Bistable relay, 4-gang, flush-mounted, two control circuits BIS-409

Bistable relay for smart lighting control

The BIS-409 relay is an advanced device designed to control lighting or other electrical receivers from several independent points. It is ideal for use in home, office or commercial installations where flexibility and functionality are required. Thanks to the possibility of cooperating with backlit buttons, it allows you to create modern and convenient control systems.

Functionality and application

The BIS-409 relay offers four operating modes (A, B, C, D) that allow you to adapt the operation to individual needs. Sequential switching of circuits allows you to control the lighting from different locations, and the memory function (in selected modes) ensures ease of use. The device is particularly useful in smart home systems where integration with various building automation elements is key. Flush-mounting ensures an aesthetic appearance of the installation and discreet placement of the device in the wall.

Technical characteristics and benefits

The BIS-409 relay has been designed with reliability and safety in mind. The rated switching current is 8 A, and the maximum switching capacity for bulbs is 1500 W. The device operates at a supply voltage of 100-230 V AC and a frequency of 50 Hz. This allows it to be used in most standard electrical installations. The device design allows you to connect two control circuits, which increases the flexibility of system configuration.

• Versatility: Four operating modes allow you to adapt the operation to different user needs.
• Cooperation with backlit buttons: Enables the creation of modern and aesthetic lighting control systems.
• Flush-mounting: Provides a discreet look of the installation and easy integration with the surroundings.
• Wide supply voltage range: Compatibility with most standard electrical installations (100-230 V AC).
• High reliability: Solid construction and careful workmanship guarantee long-term use.
• Two independent outputs: Allow you to control two circuits simultaneously.

It is worth remembering that when connecting a large number of backlit buttons, self-activation of the lighting or its constant illumination may occur – this should be taken into account when designing the installation. In the case of devices generating high surge currents (e.g. motors), it is recommended to use an external switching element (contactor) with appropriate parameters.
