Bistable relay 230V 1NO+1NC, DIN rail mounting BIS-411-1R1Z

Bistable relay for smart lighting control

The BIS-411 bistable relay is a practical solution for controlling lighting or other devices from several independent points. It is ideal for both home and commercial installations where convenience and functionality are important. The device allows you to turn the load on and off using momentary push buttons connected in parallel, eliminating the need for traditional stairwell switches.

The BIS-411 relay is characterized by a simple operating principle – a current pulse changes the state of the relay, and thus turns the connected receiver on or off. Importantly, after the power is lost, the relay returns to the off state, which increases safety and prevents devices from accidentally turning on. This solution makes it easy to organize convenient lighting control in your home or office.

Construction features and application

The BIS-411 relay is designed for mounting on a standard 35mm DIN rail, which facilitates its installation in electrical distribution boards. Compact dimensions (1 module – 18mm wide) allow for efficient use of space. The device works with backlit buttons (with a pulse current below 5mA), which further increases its functionality. The maximum load current is 16A, which allows you to control most typical electrical receivers. The relay has a NO/NC changeover contact, which provides flexibility in circuit configuration.

Application:

• Lighting control in residential and commercial buildings
• Automation of lighting systems
• Creation of smart electrical installations
• Replacement of traditional stairwell switches
• Controlling various electrical devices from multiple points

Technical parameters and safety

The BIS-411 relay operates at a supply voltage of 230V AC and has protection against overload and short circuit. The device's power consumption is only 0.7W, which translates to low energy consumption. The operating temperature is in the range of -25°C to +50°C, which ensures reliable operation in various environmental conditions. It is worth noting that the maximum current of the control buttons should not exceed 5mA to avoid problems with the operation of the relay. The device has a protection class of IP20, which means protection against touching with fingers and solid bodies larger than 12.5 mm – remember to mount it in a dry and well-ventilated place.
