Advantages

This safety relay offers exceptional reliability by providing a secure interface between safety sensors and machine control systems. The compact housing allows for efficient use of space within control cabinets, while the integrated screw terminals ensure a vibration-resistant and stable electrical connection. By utilizing high-quality internal switching components, the device minimizes the risk of failure and supports long-term operational stability in automated production lines.

Suitable for

• Emergency stop monitoring systems
• Safety door and gate position monitoring
• Industrial automation and control panels
• Machine safety integration

This relay may not be suitable for applications requiring high-speed switching beyond its rated mechanical life or in environments where extreme environmental conditions, such as excessive moisture or corrosive gases, exceed the specified protection rating of the housing.

Key specifications

• Operating voltage: 24V AC/DC
• Connection method: Screw connection
• Function: Safety relay for emergency stop and safety door monitoring
• Design: Compact modular housing

To install the device, mount it onto a standard DIN rail within a protected control cabinet. Connect the safety sensors to the designated input terminals and wire the output contacts to the machine control circuit. Ensure that all wiring complies with local electrical safety standards and that the power supply matches the 24V AC/DC requirement before energizing the system.

What to consider before purchase

• Verify that the 24V AC/DC voltage matches your existing control system power supply.
• Ensure the number of safety contacts meets your specific machine safety requirements.
• Confirm that the screw connection type is compatible with your current wiring infrastructure.

Always perform a functional test of the safety circuit after installation and before putting the machinery into operation to ensure that the relay correctly triggers the safety stop function.
