Circuit d'amortissement LC1/LP1 22 VAC LA4DFB

Interface module for TeSys Deca contactors – reliable circuit control

This interface module, designed to work with TeSys Deca LC1D09-D150 contactors, is a key element in control systems. It allows you to control contactor coils using a 24V DC signal, ensuring reliable and precise operation. This solution is ideal for both professional installers and end-users looking for an effective way to control electrical circuits.

Functionality and application

The LA4DFB module acts as a signal amplifier, allowing you to control contactors with 24-250V AC coils. Mounting is done directly on the contactor or via the LAD4BB (for LC.D09-D38), LAD4BB3 (for LC.D40A-D80A) or directly to LC.D80-D115 adapter. Using this module allows for easy integration with existing control systems and provides flexibility in circuit configuration. A 24V DC input signal activates an electromechanical relay, which in turn switches the contactor on or off.

Advantages and benefits

• Versatility: Compatible with a wide range of TeSys Deca contactors (LC1D09…D150).

• Simple installation: Direct or adapter mounting options make installation and maintenance easier.

• Reliability: The electromechanical relay provides stable and reliable operation in various working conditions.

• Safety: Compliance with IEC 60255-5 standards and UL and CSA certifications guarantee safe use.

• Status indicator: A built-in LED indicates the module's activity status, facilitating diagnostics and system monitoring.

• Ecology: The product meets Green Premium requirements (RoHS/REACH), demonstrating a responsible approach to the environment.

• Compact dimensions: A height of only 12 mm allows installation in limited space.

Design and operating parameters

The LA4DFB module is characterized by a solid construction and high quality workmanship. It is designed to operate in an ambient temperature from -25°C to 55°C, ensuring its reliability in various industrial conditions. The diodes used protect the circuit against overvoltage, and the housing protects against electromagnetic interference. The operating voltage is from 24 to 250 V AC with a control voltage of 24 V DC, and the current consumption is 25 mA at 20°C. This ensures efficient operation with minimal energy consumption.
