Schneider LADT2: Time Delay Auxiliary Block

Introduction

The Schneider LADT2 is a time delay auxiliary block designed to add delayed switching functionality to contactors within Schneider Electric’s TeSys range. With this device, users can configure timed delays for opening or closing auxiliary contacts, which is useful for controlling sequences in automation and motor control applications. The LADT2 is valued for its precision, durability, and compatibility with a wide variety of contactors, making it a go-to component for applications that require controlled timing and sequential operations.

Key Features of Schneider LADT2

• Time Delay Functionality: The LADT2 enables users to set a time delay for switching auxiliary contacts, supporting both “On-Delay” (time before the contact closes) and “Off-Delay” (time before the contact opens) operations.
• Adjustable Time Range: It offers an adjustable time range, typically from 0.1 to 30 seconds, allowing for fine-tuned control over timing in automation sequences.
• Compatibility with TeSys Range: The LADT2 is compatible with TeSys D and K contactors, making it easy to integrate into existing Schneider Electric systems.
• Easy Clip-On Installation: Designed for easy mounting, the LADT2 attaches directly to the contactor, requiring no extra tools or components.
• Durable Build: Constructed to withstand industrial conditions, the LADT2 performs reliably in environments that require precise timing control under demanding conditions.

Applications of Schneider LADT2

1. Motor Control Systems: The LADT2 is commonly used in motor control applications where delayed startup or shutdown is needed, reducing the risk of power surges or system damage.
2. Conveyor Systems: In automated conveyor systems, time delay relays like the LADT2 help in controlling the sequence of belt movements, ensuring materials are transported smoothly without overlap.
3. HVAC Systems: The LADT2 can be used to control timed sequences in HVAC systems, providing staggered starts to reduce load on the power system.
4. Industrial Automation: The LADT2 enables sequential control, essential in processes where one operation must complete before another begins.
5. Pumping and Water Treatment Plants: Delayed switching is beneficial in controlling pumps and valves, ensuring smooth transitions and protecting equipment from sudden pressure changes.

Benefits of Schneider LADT2

• Improved Process Control: By adding timed delays, the LADT2 allows for precise control of sequences, enhancing efficiency and safety in automated systems.
• Easy to Install and Configure: With a clip-on design and adjustable time settings, the LADT2 is user-friendly and quick to set up, reducing installation time.
• Increased Protection for Equipment: Time delays help to prevent power surges and excessive wear on equipment, increasing the lifespan of motors and other components.
• Enhanced Safety: Delayed control can prevent accidental starts and stops, ensuring safer operation in industrial environments.
• Space-Saving Design: The compact form factor makes the LADT2 suitable for use in control panels with limited space, providing enhanced functionality without requiring additional panel area.
