Schneider Electric LADR2 Time Delay Relay Module

Schneider Electric's LADR2 is a TeSys D time-delay auxiliary contact block that adds a precise off-delay timing function to compatible control relays and contactors, such as LC1D and LC1F series. The module provides one normally open (NO) and one normally closed (NC) auxiliary contact, allowing basic sequencing and interlocking in motor-control circuits. It is designed for front mounting on Schneider Electric TeSys D devices and features front-panel screw-clamp terminals for straightforward wiring. The LADR2 clips to the right-hand side of the control relay, simplifying installation and minimizing panel space. Timing is specified as an off-delay in the range 1–30 seconds, enabling delayed activation or de-energization of the connected circuit after the input signal is removed. This accessory is suitable for machine automation where a compact, bolted-on delay element is preferred over separate timers, delivering predictable sequencing without additional devices and preserving the control circuit’s discreteness and reliability.
