Delayed auxiliary contact block 0.1-30s TeSys 1NO 1NC screw terminals LADR2

Auxiliary contact block LADR2 is a reliable solution with a time delay, designed to work with TeSys D (LC1D, CAD) and TeSys F (LC1F, CR1F) contactors. It enables the implementation of delayed disconnection functions, which is particularly useful in applications requiring sequential start-up or shutdown of devices. The block is equipped with one normally open contact (1NO) and one normally closed contact (1NC), providing flexibility in control circuit configuration.

Functionality and application

This contact block is a component dedicated to industrial automation and control systems. Its main feature is the ability to set the disconnection delay time in the range of 0.1 to 30 seconds. Thanks to this, functions such as:

• Delayed shutdown of fan motors after the process is completed.
• Sequential start-up of devices where order is critical.
• Implementation of timing functions in control circuits.
• Ensuring smooth shutdown of the load, minimizing the risk of damage.

can be realized.

Front mounting with snap-on ensures quick and secure installation, and screw terminals allow connection of wires with a cross-section adapted to the installation requirements. The LADR2 block is compatible with a wide range of TeSys contactors, making it a versatile element of control cabinet equipment.

Characteristics and advantages

The LADR2 block is distinguished by its high reliability and durability confirmed by numerous certificates (IEC, UL, CSA, CCC, EAC). Compliance with the Green Premium standard demonstrates a commitment to environmental protection – the product meets RoHS and REACH requirements and provides transparent information about its environmental impact. Additionally:

• Wide time setting range: from 0.1 to 30 seconds allows precise adjustment to application needs.
• High switching frequency: the ability to switch once per second provides flexibility in dynamic processes.
• High mechanical strength: 5 million operating cycles guarantee long-term, trouble-free operation.
• Versatility: compatible with TeSys D and F contactors makes it easy to integrate with existing installations.
• Safety: has appropriate certificates and meets safety standards.
• Built-in mirrored contacts: increase the functionality and application possibilities of the contact block.

The LADR2 block is a solid and reliable solution for professionals looking for high-quality components for control and industrial automation systems. Its versatility and ease of installation make it an ideal choice for both installers and end-users.
