Bistable relay BIS-411B with button for manual control, DIN rail mounting

Bistable relay for intelligent lighting control

The BIS-411B bistable relay is a practical solution for controlling lighting or other devices from multiple points. Thanks to the ability to connect momentary (bell) buttons connected in parallel, you gain convenience and flexibility in space arrangement. The device is designed for mounting on a DIN rail, which facilitates installation in a distribution box. An additional button on the housing allows direct control of the circuit without the need to use external switches.

Versatile application and easy integration

The BIS-411B relay is ideal for both installers and end users. Its versatility results from the ability to cooperate with various types of buttons, including backlit ones, and a wide range of supply voltage (165÷265 V AC). The relay design ensures reliable operation and safety of use. Thanks to its compact dimensions (1 module – 18 mm), it does not take up much space in the distribution box.

Key features and benefits:

• Control from multiple points: The ability to connect any number of momentary buttons allows you to create a convenient lighting control system throughout the house or office.
• No memory of state: After a power failure, the relay returns to the off state, which prevents unexpected starting of receivers after the power returns – this increases safety and comfort of use.
• Cooperation with backlit buttons: Seamless integration with modern lighting control systems.
• DIN rail mounting: Quick and easy mounting in a standard electrical distribution box.
• Safety: Contact separation provides isolation of the control circuit from the load circuit.
• Maximum load current 16A: Allows control of most typical lighting and electrical receivers.
• Compact dimensions: Occupies only 1 module on the DIN rail, saving valuable space in the distribution box.
• Durability: Designed to operate in a wide temperature range (-25 ÷ 50 °C).

The BIS-411B relay is an excellent choice for anyone looking for a reliable and convenient solution for controlling lighting and other electrical devices. Its simple construction and ease of installation make it ideal for both professional installers and demanding home users.
