Schneider Electric LADN40 Programmable Logic Controller Module

LADN40 is a four‑pole normally open auxiliary contact block for Schneider Electric TeSys D/Deca contactors, providing additional signaling contacts that can be wired to interlock devices, sensors, or control circuits. It is designed for front mounting on the TeSys D family and uses screw‑clamp terminals, enabling quick, secure wiring in panel or DIN rail assemblies. The LADN40 is compatible with TeSys D LC1D series contactors (LC1D09 through LC1D150), expanding the control logic options for starting, stop signals, status indication, and interlock applications in industrial automation. This compact auxiliary block remains a straightforward, field‑attachable accessory that preserves the same footprint as the main contactor while delivering four normally open contact paths for discrete control signals.
