Bistable-pulse relay RPB-1ZI-U24, 1 normally closed contact, 24 V AC/DC, 16 A /250 V AC, withstand 120 A 864387

Bistable pulse relay – reliable lighting control

The RPB-1ZI-U24 relay is a device designed to control lighting in public and residential buildings. Its bistable design, operating on an on-off principle without memory, allows for convenient and efficient circuit management. The use of this type of relay is particularly beneficial where switching lighting from different points or remote control is required.

Construction and application

The relay is designed for mounting on a DIN rail, which simplifies its installation in electrical distribution boards. Compact dimensions (width 17.5 mm) allow for efficient use of space. Equipped with a single normally open contact (1Z), it enables control of various types of loads. The contact material – AgSnO2 – ensures good conductivity and durability. The relay works with momentary bell push buttons and control buttons, providing great flexibility in system configuration.

Resistance and operating parameters

One of the key features of this relay is its high resistance to surge currents – up to 120 A for 20 ms. This means that it can easily handle the switching of devices with high power consumption, such as motors or transformers. A load capacity of 16 A at a voltage of 24 V AC/DC guarantees safe and reliable operation in standard electrical installations. The rated input voltage is 24 V AC/DC (50/60 Hz), which ensures wide compatibility with various power sources. Protection class IP20 provides basic protection against touch and contamination.
