Bistable/pulse relay with memory RPB-2PSM-UNI, 2x1P contacts, 12...240 V AC/DC, 16 A /250 V AC, sequential 864392

Pulse-bistable relay – reliable lighting control

The RPB-2PSM-UNI relay is a multifunctional device designed to control lighting in public and residential buildings. Its construction based on a bistable, sequential operation with memory allows for convenient switching of circuits from multiple points using button impulses. The universal rated voltage of 12…240 V AC/DC ensures wide compatibility with various electrical installations.

Functionality and application

The RPB-2PSM-UNI relay stands out for its ability to operate in several modes, including sequential with memory function. This means that after a power failure, the relay retains its last state, which is particularly important in applications requiring continuous operation. The rated load current of 16 A / 250 V AC allows for controlling most standard lighting loads. This makes it ideal for lighting control systems in public buildings, offices, corridors or apartments. The ability to cooperate with different types of control buttons (momentary or illuminated) increases the flexibility of the installation.

Construction and parameters

The relay is housed in a mounting module housing with a width of 17.5 mm, which facilitates mounting on a standard 35 mm rail. Contacts made of AgSnO2 guarantee high reliability and durability. The universal rated voltage (12…240 V AC/DC) eliminates the need to use many different relay models for different supply voltages. The use of high-quality materials and a solid construction ensure long-lasting and trouble-free operation of the device. The relay has two changeover contacts (2x1P), which allows controlling two independent circuits or one circuit with higher power. The minimum duration of the control impulse is ≥ 55 ms, which ensures stable operation of the device even with short impulses.
