Timer Module for Industrial Control

The Schneider Electric LADR4 is an IEC timer module designed for industrial electrical control and automation systems. It provides a single normally open and a single normally closed contact for switching circuits with an adjustable off-delay function. The unit operates at a maximum voltage rating of 690V AC and is compatible with the TeSys Deca series.

Front Mounting with Screw Clamp Terminals

This module mounts on the front of a compatible starter, integrating directly into the control panel layout. It uses screw clamp terminals for secure wiring connections without the need for specialised tools. The timer frees up DIN rail space by attaching directly to the contactor, simplifying panel assembly and reducing overall component footprint.

Operating Temperature up to 158 Degrees F

The timer module functions within a maximum operating temperature of 158 degrees F, suitable for typical industrial enclosure environments. The adjustable delay ranges from 10 to 180 seconds, allowing precise timing control for motor starting or process sequences. Power consumption remains low as the device only draws control circuit current during operation.
