Schneider Electric Telemecanique LA4DWB Interface Module

The Schneider Electric Telemecanique LA4DWB Interface Module is a solid-state interface amplifier that bridges 24 VDC control signals to AC-operated TeSys Deca contactors, enabling PLCs and other low-voltage controls to drive AC loads in motor control centers, conveyors, pumps, compressors, packaging machines, and industrial control panels. Key specs include a 24 VDC supply (Us), a control circuit voltage range of 5–30 VDC at 20°C, and a control-to-control voltage rating of 24–250 VAC at 50/60 Hz, with 250 V insulation and an 8 A conventional free-air current rating; it draws 8.5–15 mA at 20°C and provides 20 million operating cycles at 240 VAC, accompanied by a LED status indicator and top-mounting on compatible TeSys Deca LC1D contactors. The module uses connector terminals for 1–2.5 mm² conductors, is compatible with TeSys Deca LC1D09...LC1D115 devices, and adheres to IEC 60255-5 and IEC 60947-5-1 standards with UL and CSA certifications.
