Bistable relay BIS-411-2Z-24V

Bistable relay for lighting and device control

The BIS-411-2Z-24V bistable relay is a switching element that allows convenient control of lighting or other devices from several independent points. It operates on an impulse basis – each button press changes the state of the relay (turns it on or off). This is an ideal solution where independent control from different locations is needed, without the need for complex logic circuits.

Designed for DIN rail mounting, the BIS-411-2Z-24V relay finds application in both home and industrial installations. Its construction based on bistable technology ensures reliability and long life. This makes it a solid choice for both professional installers and end-users looking for a simple and effective solution.

Characteristics and application

The BIS-411-2Z-24V relay is characterized by two normally open contacts (2NO), allowing control of two independent circuits. The control voltage is 24V AC, and the maximum switching capacity for bulbs is 600W. It can be used to control various types of loads, including bulbs, fluorescent lamps and other electrical devices. Thanks to its compact dimensions (1 module – 18mm) it takes up little space in the distribution box.

It is worth remembering that this relay does not have a "memory" function of the state after a power failure – after the power is restored, the contact returns to the off position. This protects against uncontrolled switching on of receivers after a power outage. In addition, according to the manufacturer's recommendations, it should not be used with backlit buttons.

Key features and benefits

• Bistable construction: Ensures reliable switching without the need to maintain the control voltage.
• Two NO contacts: Allow control of two independent circuits.
• DIN rail mounting: Quick and easy mounting in the distribution box.
• Compact dimensions: Occupies only 1 module (18mm) in the distribution box.
• Wide power supply voltage range: Possibility of cooperation with various power systems (9÷30 V AC/DC).
• Protection against self-activation: After a power failure, the contact returns to the off position.
• Maximum switching current 5A: Ensures safe operation of the device in various conditions.
• Screw terminals 2.5 mm²: Allow solid and safe connection of wires.
