Bistable group relay with memory, DIN rail mounting, 230V BIS-412M

Bistable group relay – reliable lighting and device control

The BIS-412M bistable relay is an advanced solution for controlling lighting or other electrical devices from multiple points. It is ideal for hotel, office, or home installations where grouping of loads and the ability to control them from different locations are required. Thanks to its state memory function, the relay retains the last set position even after a power failure, which increases comfort and saves energy.

Versatile application and easy integration

The BIS-412M relay is mounted on a standard DIN rail, making it easy to install in electrical panels. It is compatible with illuminated buttons (with a current below 5mA), allowing you to create aesthetic and functional control systems. The ability to control both locally (from individual buttons) and centrally (simultaneous switching on/off of all loads) provides great flexibility in system configuration.

Solid construction and high performance

The BIS-412M relay is designed for long-term and reliable operation. Made of high-quality materials, it ensures stable operation even under high loads. Its maximum switching capacity is 16A (at cos φ = 0.6), allowing control of most typical electrical loads. Additionally, it has an NO/NC contact, which increases its versatility. The supply voltage is 230V AC, and the power consumption is only 0.7W – which translates to low operating costs.

• State memory: When power is restored, the relay returns to the state before the shutdown – an ideal solution for hotel and office systems.

• Group control: Ability to centrally switch all loads in a group on and off.

• Wide supply voltage range: Operation in the range of 165-265V AC ensures compatibility with various electrical installations.

• Cooperation with illuminated buttons: Allows you to create aesthetic and functional control systems.

• Compact dimensions: Occupies only 1 module on the DIN rail (18mm wide).

• Safety: Has contact separation for increased safety.

• Durable construction: Ensures long-term and reliable operation in various environmental conditions (-25°C to +50°C).
