## Long description

The Relpol RPB-1ZMI-UNI is a high-performance bistable latching relay engineered for precise electrical circuit control in both industrial and residential environments. This device features a 16A 1NO contact configuration and is equipped with a built-in memory function, ensuring that the relay maintains its last switching state even after a power interruption. Designed for versatility, it operates on a universal voltage supply, making it a reliable component for modern automation systems that require consistent and energy-efficient switching performance.
Advantages
The primary benefit of this bistable relay is its ability to maintain its state without continuous power consumption, which significantly improves energy efficiency in control circuits. The inclusion of a memory function provides enhanced operational reliability by ensuring the system returns to its previous state following a power failure. Furthermore, the robust construction allows for a surge capacity of 80A for 20 ms, providing the durability needed to handle high inrush currents often associated with lighting or motor loads. Its universal voltage compatibility simplifies inventory management and installation across diverse electrical infrastructures.
Suitable for
Lighting control systems in residential and commercial buildings
Industrial automation and control panels
Energy-efficient switching applications
Systems requiring state retention after power loss
This relay may not be suitable for applications requiring high-frequency switching cycles beyond its mechanical and electrical endurance ratings. It is also not intended for use in environments with extreme moisture, dust, or corrosive gases unless housed in an appropriate protective enclosure.
Key specifications
Contact configuration: 1NO (Normally Open)
Rated current: 16A
Surge capacity: 80A (20 ms)
Function: Bistable with memory
Supply voltage: Universal
Installation should be performed by a qualified professional in accordance with local electrical regulations. The relay is typically mounted on a standard DIN rail within a control cabinet. Ensure that the control signal and load circuits are correctly wired to the designated terminals. Once installed, the relay responds to control pulses to toggle the contact state, which is then held mechanically or electronically depending on the specific internal design, ensuring stable operation.
What to consider before purchase
Verify that the 16A current rating is sufficient for your specific load requirements
Ensure the control voltage range matches your existing automation system
Check available space in your electrical distribution board for DIN rail mounting
Confirm the compatibility of the 1NO contact configuration with your circuit design
For optimal longevity and performance, ensure that the relay is protected from excessive vibration and extreme temperature fluctuations. Regularly inspect terminal connections to prevent overheating caused by loose wiring.
