Key specifications

• Coil voltage: 24V DC
• Contact configuration: 2 change-over contacts
• Design: Single module plug-in relay
• Compatibility: LZS plug-in sockets and bases
• Package dimensions: 42 mm width, 266 mm depth, 34 mm height

How to use

To install the Siemens plug-in relay, ensure that the power supply to the control panel is completely switched off to prevent electrical hazards. Insert the relay securely into a compatible LZS plug-in base, verifying proper alignment of the pins and contacts. Ensure that the control circuit provides the required 24V DC coil voltage and that the switched loads comply with the operational limits of the change-over contacts. Once securely mounted and connected, restore power and test the switching function within the automated system.

What to consider before purchase

• Verify that your control system operates on a 24V DC power supply
• Check compatibility with existing LZS plug-in sockets or bases in your installation
• Confirm that the load requirements match the specifications of the 2 change-over contacts
• Ensure proper physical space within the control cabinet based on the package dimensions

Always disconnect the main power supply before installing, inspecting, or replacing the plug-in relay to ensure operational safety and prevent equipment damage.
