Schneider Electric Preventa XPS Contact Expansion Module, 24V AC/DC, 4 NO + 2 NC, Spring Terminals

The Schneider Electric Preventa XPS contact expansion module is a high-performance safety component designed to extend the number of available contacts in industrial safety systems. Operating on a 24V AC/DC power supply, this module provides 4 normally open (NO) and 2 normally closed (NC) contacts, allowing for flexible configuration within complex machine safety circuits. It is engineered to meet the rigorous requirements of Category 4 safety applications, ensuring reliable operation and enhanced protection for personnel and equipment.

Advantages

This expansion module offers significant benefits for industrial automation by providing a reliable way to increase safety output capacity without compromising system integrity. The inclusion of spring terminals facilitates quick and secure wiring, reducing installation time and ensuring a vibration-resistant connection that maintains signal continuity in demanding environments. Its compact design allows for efficient use of space within control cabinets, while its compatibility with standard safety controllers makes it a versatile choice for upgrading or expanding existing safety architectures.

Suitable for

• Industrial machine safety circuits
• Expanding safety outputs for emergency stop systems
• Safety light curtain integration
• Monitoring safety interlock switches
• Category 4 safety control systems

When it may not be suitable

This module is not intended for use in applications requiring voltages outside the specified 24V AC/DC range. It is also not suitable for direct control of high-power loads that exceed the rated contact capacity, as this could lead to premature wear or failure of the internal safety relays.

Key specifications

• Supply voltage: 24V AC/DC
• Contact configuration: 4 normally open (NO) and 2 normally closed (NC)
• Connection type: Spring terminals
• Safety category: Category 4

How to use

The module should be installed by a qualified professional within a protected control cabinet. Connect the safety inputs from your primary safety controller to the module's input terminals, ensuring that the power supply matches the 24V AC/DC requirement. Use the spring terminals to securely attach the necessary control wiring for your safety devices. Once installed, verify the circuit functionality by performing a system test to ensure that all safety contacts engage and disengage correctly according to the safety logic.

What to consider before purchase

• Verify that your existing safety controller supports expansion modules.
• Ensure the 24V AC/DC power supply is stable and correctly rated.
• Check that the number of NO and NC contacts meets your specific circuit requirements.
• Confirm that the spring terminal connection type is compatible with your existing wiring standards.

Usage recommendations

Always adhere to local electrical safety regulations and the manufacturer's installation manual when integrating this module into a safety circuit. Regularly inspect the connections and perform periodic functional testing to maintain the integrity of the safety system.
