Siemens 7PV1518-1AW30 Time Relay, On-Delay, 1 Changeover Contact, 0.05s-100h, 12-240V AC/DC

The Siemens 7PV1518-1AW30 is a high-precision on-delay time relay engineered for demanding industrial automation and control environments. This device provides reliable timing functions with a single changeover contact, ensuring seamless integration into complex electrical circuits. With a broad timing range spanning from 0.05 seconds to 100 hours and a universal supply voltage compatibility of 12-240V AC/DC, it serves as a versatile solution for various switching operations in control cabinets.

Advantages

This time relay stands out due to its exceptional flexibility and robust construction. The wide-range power supply eliminates the need for multiple device variants, simplifying inventory management and installation. Its compact form factor is specifically designed to optimize space within control panels, while the precise timing mechanism ensures consistent performance across diverse industrial processes. The inclusion of a changeover contact provides added versatility for both normally open and normally closed circuit configurations.

Suitable for

• Industrial automation systems
• Timed switching in control cabinets
• Process control and monitoring
• Delay-start applications for machinery

This relay may not be suitable for applications requiring extremely high-frequency switching cycles beyond its mechanical lifespan or for environments with extreme electromagnetic interference that exceeds standard industrial protection levels. It is also not intended for direct high-power motor switching without an appropriate contactor or relay interface.

Key specifications

• Function: On-delay
• Contact configuration: 1 changeover contact
• Timing range: 0.05 seconds to 100 hours
• Supply voltage: 12-240V AC/DC
• Mounting: Standard control cabinet rail

To use the Siemens time relay, mount the device onto a standard DIN rail within your control cabinet. Connect the power supply to the designated terminals, ensuring the voltage is within the specified 12-240V AC/DC range. Use the integrated adjustment dials to select the desired time delay setting. Once powered, the relay will initiate the timing sequence upon receiving the trigger signal, after which the changeover contact will switch state according to the configured delay.

What to consider before purchase

• Verify that the 12-240V AC/DC voltage range matches your system requirements.
• Ensure the single changeover contact capacity is sufficient for your load.
• Confirm that the on-delay function aligns with your specific automation logic.

Ensure that all electrical connections are tightened securely and that the device is protected from moisture and excessive dust to maintain long-term operational reliability.
