Bistable group relay, DIN rail mounted, with inrush relay 160A/20ms BIS-412-LED

Bistable group relay – reliable lighting and device control

This electronic bistable relay, designed for DIN rail mounting, is an ideal solution for lighting control systems in public buildings, hotels or homes. It allows convenient switching of the load from multiple points, using parallel-connected control buttons. The BIS-412-LED model is characterized by high resistance to inrush currents, which makes it particularly useful for receivers such as LED fluorescent lamps, electronic transformers or discharge lamps.

Versatile application and functionality

The BIS-412-LED relay allows you to create groups of relays that can be controlled centrally (all on/off) or independently from each local point. This flexible solution is ideal for hotel systems, where guests can control the lighting in their rooms from different locations. Additionally, the ability to cooperate with backlit buttons (with a current consumption of less than 5mA) increases user comfort.

Construction and technical parameters

The relay is mounted on a standard 35 mm rail and occupies only 1 module (18 mm wide), which allows for efficient use of space in the distribution box. AC power supply in the range of 100-265 V ensures compatibility with various electrical installations. The maximum switching current is 16 A (at cos φ = 0.6), and the impulse current can reach up to 160 A for a short time (20 ms), which guarantees safe operation with various types of loads. The NO (normally open) contact provides a standard switching function. The device is characterized by low power consumption – 0.7 W – which translates into energy savings.

Advantages for installers and users:

• Versatility: The possibility of local and central control provides great flexibility in system configuration.
• LED compatibility: The "inrush" type relay effectively handles the large inrush currents generated when switching on LED light sources.
• Compact dimensions: It takes up only 1 module on the DIN rail, which makes it easier to install in tight distribution boxes.
• Safety: Overload and short-circuit protection protects the electrical installation.
• Simple installation: Easy installation on a standard 35 mm DIN rail.
• Low power consumption: Energy saving thanks to low power consumption in standby and operation mode.
• Compatibility with backlit buttons: Increases user comfort and installation aesthetics.
