Bistable relay 9÷30 V AC/DC 1NO+1NC, DIN rail mounting BIS-411-1R1Z-24V

Bistable relay for lighting and device control

The BIS-411-1R1Z-24V bistable relay is a reliable solution for remote control of lighting or other electrical devices from multiple points. Its bistable technology allows the state to be changed (on/off) using short pulses, increasing ease of use and minimizing energy consumption. DIN rail mounting simplifies installation in electrical panels.

Application and functionality

This relay is ideal for lighting control systems in residential, commercial and industrial buildings. Thanks to the possibility of connecting parallel-connected control buttons, the user can switch the circuit on and off from anywhere. The lack of "memory" of the contact position ensures safety – in the event of a power failure, the relay returns to the off state, preventing uncontrolled switching on of the receivers. This is particularly important in applications where a certain behavior after a power failure is required.

Specification and operating parameters

The BIS-411-1R1Z-24V relay operates in the supply voltage range of 9÷30 V AC/DC, making it a universal solution for various electrical installations. It has one normally open (NO) and one normally closed (NC) contact, allowing flexible configuration of control circuits. The maximum switching capacity for incandescent bulbs is 600 W, and for fluorescent lamps – 300 VA, allowing control of various types of loads. The rated switching current is 5 A. It is worth noting the limitations regarding cooperation with backlit buttons – the relay does not work with them at 24V.

Mounting and compatibility

The relay is designed for mounting on a standard 35mm DIN rail, ensuring quick and easy installation. Compact dimensions (1 module – 18 mm wide) allow for efficient use of space in the distribution board. It is important to select the correct connection cables – 2.5 mm² cables are recommended, tightened with a torque of 0.4 Nm.
