Schneider Electric XPSVN3442HS — Safety module for zero spped detection of motor, category 3, 2 NO

The XPSVN3442HS Safety module is designed to ensure the safe operation of motors by providing zero-speed detection. It is classified as a Category 3 safety module, indicating that it provides a reliable level of safety functionality.

This safety module features 2 normally open (NO) safety contacts, which can be used to interrupt the power supply to the motor in case of a safety breach. These safety contacts help to prevent accidental start-up of the motor, ensuring the safety of personnel working with or around the motor.

In addition to the safety contacts, the XPSVN3442HS also includes 2 solid-state auxiliary outputs. These auxiliary outputs can be used to provide signals to other safety devices or control circuits, enhancing the overall safety and control of the motor system.

To ensure the proper operation of the safety module, it is recommended that the motor frequency be set to more than 50Hz. This ensures that the module can accurately detect the zero-speed condition of the motor, providing reliable protection against unintentional starts.

Furthermore, the XPSVN3442HS operates at a voltage of 115VAC, making it compatible with standard electrical systems.
