), so it handles the typical mix of control devices on a line.
The 5 NO contact configuration means all five contacts are normally open — no NC auxiliary for a feedback loop unless you add a separate block. That matters if your safety circuit expects a mechanically linked NC mirror contact; this relay alone won't provide it. The AC-15 and DC-13 ratings tell you the contacts are tested for switching inductive DC loads, which is harder on contacts than resistive AC loads — so it's a legitimate choice for DC solenoid valves or DC contactor coils, not just AC pilot duty. That covers most indoor panel environments, even near ovens or steam lines, as long as the panel has some airflow. The TH protective treatment per IEC 60068 means the relay is treated for tropical humidity — important if the panel goes into a non-conditioned space in a humid climate. Mechanical robustness specs: the relay withstands 10 Gn shocks for 11 ms when open, 15 Gn when closed, and vibrations of 2 to 4 Gn across 5 to 300 Hz. That's enough for most industrial machinery — conveyors, pumps, compressors — but if the relay mounts directly on a vibrating screen or a stamping press, you'd want to check the specific shock profile against these numbers. IP2X front-face protection per VDE 0106 means it's finger-safe from the front when installed in a panel — standard for control relays.
The CAD50AGD is certified to EN/IEC 60947-5-1 (the main standard for control circuit devices), UL 60947-5-1, CSA C22.2 No 60947-5-1, GB/T 14048.5 (China), and JIS C8201-5-1 (Japan). That means it's accepted in European, North American, Chinese, and Japanese markets — no extra paperwork for a global machine builder. Operating altitude is rated to 3000 m, so it works in high-altitude plants without derating.
