Bistable group relay BIS-412

Bistable relay for lighting and device control

The BIS-412 bistable relay is an ideal solution for group control systems, especially in hotel installations or public buildings. It allows convenient switching of lighting or other devices from multiple points, using parallel-connected control buttons. Thanks to its design, this relay works both in local and central control.

Functionality and application

BIS-412 is designed to work on a DIN rail, which facilitates installation and integration with existing electrical infrastructure. Its main advantage is the ability to create groups of relays that can be controlled centrally – all switched on or off at once – while each relay can be controlled independently using local buttons. This solution provides flexibility and ease of use. The relay works with backlit buttons, which increases its functionality in modern installations.

Worth knowing: The BIS-412 relay has a 1xNO/NC switching contact and is adapted to a load of up to 16A. 230V AC power supply ensures compatibility with most standard electrical installations.

Key features and benefits

• Group control: Ability to create groups of relays for central control of lighting or other devices.
• Local control: Each relay can be controlled independently using momentary buttons.
• Backlit button compatibility: Provides an aesthetic look and ease of use.
• DIN rail mounting: Facilitates installation and integration with existing infrastructure.
• Status indication: LED indicates power status (green) and contact status (red).
• Versatility: Suitable for various applications, including hotels, offices and homes.
• Safety: Has contact separation, which increases safety of use.

Remember! When connecting a large number of backlit buttons, pay attention to the total current draw to avoid unwanted effects, such as self-switching of the lighting.
