Bistable relay BIS-411, DIN rail mounting BIS-411

Bistable relay for intelligent lighting control

The BIS-411 bistable relay is a reliable solution for controlling lighting or other devices from multiple points. It allows convenient switching of circuits using parallel-connected buttons, eliminating the need for traditional stairwell switches. It is an ideal solution for both installers and end-users looking for functionality and comfort in their homes.

Application and functionality

The BIS-411 relay operates on the principle of an impulse – a short press of a button changes the state of the relay (switches the circuit on or off). This allows you to control the lighting from any number of locations, increasing ease of use. The device is particularly useful in large rooms, corridors or stairs, where traditional switches are inconvenient to use. Importantly, after a power failure, the relay retains its last state – it does not return to the off position, providing additional safety and comfort.

Installation and compatibility

The BIS-411 relay is designed for mounting on a standard 35 mm DIN rail, making it easy to install in an electrical distribution board. It is compatible with illuminated buttons (with an impulse current below 5 mA), allowing you to create an aesthetic and functional lighting control system. The maximum load current is 16 A, allowing control of most typical lighting loads. The device operates at 230 V AC.

Construction features and parameters

The BIS-411 relay is characterized by a solid construction and high quality workmanship. It has one changeover contact (NO/NC), providing flexibility in circuit configuration. Its compact size (1 module – 18 mm wide) allows it to be easily placed in a limited space in the distribution board. The device's power consumption is only 0.7 W, which translates to low energy consumption. Operation in the temperature range from -25°C to +50°C guarantees reliable operation in various environmental conditions. The IP20 protection class provides basic protection against touch and contamination.
