The PBM-07 bistable relay is used to control lighting or any other device by means of unipolar push buttons connected in a parallel way. The relay is equipped with two outputs activated by means of impulses given to the (IN) input. It allows to control two circuits / branches simultaneously. The control impulse must be the “L” line signal. The trigger input structure enables cooperation with backlit push buttons (including LED backlight). The total current of backlight for the (IN) input can not exceed 1,5 mA. The device is designed to be mounted in distribution boards (TH35 rail). LEDs on the front panel indicate power supply (green LED) and the output status (2 x red LED).
