The CAD50AD7 is a TeSys Deca control relay from Schneider Electric's TeSys range, built for switching control circuits in industrial panels. It carries five normally-open (5 NO) pole contacts and a 42 VAC standard coil, with snap-in terminals for wiring. The utilisation categories cover AC-15 (pilot duty), AC-14, and DC-13 loads, so it handles solenoid valves, contactor coils, and indicator lamps within its rated operational voltage up to 690 V.
The 5 NO contact arrangement means this relay switches five independent control circuits on closure, with no normally-closed auxiliary. For a panel builder, that is five discrete pilot-duty outputs from one 45 mm wide device — a clean fit on a DIN rail when you need multiple start/stop or permissive signals from a single coil. Operating temperature spans -40 to 60 °C, with derating allowed up to 70 °C. Storage range of -60 to 80 °C means the relay tolerates warehouse extremes without degradation. The TH protective treatment per IEC 60068 confirms the PCB and coil withstand humid, tropical conditions — relevant for coastal or untreated plant-floor storage. Mechanical robustness is specified: the relay withstands 10 Gn shocks for 11 ms in the open state and 15 Gn closed, plus vibration at 2 Gn (open) and 4 Gn (closed) across 5–300 Hz. That is enough for most industrial machinery, including conveyors and compressors mounted near the panel. The IP2X front-face protection per VDE 0106 means fingers are blocked from live parts — a basic safety requirement for operator-access panels.
The CAD50AD7 is certified to EN/IEC 60947-5-1, UL 60947-5-1, CSA C22.2 No 60947-5-1, GB/T 14048.5, and JIS C8201-5-1. That covers the main global jurisdictions for control circuit devices — Europe, North America, China, and Japan. For a quality-documentation check, the relay carries the TH marking for tropical environments and the IP2X front-face protection. The operating altitude rating of 0...3000 m means it is suitable for installations up to moderate high-altitude sites without derating.
Physical integration
Dimensions are 45 mm wide, 107 mm high, and 93 mm deep. For a panel OEM planning gland-plate fill or busbar clearance, the 93 mm depth is the critical dimension behind the mounting surface.
