Power supply: 165–265V AC
Max. load:16 A (120 A/20 ms)
Mounting: ona 35 mm rail
With state memory. Compatiblewith backlit pushbuttons.
The BIS-411BM-LED electronic bistable impulse relay allows lighting or other equipment to be switched on or off from several different points using parallel-connected momentary (bell-type) control switches.
The button on the front panel allows direct control of the circuit without the need to press external buttons.
Bistable relay operating principle:
The load is switched on following a current pulse caused by pressing any momentary (bell) button connected to the relay. After the next pulse
the load is switched off. The relay has a so-called ‘memory’ function for the contact position, i.e. when the power is switched on, the relay returns to the state it was in when the power was switched off. The button on the housing performs exactly the same function as an external button connected to the device’s terminals.
The “LED” version of the relay has a contact designed to work with loads with high inrush current, such as: LED lamps, ESL lamps, electronic transformers, discharge lamps, etc.

NOTE!
BIS-411BM-LED 230V is compatible with backlit push-buttons(ΣI<5mA). ![]()
