Schneider Electric LA4DT2U Push Button Contact Block

Schneider Electric LA4DT2U is an electronic timer module designed as an accessory for Schneider Electric TeSys push‑button and contact‑block assemblies, providing an on‑delay function to energize a load after a fixed interval. It delivers a programmable delay of 1.5 to 30 seconds and operates from a supply voltage range of 24 to 250 V, supporting both AC and DC control signals (50/60 Hz variants are listed for applicable regions). This timing module integrates with the LA4D/TeSys family in control panels, enabling sequencing, interlock timing, and timed energization of a contactor coil in industrial automation applications. Use cases include timed start sequences and safety interlocks in motor control or process automation where a compact, plug‑in timer is required.
