Relpol RPC-1MC-UNI Multifunction Time Relay 1P 12-240V AC/DC 1s-10d

The Relpol RPC-1MC-UNI is a high-performance multifunction time relay engineered for precise timing control in diverse electrical applications. This compact device features a single-pole contact configuration and is designed to operate seamlessly across a broad supply voltage range of 12-240V AC/DC, making it highly adaptable for various industrial and residential electrical systems. With an extensive timing range spanning from 1 second to 10 days, it provides the flexibility needed for complex automation tasks.

Advantages

The primary benefit of this relay is its exceptional versatility, as it combines multiple timing functions into a single, reliable unit. Its wide input voltage compatibility eliminates the need for specific voltage-matched relays, simplifying inventory and installation processes. The robust construction ensures long-term operational stability, while the intuitive adjustment interface allows for quick and accurate configuration of time intervals, reducing setup time in demanding environments.

Suitable for

• Industrial automation and control systems
• Building management and lighting control
• Heating, ventilation, and air conditioning (HVAC) systems
• Delayed start or stop sequences for machinery
• Process control in manufacturing lines

When it may not be suitable

This relay is not intended for applications requiring high-current switching directly through the relay contacts without an external contactor. It is also not suitable for environments exposed to extreme moisture, corrosive gases, or excessive vibration that exceeds standard industrial protection ratings.

Key specifications

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

How to use

Installation should be performed by a qualified professional in accordance with local electrical regulations. The relay is designed for standard DIN rail mounting. Once mounted, connect the power supply to the designated terminals and wire the controlled load through the output contact. Use the front-facing dials to select the desired timing function and duration. Always verify the wiring against the provided schematic before applying power to the circuit.

What to consider before purchase

• Ensure the load current does not exceed the relay contact rating
• Verify that the timing functions available meet your specific application requirements
• Check the available space in your electrical cabinet for DIN rail mounting
• Confirm that the control voltage matches your system output

Usage recommendations: Regularly inspect the terminal connections for tightness and ensure the device is kept free of dust and debris to maintain optimal performance over its service life.
