The Schneider CAD50AJL is a TeSys Deca control relay with five normally-open (5 NO) pole contacts, designed for control-circuit switching up to 690 V. It uses a 12 V DC low-consumption coil and terminates via snap-in terminals — no tools needed for the connection, which matters when you're swapping a relay in a crowded panel without losing the screwdriver down the backplane. Rated for utilisation categories AC-15, AC-14, and DC-13, so it handles solenoid and contactor coils (AC-15), small electromagnetic loads (AC-14), and DC inductive loads like brake coils or clutch actuators. The DC-13 rating is what you check when the relay drives a DC valve bank — not every control relay carries it.
Measures 45 mm wide, 107 mm tall, 93 mm deep — standard TeSys Deca footprint that clips onto a DIN rail. The 93 mm depth means it clears a 100 mm deep enclosure without the front cover pressing on the coil terminals. IP2X on the front face keeps fingers out per VDE 0106; fine for a closed panel, not rated for washdown. Operates from -40 °C to 60 °C ambient, with derating allowed up to 70 °C. Storage range is wider at -60 °C to 80 °C — that's the shipping and warehouse limit, not the running limit. Mechanical robustness is specified: shocks up to 10 Gn (11 ms) when open, 15 Gn when closed; vibrations 2 Gn open, 4 Gn closed across 5–300 Hz. That's enough for most industrial machinery but not for direct mounting on a large reciprocating compressor — check the vibration profile if that's the mount point.
Compliant with 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. The UL and CSA marks mean it's accepted in North American panels without a separate evaluation. Protective treatment is TH per IEC 60068 — tropicalised for humid environments, which matters in a brewery or paper mill control cabinet.
