## Summary description

The Relpol RPB-1PM-UNI is a bistable latching relay designed for impulse-controlled switching. It features a 1P contact configuration with a 16A rating and supports a wide universal supply voltage range of 12-240V AC/DC. This relay is ideal for lighting control systems and automation applications where a stable state must be maintained after the control impulse is removed.

## Long description

The Relpol RPB-1PM-UNI is a high-performance bistable latching relay engineered for reliable impulse-controlled switching. This device is designed to maintain its contact state even after the control signal is removed, making it an essential component for modern electrical installations. With a robust 1P contact configuration and a 16A current rating, it provides dependable performance across a wide range of industrial and residential applications. The unit is built to handle a universal supply voltage range of 12-240V AC/DC, ensuring compatibility with diverse power systems without the need for multiple relay variants.
Advantages
The primary benefit of the Relpol RPB-1PM-UNI is its bistable operation, which eliminates the need for a continuous control signal to keep the circuit closed or open, thereby reducing energy consumption and heat generation. Its universal voltage input simplifies inventory management and installation, as a single device can be deployed in various projects regardless of the specific control voltage. The 16A switching capacity allows it to handle significant electrical loads, while the compact design ensures it fits efficiently into standard distribution boards and control cabinets.
Suitable for
Lighting control systems in hallways and staircases
Automation of electrical circuits requiring state memory
Remote switching of devices via momentary push-buttons
Energy-efficient building management systems
When it may not be suitable
This relay is not intended for applications requiring high-frequency switching or rapid cycling, as the mechanical components have specific operational limits. It is also not suitable for circuits exceeding the 16A rated current or for environments where extreme moisture or dust could compromise the internal contact mechanism.
Key specifications
Contact configuration: 1P (Single Pole)
Rated current: 16A
Supply voltage range: 12-240V AC/DC
Control type: Impulse-controlled
Mounting: Standard DIN rail
How to use
The relay is designed for installation on a standard DIN rail within an electrical enclosure. Connect the power supply to the designated input terminals and wire the load through the 1P contact terminals. The control input should be connected to a momentary push-button or a similar impulse-generating device. Once an impulse is received, the relay switches its state and remains in that position until the next impulse is detected. Ensure all connections are tightened according to the technical documentation to prevent overheating and ensure long-term reliability.
What to consider before purchase
Verify that the total load current does not exceed 16A
Ensure the control signal source provides a valid impulse
Check the available space in your distribution board for DIN rail mounting
Confirm that the application requires a latching function rather than a standard monostable relay
Usage recommendations
For optimal performance and longevity, ensure that the relay is installed in a well-ventilated enclosure and protected from extreme environmental conditions. Regularly inspect the terminal connections during routine maintenance to ensure they remain secure.
