Square D LADR2 Programmable Relay Module

Schneider Electric's LADR2 is a TeSys Deca time-delay auxiliary contact block that adds a compact, off-delay timing function to a TeSys Deca contactor. It provides 1 normally open and 1 normally closed contact (1NO + 1NC) with an adjustable off-delay of 1 to 30 seconds, enabling simple sequencing and timed interlocks in control circuits. The unit features front-facing screw-clamp terminals for easy wiring and field servicing, and is designed to integrate with TeSys Deca/TeSys D systems for streamlined installation. Used in industrial machines, conveyors, and process lines, the LADR2 supports controlled dwell times and orderly shutdowns by keeping a circuit energized for a short, programmable interval after input changes. As a TeSys accessory, it complements the Deca platform by delivering a reliable, maintenance-friendly timer function in a compact module that fits alongside standard contactors.
