Its multifunction capability allows for various operational modes, providing engineers and technicians with the versatility required to solve complex automation challenges. The robust construction ensures consistent performance under varying conditions, while the wide time adjustment range offers significant flexibility for both short-interval processes and long-duration monitoring tasks.

Suitable for

• Industrial automation systems
• Lighting control and building management
• Process control and timing sequences
• HVAC system management
• Motor control circuits

When it may not be suitable

This relay is not intended for high-power direct switching applications that exceed its rated contact capacity. It is also not suitable for environments requiring specialized explosion-proof protection or extreme high-frequency switching cycles that fall outside the specified operational parameters.

Key specifications

• Contact configuration: 1P (Single-pole)
• Timing range: 1 second to 10 days
• Supply voltage: 12-240V AC/DC
• Frequency: 50/60 Hz
• Multifunction capability

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 a control cabinet. Once mounted, connect the power supply to the designated terminals and configure the desired timing function and duration using the adjustment dials located on the front panel. Ensure all connections are secure and that the voltage input matches the specified range before energizing the circuit.

What to consider before purchase

• Verify that the contact rating is sufficient for your specific load requirements.
• Ensure the mounting space is compatible with standard DIN rail dimensions.
• Confirm that the selected timing function aligns with your automation logic.
• Check that your control circuit voltage falls within the 12-240V AC/DC range.

Usage recommendations

Always perform a functional test of the timing sequence before integrating the relay into a critical production process to ensure the settings meet your operational requirements.
