Metz Connect 11061325 KRA-M4/1 1NO 24 VDC coupling module content_copy

The coupling module 11061325 from Metz Connect is an electronic component type specifically designed for safe potential isolation between control logic and connected load. It serves as galvanic isolation in industrial control systems to prevent disturbances, voltage spikes, or dangerous potential differences between different circuits. The module is housed in a closed, compact series and enables safe and reliable signal transmission in automation technology applications. Connection is made via screw terminals, ensuring a secure and maintenance-friendly installation.

Applications

The coupling module is used in industrial applications where galvanic isolation between control level and load circuit is required. This includes, for example, manufacturing automation systems, machine controls, process engineering, or safety control systems. The isolation protects sensitive control components from disturbances caused by inductive or capacitive coupling and enables the connection of devices with different earth potentials. The module is designed for use in industrial environments where reliability and long-term stability are required.

Functions and Equipment in Detail

The coupling module 11061325 features an integrated protection circuit, providing additional protection against overvoltages and short circuits. This protection circuit ensures that the module remains stable even under adverse operating conditions and protects connected components from damage. The connection terminals are designed for a secure and durable connection, ensuring reliable signal transmission. The module is configured as a 1-closer, meaning it provides one switching contact for the switching operation.

Technology Explained Simply

Galvanic isolation is achieved through electronic coupling, which does not create a galvanic connection between input and output circuits. This prevents disturbance voltages or high potential differences from being transferred from the load side to the control level. The integrated protection circuit safeguards the module against overvoltages, such as those caused by lightning strikes or inductive voltage spikes. The screw terminals enable a mechanically stable connection that remains secure even under vibration or mechanical stress.

Compatibility and Accessories

For use with the coupling module 11061325, the switching bridge 850349-02 is available. This bridge can be used to connect the module’s terminals, for example, to extend switching functions or to bypass specific contacts. The bridge is 10-pole and fits the terminal geometry of the module. Combining it with the bridge increases flexibility in circuit design and allows individual adaptation to specific requirements.

Mounting and Installation

Mounting is done via screw terminals, ensuring a secure and durable connection. The module is compact and can be integrated into standard printed circuit boards or enclosures. The terminals are clearly marked to ensure error-free wiring. Installation requires no special tools, as the terminals can be operated with a screwdriver or suitable tool.

Advantages in Operation

The coupling module provides reliable galvanic isolation, enhancing the stability and safety of control systems. The integrated protection circuit reduces the risk of damage from overvoltages. The compact design enables efficient space utilization in enclosures. The screw terminals ensure a robust connection that remains secure even under industrial operating conditions. Combining it with the switching bridge 850349-02 extends the functionality and adaptability of the module to specific requirements.
