Relpol RPC-1WU-UNI Time Relay, 1P, 1s-10d, 12-240V AC/DC, Delay on Operate

The Relpol RPC-1WU-UNI is a high-performance single-pole time relay engineered for precise timing control in industrial and automation environments. This device offers a versatile delay-on-operate function, allowing for seamless integration into complex electrical circuits where timed switching is required. With its universal supply voltage compatibility and an extensive timing range, it serves as a robust solution for managing equipment operations and process automation.

Advantages

The primary benefit of this time relay is its exceptional flexibility, provided by the wide supply voltage range of 12-240V AC/DC, which eliminates the need for multiple device versions in a single system. The unit is designed for reliability and ease of use, featuring a broad timing range that spans from one second up to ten days. Its compact construction ensures it fits efficiently into standard control cabinets, while the high-quality internal components guarantee consistent performance even in demanding industrial conditions.

Suitable for

• Industrial automation systems
• Lighting control circuits
• Motor start-up delay sequences
• HVAC equipment management
• Process control and monitoring

When it may not be suitable

This relay is designed for standard industrial timing applications and may not be suitable for high-frequency switching tasks that require millisecond precision. Additionally, it is not intended for use in environments with extreme moisture or corrosive gases without appropriate protective enclosure.

Key specifications

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

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 panel. Once mounted, connect the power supply to the designated input terminals and wire the controlled load through the output contacts. Use the adjustment dials on the front of the unit to select the desired time delay interval before applying power to the circuit.

What to consider before purchase

• Verify that the load current does not exceed the relay contact rating.
• Ensure the mounting space is sufficient for DIN rail installation.
• Check that the timing function matches your specific circuit requirements.

Usage recommendations

Regularly inspect the terminal connections for tightness and ensure the device is kept free from dust and debris to maintain optimal operational longevity.
