Bistable group relay with memory, DIN rail mounting, 230V, with inrush relay 160A/20ms BIS-412M-LED

Bistable relay for advanced electrical installations

This bistable relay from the BIS-412M-LED series is a reliable solution for controlling lighting and other electrical devices, especially in group systems such as hotels or public buildings. Its design allows control from multiple points, increasing user comfort and installation flexibility. The relay is characterized by high resistance to surge currents, making it perfectly compatible with modern light sources such as LEDs and energy-saving fluorescent lamps.

Versatility and functionality

The BIS-412M-LED relay offers both local and central control. Local control allows switching the load on and off using momentary button pulses, while central control allows simultaneous switching of all relays in a group. Additionally, the relay has a built-in memory that remembers the last contact position after a power failure – a very useful function in hotel or office systems. The ability to work with backlit buttons (while maintaining a current limit ≤5mA) expands the range of applications.

Solid construction and easy installation

The relay is designed for mounting on a standard 35mm DIN rail, making it easy to integrate with existing electrical infrastructure. Compact dimensions (1 module – 18mm wide) allow for efficient use of space in the distribution board. Made of high-quality materials, it ensures long-lasting and trouble-free operation. Screw terminals with a cross-section of 2.5 mm² guarantee a secure connection of wires. The rated current of 16A (with a surge of 160A/20ms) allows handling most standard loads.
