Suitable for

• Industrial automation control panels
• Signal switching in electrical distribution systems
• Interlocking and control logic applications
• Integration into manufacturing machinery

When it may not be suitable

This relay is designed specifically for control circuit applications and is not intended for switching high-power loads or motors directly. It should not be used in environments that exceed its rated thermal current or voltage specifications, as this may lead to premature failure or safety hazards.

Key specifications

• Control circuit voltage: 24V AC
• Contact configuration: 3 NO + 2 NC
• Rated thermal current: 10 A
• Operating frequency: 50/60 Hz
• Dimensions: 77 x 45 x 84 mm
• Weight: 58 g
• Color: Black and Grey

How to use

Installation should be performed by qualified personnel in accordance with local electrical regulations. The relay is typically mounted on a standard DIN rail within an enclosure. Connect the control circuit wires to the designated coil terminals and the signal wires to the appropriate NO and NC contact terminals. Ensure all connections are tightened to the specified torque to prevent overheating and ensure reliable electrical contact. Before energizing the system, verify that the control voltage matches the 24V AC rating of the relay coil.

What to consider before purchase

• Verify that the 24V AC control voltage matches your existing system requirements.
• Ensure the 3 NO and 2 NC contact configuration meets your specific logic design needs.
• Confirm that the physical dimensions are compatible with your available panel space.
• Check that the operating environment is within the specified temperature and humidity limits for industrial equipment.

Usage recommendations: Regularly inspect the relay terminals for signs of wear or loose connections during routine maintenance cycles to ensure continued operational safety and performance.
