Bistable relay with memory 9÷30 V AC/DC, DIN rail mounting, with inrush relay 160A/20ms BIS-411M-LED-24V

Bistable relay for lighting and device control

The BIS-411M-LED-24V bistable relay is a reliable solution for remote control of lighting or other electrical devices. Thanks to the ability to connect multiple control buttons, it allows for convenient on/off control from different points. Using a bistable relay eliminates the need for maintained switches, which translates to greater convenience and potential energy savings.

Versatile application and easy installation

The relay is designed for mounting on a 35mm DIN rail, which facilitates its installation in electrical panels. A wide range of supply voltage (9÷30 V AC/DC) ensures compatibility with various electrical installations. Additionally, the LED version with a 160A/20ms inrush relay is particularly recommended for use with receivers with high starting current, such as LED fluorescent lamps, electronic transformers or discharge lamps.

Contact position memory – user comfort

A key feature of this model is the built-in contact position memory. This means that after a power failure, the relay returns to the state it was in before the power was turned off. This function is particularly useful in applications where maintaining the last set position of the receiver is important. It works on the principle of a pulse – switching on occurs after a short press of a button, and switching off after another pulse or loss of power.

Technical parameters and safety

The BIS-411M-LED-24V relay is characterized by a maximum load current of 16A (160A/20ms). It has one NO (normally open) contact and a protection degree of IP20. It should be remembered that due to the low supply voltage, it is not recommended to use backlit buttons. If you have any doubts about selecting the appropriate relay for a specific application, it is recommended to consult a specialist or use an external switching element (e.g. a contactor) for loads with high inrush current.
