The CAD32AD7 is a TeSys Deca control relay from Schneider Electric — a 3-pole NO plus 2-pole NC contact block rated for control-circuit switching in industrial panels. The 3 NO + 2 NC pole composition gives you three normally-open auxiliary contacts for signalling or interlocking and two normally-closed for safety or status feedback, all in one 45 mm wide package. It carries utilisation categories AC-15, AC-14, and DC-13 per IEC 60947-5-1. AC-15 is the relevant rating for solenoid-operated loads (contactors, valves) above 72 VA; AC-14 covers smaller solenoid loads below 72 VA. DC-13 covers DC solenoids and electromagnetic brakes. For a control relay, these ratings tell you the switching capability under inductive load — not just resistive make/break. The 42 VAC standard coil matches legacy control transformer secondaries common in older panel designs or specific OEM specs. Snap-in terminals (the 'D' suffix in the order code) mean the relay clips directly onto a DIN rail without tools — quick to install or swap during a line changeover. Rated for operation from -40 °C to 60 °C, with derating allowed up to 70 °C. Storage range is -60 °C to 80 °C. The IP2X front-face protection (per VDE 0106) means the front is touch-safe against fingers — standard for enclosed panel-mount relays, not for open washdown areas.
At 45 mm wide, 107 mm tall, and 93 mm deep, this relay occupies a standard DIN-rail footprint. Mechanical robustness is specified: the relay withstands 10 Gn shocks for 11 ms when open (contacts not carrying current) and 15 Gn when closed. Vibration resistance is 2 Gn from 5 to 300 Hz open, 4 Gn closed. These figures matter for applications on conveyors, packaging machinery, or mobile equipment where the panel sees continuous vibration. Operating altitude is rated up to 3000 m — no derating needed for most installations, but worth noting for high-altitude sites above that threshold.
It carries approvals 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 major global regulatory jurisdictions — IEC/EN for Europe, UL/CSA for North America, GB/T for China, JIS for Japan. The protective treatment is TH conforming to IEC 60068, meaning it's treated for tropical/humid environments.
