Bistable relay with memory 9÷30 V AC/DC, DIN rail mounting, BIS-411M-24V

Bistable relay with memory – reliable lighting and device control

The BIS-411M-24V bistable relay is a component designed to control lighting or other devices from multiple points, using parallel-connected control buttons. Its bistable technology ensures that the state (on/off) is maintained even after a power failure – thanks to the built-in memory, the relay returns to the last set position. This is an ideal solution for installations requiring reliability and energy savings.

Functionality and application

The BIS-411M-24V relay is used in lighting, heating, ventilation and other electrical device control systems. Its DIN rail mounting simplifies installation in electrical panels. Thanks to the ability to control from multiple points, it is perfect for residential buildings, offices, public facilities and industrial automation. It is worth noting its versatility – it can be powered by both AC and DC voltage in the range of 9-30V.

Key features and benefits

• State memory: After a power failure, the relay retains the last set state (on or off), which increases comfort and saves energy.
• DIN rail mounting: Allows for quick and easy installation in electrical panels, saving time and installation costs.
• Universal power supply: The ability to power with AC or DC voltage (9-30V) provides flexibility and compatibility with various electrical installations.
• High reliability: Solid construction and high-quality components guarantee long-lasting and trouble-free operation of the device.
• Wide load range: Maximum switching current of 16A allows control of various receivers, including bulbs (up to 2000W), fluorescent lamps (up to 1000VA).
• Compact dimensions: Occupies only 1 module (18mm) on the DIN rail, saving space in the panel.
• Status indication: An LED indicates the power supply status and relay operation, making diagnostics and control easier.

Supply voltage: 9-30 V AC/DC Maximum switching current: 16 A Maximum switching capacity (bulbs): 2000 W Maximum switching capacity (fluorescent lamps): 1000 VA Mounting method: DIN rail Width: 1 module (18 mm)

Important: The relay does not work with backlit buttons due to the low supply voltage. When working with receivers with high starting current, it is recommended to use an external switching element (e.g. contactor).
