Schneider Electric LAD4DDL Industrial Relay Module

LAD4DDL is a compact flyback diode (freewheel diode) suppression module for Schneider Electric TeSys D control relays, designed to absorb inductive kick from DC coils and protect drive electronics and contacts. It is rated for DC coil voltages from 24 to 250 V, enabling suppression across common TeSys D coil configurations, and it weighs about 6.4 g. The module clips onto the top of the relay to provide an integrated suppression path, simplifying wiring and reducing component count in control panels; it is intended for use with TeSys D relays to suppress transient surges and extend coil and contact life in industrial automation applications.
