Schneider Electric CA2-DN22E Control Relay

The Schneider Electric Telemecanique CA2-DN22E / CA2-DN40E Control Relay is an industrial-grade device that provides reliable switching for auxiliary control circuits, PLC interfaces, interposing relays, and signaling functions within control panels, motor control centers, machine tools, packaging equipment, conveyors, and process automation installations. The CA2-DN22E configuration provides 2 normally open + 2 normally closed contacts, while the CA2-DN40E offers 4 normally open contacts, enabling flexible PLC outputs and interlock schemes. Rated up to 500 VAC and 6 A, with a thermal current of 10 A, it features Ui 1000 V and Uimp 8 kV; it operates at 50/60 Hz (coil code dependent). Mounting options include 35 mm DIN rail or panel mounting with screw clamp terminals. Designed to IEC 60947-5-1, this control relay suits industrial electrical control systems requiring dependable auxiliary switching and PLC interfacing. Common replacements include Schneider Electric CA2DN22M7, CA2DN40M7, and Siemens 3RH2122-1AK60.
