Schneider Electric Telemecanique LA2-D22 Time Delay Relay

Schneider Electric Telemecanique LA2-D22 Time Delay Relay is a front-mount time delay module designed to integrate with Telemecanique contactors in industrial motor control. It provides on-delay timing from 0.1 to 30 seconds, enabling controlled motor starting and process sequencing in MCCs, conveyors, pumps, compressors, packaging lines, HVAC systems, mixers, and automated production equipment. The LA2-D22 features 1 normally open and 1 normally closed contact, rated operational current 10 A, insulated up to 660 V (Ui), and can switch up to 690 VAC at 25–400 Hz (Ue). It uses screw clamp terminals for secure wiring and is rated for up to 5,000,000 mechanical cycles. It mounts on compatible Telemecanique contactors for streamlined installation. Minimum switching voltage 17 V and minimum switching current 5 mA define its operating thresholds. Common replacements include the LADR2 Time Delay Relay, making it a straightforward retrofit for existing installations.
