Bistable/pulse relay with memory RPB-1PM-U24, 1P contact, 24 V AC/DC, 16 A /250 V AC 864389

Bistable/Impulse relay with memory – reliable lighting control

This impulse relay, also known as bistable, is an ideal solution for controlling lighting in public and residential buildings. Its memory design allows for a permanent setting of the circuit state – on or off – without the need to continuously maintain the control signal. This is particularly useful in systems where several buttons are to control a single lighting circuit.

The RPB-1PM-U24 relay is characterized by high reliability and durability, confirmed by its manufacture in accordance with European standards. DIN 35mm rail mounting simplifies installation and integration with existing electrical systems. The use of AgSnO2 contacts ensures good conductivity and corrosion resistance, and a load capacity of 16A/250V AC allows control of most standard lighting loads.

Application and functionality

This relay is dedicated to working with momentary buttons, allowing you to turn the lighting on and off from multiple points. Thanks to the memory function, the circuit state is maintained even after the control power is cut off, which increases user comfort and saves energy. The possibility of using both DC and AC 24V makes it versatile in various electrical installations. The width of the installation module (17.5 mm) allows for efficient use of space in electrical panels.

Construction and parameters

The RPB-1PM-U24 relay has been designed with simplicity of installation and reliability in mind. The modular housing provides protection against external factors (IP20), and the solid construction guarantees a long service life. The rated input voltage of 24V AC/DC ensures compatibility with a wide range of control systems. The relay has one changeover contact (1P), which simplifies connection diagrams and minimizes the risk of errors during installation. Additionally, an LED indicates the relay's on status, making system diagnostics easier.
