Frequently Asked Questions
What does 1NO 1NC mean in the LADN11C auxiliary contact module?
1NO means one Normally Open contact and 1NC means one Normally Closed contact. The LADN11C module provides both types, enabling flexible electrical control and signal expansion for various automation applications.
How is the auxiliary contact module installed on an AC contactor?
The module uses a modular clamping or front/side mounting structure that snaps directly onto compatible AC contactors. No additional tools are required, making installation and removal fast and straightforward.
What AC contactor series are these auxiliary contact modules compatible with?
These auxiliary contact modules, including LADN series (front mounting) and LAD8N series (side mounting), are designed for use with standard CJX2-D series AC contactors. Side mounting models are suitable for contactors below D170 size.
What is the maximum number of contacts available per module?
The modules are available in 2-contact and 4-contact configurations. The 4-contact models (e.g., LADN22C, LADN40C, LADN04C) offer various NO/NC combinations to suit complex control circuit requirements.
Are these auxiliary contact modules suitable for PLC signal feedback applications?
Yes. These modules are widely used in PLC signal feedback, circuit interlocking, indicator control, and various industrial automation systems, providing stable and reliable signal output for control panels and automation equipment.
What materials are used to ensure safety and durability of the modules?
The modules use high-conductivity alloy contacts for reliable switching performance and feature a flame-retardant insulated housing that resists high temperatures and aging, ensuring long service life and enhanced operational safety in demanding industrial environments.
