Relpol RPB-2PSM-UNI Sequential Bistable Relay with Memory, 2P 16A, 12-240V AC/DC

The Relpol RPB-2PSM-UNI is a high-performance sequential bistable relay equipped with integrated memory, engineered for precise switching in diverse electrical installations. This device is designed to maintain its switching state even after a power supply interruption, ensuring consistent operation in automated systems. With a versatile input voltage range of 12-240V AC/DC and a robust 2P contact configuration rated for 16A, it provides a reliable solution for modern electrical control requirements.

Advantages

The primary benefit of this relay is its sequential operation combined with state memory, which allows for complex switching sequences without the need for additional logic controllers. The wide supply voltage range ensures compatibility with various industrial and residential power systems, simplifying inventory and installation. Its 16A contact rating makes it suitable for handling significant electrical loads, while the bistable mechanism ensures energy efficiency by only consuming power during the switching pulse.

Suitable for

• Lighting control systems in residential and commercial buildings
• Automation of sequential switching tasks
• Industrial control panels requiring state retention
• Energy-efficient electrical load management

This relay may not be suitable for applications requiring high-frequency switching or rapid cycling, as the mechanical nature of the bistable relay is optimized for occasional state changes rather than continuous high-speed operation. It is also not intended for use in environments with extreme vibration or high levels of electromagnetic interference that could affect the internal memory mechanism.

Key specifications

• Contact configuration: 2P (Double Pole)
• Rated current: 16A
• Supply voltage range: 12-240V AC/DC
• Functionality: Sequential bistable with memory

To use the Relpol RPB-2PSM-UNI, connect the control signal to the designated input terminals and the load to the output contacts according to the wiring diagram provided on the device housing. Ensure that the supply voltage is within the specified 12-240V AC/DC range before activation. The relay will toggle its state upon receiving a control pulse, and the internal memory will store the current position, allowing the device to resume the correct state immediately upon power restoration.

What to consider before purchase

• Verify that the 16A current rating is sufficient for your specific load requirements
• Ensure the control voltage source is compatible with the 12-240V AC/DC input
• Confirm that the 2P contact configuration meets your circuit design needs

For optimal performance and longevity, ensure that the relay is installed in a clean, dry environment within a standard electrical distribution board or enclosure. Regularly inspect the terminal connections to ensure they remain tight and free from oxidation.
